0.01 Mach.

Explanation
aim. RAC 8.2.1: Once accepted, the Mach number shall be adhered to within .01 Mach, unless atc approval is obtained to make a change, if an immediate temporary change in Mach number is necessary (e.g. because of turbulence), atc must be notified as soon as possible.

25
Q

At 14.000 feet, the maximum speed in a holding pattern for a civil turbojet aircraft is _____ KiAS

A

230

Explanation

aim. RAC 10.7: The size of the protected airspace for a holding pattern is based on aircraft speed, unless otherwise noted on the charts or when a shuttle procedure is specified (see RAC 10.9). holding patterns must be entered and flown at or below the airspeeds listed in Table 10.1 below: Maximum Holding Airspeeds:
- At or below 6 000 ft ASL 200 KIAS;
- Above 6 000 ft ASL up to and including 14 000 ft ASL: 230 WAS;
- Above 14 OOO ft ASL: 265 KIAS.

NOTES:

  1. At Canadian military airfields, the size of the protected airspace is for a maximum of 310 kias. unless otherwise noted.
  2. For helicopter procedures (COPTER), the maximum holding airspeed is 90 was. unless otherwise noted.

Pilots are to advise atc immediately if airspeeds in excess of those specified above become necessary for any reason, including turbulence, or if they are unable to accomplish any part of the holding procedure. After departing a holding fix. pilots should resume normal speed subject to other requirements, such as speed limitations in the vicinity of controlled airports, specific atc requests, etc.

NOTE: in areas where turbulence is known to exist holding patterns may be designed for speeds of 280 kias.

27
Q

What is the final assurance of a safe takeoff in case of icing condition?

A

The pre-takeoff inspection

Explanation

aim. air 2.12.2: (b) Critical Surfaces: Critical surfaces of an aircraft mean the wings, control surfaces, rotors, propellers, horizontal stabilizers, vertical stabilizers or any ocher stabilizing surface of an aircraft which, in the case of an aircraft that has rear-mounted engines. :nc!udes the upper surface of its fuselage. Flight safety dunng ground operations in conditions conducive to frost, ice or snow contamination requires a knowledge of:
(l) adverse effeccs of frost, ice or snow on aircraft performance and flight characteristics, which are generally reflected in the form of decreased thrust, decreased lift increased drag, increased stall speed, trim changes, altered stall characteristics and handling qualities;

(10 various procedures available for aircraft ground de-icing and anti-icing, and the capabilities and limitations of these procedures in various weather conditions, including che use and effectiveness of freezing point depressant (FPD) fluids:

(ill) holdover time, which is che escimaced cime that an application of an approved de-icing/anti-icing fluid is effective in preventing frost, ice. or snow from adhering to created surfaces. Holdover time is calculated as beginning at the start of the final application of an approved de-icing/anti-icing fluid and as expiring when the fluid is no longer effective. The fluid is no longer effective when its ability to absorb more precipitacion has been exceeded. This produces a visible surface build-up of contamination. Recognition that final assurance of a safe takeoff rests in the pre-takeoff inspection.

28
Q

Winglets are devices that:

A

Decrease induced drag.

Explanation

The winglets are installed on some aircraft to prevent creacion of wing dps vortices (induced drag). Their main purpose is felt during flight phases requiring minimum induced drag as the climb (for better performances) and che cruise (for minimum fuel consumption).

An disadvantage of this device is that it creates some parasite (form) drag.

29
Q

What is the purpose of vortex generators located on the leading edges of jet aeroplanes?

A

Delay the separation of the boundary layer.

Explanation

vortex generators are small plates of about 2.5 cm standing in a line, with a certain angle of attack, on the wing’s leading edge. They generate vortices that delay or prevent the breakaway of the boundary layer by re-creating it.

30
Q

What is the movement of the aircraft around its normal (or vertical) axis called?

A

Yaw

Explanation
The normal axis, also called ‘vertical axis.” is the imaginary line that runs vertically through the aircraft centre of gravity, around which the movement is called yaw. it is controlled by the rudder pedals acting on the rudder.

31
Q

Whac is the purpose of a mass balance?

A

Eliminate the risk of vibration of the control.

Explanation
Some flutters can occur during high-speed flights. To present this, manufacturers balance the controls by placing a streamline shaped mass ahead of the concrol surface hinge. This mass is called mass balance.

32
Q

In a fixed shaft turboprop engine, the propeller is driven by:

A

The turbine.

Explanation

in a free turbine turboprop engine, the air coming in through the air intake is compressed by an axial compressor before entering the combustion chamber. The hot gases coming out drive the compressor turbine. They drive the separate power turbine which drives the propeller shaft. The propeller speed is reduced at a fraction of the speed at which the turbine drives the shaft by means of the gearbox.

In the fixed shaft turboprop, the compressor and the shaft are both driven by the turbine. The propeller then rotates at the same speed as the main engine shaft. This engine makes more noise on the ground and is more demanding on the starter rotor than free turbine turboprop engines.

33
Q

in a compressor, what is the purpose of the bleed valve?

A

Prevent the stall of the compressor.

Explanation
a surge bleed valve is a device used in compressors to prevent them from stalling. They are located at critical points of the compressor and open under the control of the Fuel Control unit (FCU).

34
Q

To measure thrust of a turbofan engine. N1 is mainly used. What is N1?

A

The speed of the low-pressure spool.

There are different techniques to measure the thrust of a gas turbine engine:

  • the Engine Pressure Ratio, which is the total pressure ratio across a jet engine;
  • N1, which is the speed of the low-pressure compressor and turbine (low-pressure spool): mainly used for turbofan and turbojet engines;
  • N2. which is the speed of the high-pressure compressor and turbine (high-pressure spool);
  • the fuel flow.
35
Q

Regarding a piston-engine aircraft, why is it more economical to fly at high altitude than at low altitude with the same power setting?

A

Because the lesser air density results in a greater TAS.

Explanation
The IAS which gives the greater range remains the same with the altitude (due to a same angle of attack). However, for a same IAS. the TAS will be greaterat high altitude than at low altitude. On average, the true airspeed increases of 2% every 1.000 feet above 20.000 feet and 1.5% every 1.000 below 20.000 feec.

36
Q

SAE Type I fluids:

A

Provide very limited anti-icing protection.

Explanation

aim. AIR Zl2.2:(g) SAE and iso Type i Fluids: These fluids in the concentrated form contain a minimum of 80% glycol and are considered “unthickened” because of their relatively low viscosity. These fluids are used for de-icing or anti-icing. but provide very limited anti-cing protection.

37
Q

in order to fly ifr. the air data computer of the autopilot must be checked and certified every:

A

24 months.

Explanation

CAR Standard 625. Appendix C Altimeters and other Altimetry devices installed in aircraft operating under instrument Flight Rules, or under visual flight rules in Class B and C Airspace or Class C and D Airspace that is designated as Transponder Airspace” shalI be calibrated at intervals not exceeding 24 months, to the parameters and tolerances outlined in Appendix B of Standard 571, or to equivalent standards acceptable to the Minister.

For the purpose of this section, the term “altimetry devices” includes any air data computer, or other barometric device, providing a flight crew station, or an auto pilot, or automatic pressure altitude reporting system, or altitude alerting system with altitude data derived from static pressure.

38
Q

Before descending below the MDA while following a FMS computer-generated GP. you should:

A

Visually scan for obstacles.

Remind that OCSs on LNAV procedures below the MDA have not been assessed.

Know that obstacles may penetrate the computer-generated flight path.

Explanation

aim. AIR 2.16.1: CAUTION: Caution should be exercised when descending below the MDA while following a FMS computer-generated GP. unlike vertically guided approaches, which have their ocss verified below the DA OCSs on lnav procedures below the MDA have NOT been assessed. As a result obstacles may penetrate the computer-generated flight path. Pilots are reminded to visually scan for obstacles before descending below the MDA

39
Q

What can you tell me about TCAS and transponders?

A

intruder aircraft equipped with only a Mode A transponder are not tracked or detected by TCASI

intruder aircraft without transponders are invisible to TCAS-equipped aircraf.

in an encounter between two tcas II-equipped aircraft, the equipment will provide traffic advisories (TAs) and coordinated vertical resolution advisories (RAs).

Explanation

AIM, COM 9.1: There are two types of TCAS:

(a) TCAS i is a system which includes a computer and pilot display^ that provides a warning of proximate traffic (TA) to assist the pilot in the visual acquisition of intruder aircraft and in the avoidance of potential collisions (it does not provide ras).
(b) TCAS il is a system, which includes a computer, pilot displays), and a Mode S transponder, that provides both TAs and vertical plane ras. ras include recommended escape manoeuvres, only in the vertical dimension, to either increase or maintain existing vertical separation between aircraft. NOTE: There is currently no tcas equipment capable of providing RAS in the lateral direction.

The following paragraphs and table describe the tcas levels of protection versus aircraft equipage.

(a) intruder aircraft without transponders are invisible to TCAS-equipped aircraft and thus TAs or ras are not provided.
(b) intruder aircraft equipped with only a Mode a transponder are not tracked or detected by tcas ii. because tcas ii does not use Mode A interrogations. Mode A transponder aircraft are invisible to TCASequipped aircraft.
(c) intruder aircraft equipped with a Mode C transponder without altitude input wi l be tracked as a non-altitude replying target. Neither a data tag nor a trend arrow will be shown with the traffic symbol. These aircraft are deemed to be at the same altitude as own aircraft
(d) in an encounter between two tcas n-equipped aircraft their computers will communicate using the Mode S transponder data link, which has the capability to provide complementary ras (e.g. one climbing and one descending).

Refer to the tables.

40
Q

If the temperature at which an aircraft is flying for a given altitude is higher than the standard temperature, how will the aircraft’s true altitude compare to the indicated altitude?

A

it will be higher.

Explanation
With too high an altimeter setting, the altimeter indicates a too high altitude. Each 0.10 inch of mercury added to che altimeter setting increases the indicated altitude on the altimeter by about 10O feet. From a region of high pressure to a region of low pressure, the altitude indicated by the altimeter (not corrected) is higher than the actual altitude. The same thing occurs when che altimeter passes from a warm air mass to a cold air mass.

The opposite occurs from a low pressure to a high pressure from a region of cold air to a region of warm air.

41
Q

What is the principle on which the vertical speed indicator operates?

A

It measures the difference between the rapid change of pressure inside the aneroid capsule and the relatively slow race at which this pressure is equalized in the housing in which the instrument is located.

Explanation
The vertical speed indicator is an instrument indicating the aircraft rate of climb or descent in feet per minute. Connected to the static pressure system, it is sensitive to barometric pressure changes occurring every time the altitude changes. The static pressure source pressure is directly led to the aneroid capsule in the instrument case. The air leaks from the case by a capillary tube at a relatively slow rate. The vertical speed indicator needle reacts to the difference between the quick change of the pressure in the aneroid capsule and the relatively slow rate at which the pressure is equalized in the case.

42
Q

The altimeter error, resulting from mountain waves and nonstandard temperatures, can be as much as:

A

3000 ft

Explanation
Mountain effect error is caused by a wind blowing at altitude above mountain ranges. This wind will create mountain waves which are going to cause the wrong reading of the altimeter, in addition to the mountain waves, if the air temperature is different from the standard temperature (which is often the case), the altimeter may indicate an error of up to 3.000 feet higher than true altitude.

43
Q

The turn and bank indicator shows attitude changes through:

A

This instrument does not indicate attitude changes.

The turn and slip indicator and the turn coordinator work on the gyroscopic precession principle.

When the aircraft turns, a couple of forces moving the gyro around a vercical axis appear. Because of precession, the tilt occurs 90º further in the same direction as the rotation. The tilt occurs on the side opposite the turn on a horizontal axis, a reversing device drives the needle (or the aircraft model) on the ocher side. i.e.. in the direction of the turn.

The steeper the turn, the stronger the couple of forces applied to the gyro, and the bigger the tilt due to the precession force.

The turn and slip indicator merges two instruments: the needle and the ball. The needle indicates direction and the aircraft rate of turn, and the ball indicates the amount of bank, which is subject to the centrifugal force and to gravity, allowing it to indicate if there is a skid or slip.

The turn coordinator replaces the turn and slip indicator in a lot of aircraft it works on the same principle, but the supporting ring of the gyro is tilted at approximately 35º to the aircraft longitudinal axis, allowing it to react to yaw and roll.

44
Q

Apparent drift appears on heading indicators even if they work correctly. They will drift by approximately 15º per hour because of:

A

The Earth s rotation while the gyroscopic axis remains fixed in space.

Explanation
The heading indicator’s apparent drift (or precession) is caused by the earth’s rotation, whereas the gyro stays fixed in space. The heading indicator’s gyro then has an apparent movement relative to the earths rotation below.

45
Q

Which of the following instruments) work(s) on the principle of gyroscopic precession?

A

The turn and bank indicator and the turn coordinator.

The turn and slip indicator and the turn coordinator work on the gyroscopic precession principle.

When the aircraft turns, a couple of forces moving che gyro around a vercical axis appear. Because of precession, che alt occurs &0e further in the same direction as che rotation. The tilt occurs on the side opposite the turn on a horizontal axis, a reversing device drives the needle (or che aircraft model) on the ocher side. i.e.. in the direction of the turn.

The steeper the turn, che stronger the couple of forces applied to the gyro, and che bigger the alt due to the precession force.

46
Q

What does the EFIS consist of? What kind of information does it transmit to the pilot?

How many displays can we see in EFIS installations?

What are the characteristics of these displays?

A

The amount of information displayed in an EFIS may vary a lot

The EFIS is an electronic flight instrument system.

Explanation

An EFis (Electronic Flight instrument System) is a flight deck instrument display system using electronic technolog/ instead of electromechanical, usually, the EFIS consists of a PFD (Primary Flight Display^ MFD (Multi-Function Display) and EICAS (Engine indicating and Crew AJercing System) display.

EFIS installations vary from one to six or more display units.

The pfd displays all the information critical to flight in a single display (improving the pilot’s situational awareness): CAS. heading, attitude, altitude, vertical speed and yaw.

The pfd increases situational awareness by alerting the pilots (with colour changes or audio alerts) of unusual or potentially dangerous situations (low airspeed, too high rate of descent, etc)

The MFD displays navigational (aircraft route, restricted airspace, aircraft traffic, aircraft glide radius, location over terrain, ecc.) and weather information from various systems (on-board radar, lightning detection sensors or ground-based sensors). The MFD can also change the colour or shape of the data to alert pilots of dangerous situations, it can also display information about aircraft systems and engines (EiCAS/ECAM).

47
Q

how many degrees are in standard time zone? Are they degrees of longitude or latitude?

A

15; longitude.

Explanation
The earth is divided into 24 time zones of 15º longitude. These zones are numbered from 1 to 12 around the prime mendian. The change of day occurs on che 180th meridian. An hour is therefore equal to 15º of longitude.

48

5 Gallons

49
Q

Question 49

Refer to image 1 in the Appendix.

Between Midland VOR/DME and North Bay VOR/DME. you notice that you have drifted from your track. You decide to set your VOR on Midland vor and your adf on Muskoka ndb. you put 009 on the OBS of your VOR. The needle is centred with a from indication. Your adf indicates 104. what is your position?

50
Q

Consider two situations to approach and land at two different airports. Airport A is located at an elevation high above sea level, while Airport B is located at sea level. The aircraft, temperature and wind are identical in both situations. Considering this information, the groundspeed during the final approach to Airport B will be ____ than the groundspeed during the final approach to Airport A.

A

Lower

Explanation

Density alcitude affects aircraft performance and stall speed. The higher the altitude, the lower the air density. An aircraft moving in air that is less dense will need to move faster to meet the same quantity of particles, and to create the same lift as if it was in a denser air. The indicated airspeed becomes lower than the true airspeed as the altitude increases.

a rule of thumb to calculate an approximate true airspeed is to apply the following correction:

  • For altitudes between mean sea level and 20.000 feet, add 1.5% to the indicated airspeed every 1.000 feet of pressure altitude;
  • For altitudes starting at mean sea level and rising above 20.000 feet, add 2% to the indicated airspeed every 1.000 feet of pressure alcitude.
51
Q

As the aircraft altitude increases, the true stall speed _____ and the indicaced stall speed _____

A

increases; remains the same.

Explanation

Density alcitude affects aircraft performance and stall speed. The higher the altitude, the lower the air density. An aircraft moving in air chat is less dense will need to move faster to meet che same quantity of particles, and to create the same lift as if it was in a denser air. The mdicaced airspeed becomes lower chan the true airspeed as che altitude increases.

a rule of thumb to calculate an approximate true airspeed is to apply che following correction:

  • For altitudes between mean sea level and 20.000 feet, add 1.5% to the mdicaced airspeed every 1.000 feet of pressure altitude;
  • For altitudes starting at mean sea level and rising above 20.000 feet, add 2% to the indicated airspeed every 1.000 feet of pressure alcitude.

The stalling true airspeed is greacer at a higher altitude, but the scalling indicated airspeed stays the same.

52
Q

in winter, when temperatures are much lower than ISA. you should fly:

A

At least 1.000 feet above che MEA/MOCA

Explanation

aim. RAC 8.5: When temperacures are extremely cold, true altitudes will be significantly lower than indicated altitudes. Although pilots may fly ifr at che published MEA/MOCA

53
Q

Does a wing always stall at the same angle of attack?

A

Yes

Explanation

When respecting the manufacturer’s recommendations, an aircraft will stall at its critical angle of attack regardless of its power, airspeed, altitude or attitude.

54
Q

Which of the following performances is obtained with a maximum L/D on a propeller aircraft?

A

Maximum range and maximum gliding distance.

Explanation

“Right Training Manual”, Exercise 10 “Right for Range and Endurance”:

Angle of Attack; As far as the aerodynamics of the aircraft arc concerned, maximum range is achieved when the aircraft is being operated at the angle of attack giving the greatest ratio of lift to drag. The angle of attack that gives the best lift/drag ratio for a given aircraft will always be the same and is not affected by changes in altitude or gross weight.

55
Q

What is manoeuvring speed?

A

The highest speed at which an aircraft can be stalled without causing structural damage.

Explanation

Manoeuvring speed (va) is the maximum airspeed at which the full defleccion of all available aerodynamic controls will not create overload on the aircraft. This airspeed is in each aircraft owner manual. In turbulent air, you should never exceed this airspeed in order to not go beyond the limit load factor and damage the aircraft primary structure.

Manoeuvres where the approach to a stall or the full uses of the rudder or the ailerons is necessary must not be made at an airspeed above va.

56
Q

What is vr?

A

The rotation speed.

Explanation
aim. GEN 1.7: vr: Rotation speed

57
Q

What is vmc?

A

The minimum control speed with critical engine inoperative.

Explanation
AIM. GEN 1.7: Vmc: Minimum control speed with critical engine inoperative.

58
Q

At V1. the pilot can:

A

Abort the takeoff and stop the aeroplane on the remaining runway length plus the stopway. or continue takeoff in order to reach vr then V2 at 10.7 metres above the runway end.

Explanation

Accelerate Stop Distance Available (ASDA): The length of the takeoff run available plus the length of the stopway, if provided.

The accelerace-stop distance is the distance required to accelerate the aeroplane up to its VI. then completely stop it (for example in case of engine failure at Vi or before).

The accelerace-go distance is the distance required to accelerate the aeroplane up to its V1. reach its vr after an engine failure at its V1. then reach its V2 at 10.7 metres (35 feet) above the runway.

The decision speed (or engine failure recognition speed) (V1) is an indicated airspeed. The pilot decides to continue or stop the takeoff after the failure of one engine based on this speed and the remaining runway length.

V1 may vary according to the aeroplane weight. The pilot may therefore make arrangements to have the accelerate-stop distance equalling the accelerace-go distance: what is called balanced field length, it allows a takeoff with the highest weight possible regarding runway length and conditions.

59
Q

During a landing on a wet runway, a distracced pilot brakes too abruptly, causing a slip of the aircraft main wheels, leading to a loss of adhesion, what is this type of hydroplaning called?

A

Reversion rubber hydroplaning.

Explanation
Reverted-rubber hydroplaning can occur on a wet or icy runway when a tire stops turning: it skids and heats, causing the rubber to de-vulcanize. The rubber particles collect behind the tire, forming a dam that presents the water from escaping correctly. The trapped water heats and passes into the vapour phase. The steam pressure ends up lifting che tire off the ground.

60
Q

You are on final approach to land when a wind shear causes the headwind to become a very strong tail wind. What is the first action to take?

A

Push on the control column to avoid stall.

Explanation
We assume a wind going from ml to 10 knots tailwind, or a headwind abruptly decreasing of 10 knots (negative wind shear): inertia leads to a delay of seconds before the aircraft reacts to this change. During this time, the aircraft speed decreases of about 10 knots, if this decreasing occurs during approach, when aircraft is flying at low speed, the approach slope will be suddenly more pronounced and a stall could occur, you should therefore increase power.

61
Q

In non-radar departure. ATC will apply a 3-minute delay between a light aircraft (departing after) and:

A

Medium aircraft if the light aircraft is departing from an intersection.

Explanation

aim, RAC 4.1.1: controllers will apply a three-minute separation interval to any aircraft that takes off into the wake of a known heavy aircraft, or a light aircraft that takes off into the wake of a known medium aircraft if:

  • the following aircraft starts its takeoff roll from an intersection or from a point further along the runway than the preceding aircraft; or
  • the controller has reason to believe that the following aircraft will require more runway length for takeoff than the preceding aircraft

ATC will also apply separation intervals of up to three minutes when the projected flight paths of any following aircraft will cross chat of a preceding heavy aircraft.

62
Q

Consider two runways with a length of 7.000 feet. Runway A has a CLEARWAY length of 1.000 feet. Runway B has a STOPWAY length of 2.000 feet, in this case, the TORA of Runway A is _____ feet and its ASDA is _____ feet. Regarding Runway B. the TODA is _____ feet and its ASDA is _____ feet.

A

7000; 7000; 7000; 9000

Explanation

aim. aga 3.8: A stopway is defined in the Aerodrome Standards and Recommended Practices (TP 312) as “a rectangular area on the ground at the end of take-off run available prepared as a suitable area in which an aeroplane can be stopped in the case of a rejected takeoff”, where paved, it is marked over its entire length with yellow chevrons (when its length exceeds 60 m) as shown in aga 5AZ Figure 5.6. and is lit with red edge and end lights in the take-off direction, its length is included in che accelerate-stop distance available (ASDA) declared for the runway.
aim. aga 3.9: A clearway is defined in che Aerodrome Standards and Recommended Practices (TP 312) as “a defined rectangular area over land or water under the control of the aerodrome operator, selected as a suitable area over which an aircraft may make a portion of its initial climb to a specified height”.
aim. aga 3.10: The Canada Air Pilot (CAP) provides information on declared distances, which are defined in che fifth edition of the Aerodrome Standards and Recommended Practices (TP 312) as follows:

“The distances chat the aerodrome operator declares available for aircraft take-off run. take-off distance, accelerate stop discance. and landing distance requirements. These distances are categorized as follows:

(a) Takeoff Run Available (TORA): The length of runway declared available and suitable for the ground run of an aircraft taking off.
(b) Takeoff Discance Available (TODA): The length of che takeoff run available plus the length of che clearway, if provided.

(0 Accelerate Stop Distance Available (ASDA): The lengch of the takeoff run available plus the length of che scopway. if provided.

(d) Landing Discance Available (LDA): The length of the runway available and suitable for the ground run of an aircraft landing.”

63
Q

The _____ of an aircraft is the weight of this aircraft multiplied by its distance from the balance datum line.

A

Moment.

Explanation

The moment (or balance moment) of an aircraft is the weight of this aircraft multiplied by its distance from che balance datum line.

64
Q

Imagine an aircraft loaded as follows:

  • weight on the ramp: 8.360 lbs
  • CG position: 85.8 inches aft of datum

just before starting the engines, a passenger decides not to take off because he/she is too scared. This passenger weights 230 lbs and was seated 95 inches aft of datum, where is the new CG of the aircraft without this passenger?

A

85.5 inches aft of datum.

Explanation

For this question, you must deduct the moment of the person who disembarks from the aircraft from the aircraft’s total moment before they disembarked, and deduct their weight from the aircraft’s total weight before they got off. with the results you get. you will be able to calculate the centre of gravity.

we know that: Moment = Weight x Arm

The loaded aircraft total moment was: 8.360 x 85.8 = 717.288 pounds per inch.

The moment of the people who disembark is: 230 x 95 = 21.850 pounds per inch.

The new aircraft moment is now: 717.288 • 21.850 = 695.438 pounds per inch.

The new aircraft weight is: 8.360 ■ 230 = 8.130 pounds.

The new aircraft centre of gravity is: 695.438 / 8.130 = 85.54 inches aft of datum.

65
Q

Refer to image 2 in the Appendix.

According to the conditions below, determine VI:

  • Temperature at the airport: ao5C
  • Elevation: 2.300 feet
  • Altimeter setting: 28.12 inches of mercury
  • Aircraft gross weight: 17.000 lbs
  • Headwind: 10 knots

To use this speed graph, use the altitude pressure at the airport.

Here, it is 4000 feet.

Draw a straight vertical line from the temperature (in eq on the inferior index. From the intersection point between the straight line and the curve standing for the pressure altitude (in feet), draw a straight horizontal line to the graph end.

66
Q

Refer to image 3 in the Appendix.

According to the following information, determine the required fuel and the trip time:

  • Trip distance: 2OOO NM
  • Flight altitude: 33.000 feet asl
  • Headwind: 50 kts
  • Temperature: 10=C below standard
  • Landing weight: 550.000 lbs
A

104,000 pounds; 5 hours 6 minutes.

Explanation

First, find che wind outlined on che wind index (on the bottom left): draw a straight horizontal line to che right. Now. find the trip discance on the inferior index of the graph. From this distance, draw a scraighc vercical line to che wind reference line. From the reference line, follow the wind curve (downward if it is a tailwind and upward if it is a headwind) to the scraighc horizontal line drawn previously. From the intersection point, draw a straight vertical line up to the top of che graph.

The fuel required will be determined with the intersection point between the straight vertical line drawn earlier and the first curve representing the flight pressure altitude. From this intersection point, draw a straight horizontal line to the right to the landing weight reference line. On the inferior index of the landing weight, draw a straight vertical line upward beginning at the estimated landing weight. From che previous intersection point, draw a line chat follows the weight curve to che straight vertical line that you just drew. Now. from this intersection point, draw a straight horizontal line up to the right index. Here, you can read the fuel required in these conditions.

The trip time will be determined with the intersection point between the scraighc vercical line drawn in che pre/ious step and the second curve standing for the flight pressure altitude. From this intersection point, draw a straight honzoncal line from the left to the temperacure reference line. On the inferior index of the temperature, draw a scraighc vertical line upward beginning at the temperature outlined. From the intersection point of the previous step, draw a line that follows the temperature cun;e to che straight vertical line chat you just drew. Now. from this intersection point, draw a straight horizontal line to che left index. Here, you can read che trip time in these conditions.

67
Q

Refer to image 4 in the Appendix.

According to the information below, determine the recommended landing distance with reverse thrust:

  • Aircraft type: Turboprop
  • Runway: 25 at CYOW
  • wind: Nil
  • unfactored landing distance on bare and dry run way: 4,000 feet
  • Current CRFI: CYOW CRFI RWY 07/25 - 4C .30 1201191200
A

7.540 feet.

Explanation

The answer is the intersection between the given CRFi (0.30. at the top of the table) and the given unfactored landing distance (4.000 feet, at the left of the table): 7.540 feet.

aim. air 1.6.7:1. The recommended landing distances in Table 2 are based on a 95 percent level of confidence. A 95 percent level of confidence means that in more than 19 landings out of 20. the staced distance in Table 2 will be conservative for properly executed landings with all systems serviceable on runway surfaces with the reported CRFi.
2. The recommended landing distances in Table 2 take into account the reduction in landing distances obtained with che use of discing and/or reverse thrust capability for a turboprop-powered aeroplane and with the use of reverse thrust for a turbojet-powered aeroplane. Table 2 is based on the landing distances recommended in Table 1 with additional calculations that give credit for discing and/or reverse thrust. Representative low values of discing and/or reverse thrust effect have been assumed, hence the data will be conservative for properly executed landings by some aeroplanes with highly effective discing and/or thrust reversing systems.
3. The recommended landing distances in CRFi Table 2 are based on standard pilot techniques for che minimum distance landings from 50 ft. including a stabilized approach at VRef using a glide slope of 3° to 50 ft or lower, a firm touchdown, minimum delay to nose lowering, minimum delay time to deployment of ground lift dump devices and application of brakes and discing and/or reverse thrust, and sustained maximum antiskid braking until stopped, in Table 2. che air distance from the screen height of 50 ft to touchdown and che delay distance from touchdown to the application of full braking remain unchanged from Table 1. The effects of discing/reverse thrust were used only to reduce the stopping distance from the application of full braking to a complete stop.
4. Landing field length is the landing distance divided by 0.6 (turbojets) or 0.7 (turboprops), if the afm expresses landing performance in terms of landing distance, enter the Table from the left-hand column. However, if the AFM expresses landing performance in terms of landing field length, enter the Table from one of the right-hand columns, after first verifying which factor has been used in the AFM.

68
Q

Ice on the wing can cause:

A

An increased stall speed and a decreased rate of climb.

Explanation
An accumulation, even very fine, of frost, snow or ice on the aircraft surfaces will impair ics charactenstics. On the airfoils, a thin layer of frost affects che uniform airflow on the wing’s upper surface and causes boundary layer separation. The stall speed will increase and the stall angle of attack will decrease. Snow or ice accumulation will affect even more aircraft charactenstics. With an important accumulation, the aircraft would be unable to take off. the stall speed being so high. An increase in the aircraft’s weight plays a role as well, though less important on the stall speed increasing. Before caking off. it is imperative to remove all traces of snow, ice or frost from the aircraft, in flight, avoid icing conditions if the aircraft is not equipped for chose conditions.

69
Q

Among the following factors, which can influence whether frost, ice or snow will accumulate, cause surface roughness on an aircraft and affect the anti-icing properties of freezing point depressant fluids?

A
1	- Ambient temperature
2	- Aircraft surface temperature
3	- De-icing and anti-icing fluid type
4	- De-icing and anti-icing fluid temperature
5	- Relative humidity
6	- Wind speed
7	- Wind direction
8	- De-icing and anti-icing fluid concentration

Explanation

aim. air 2.12.2: (d) More than 30 factors have been identified that can influence whether frost, ice or snow will accumulate, cause surface roughness on an aircraft and affect the anti-icing properties of freezing point depressant fluids. These factors include ambient temperature: aircraft surface temperature; the de-icing and ana-icing fluid type, temperature and concentration; relative humidity: and wind speed and direction. Because many factors affect che accumulation of frozen contaminants on the aircraft surface, holdover times for freezing point depressant fluids should be considered as guidelines only, unless che operators ground icing operations program allows otherwise.

70
Q

What can you tell me about wing tip vortices?

A

Vortices normally settle below and behind the aircraft.

Lateral movement of vortices, even in a no wind condition, may place a vortex core over a parallel runway.

With a light cross-wind, one vortex can remain stationary over the ground for some time.

Explanation

aim. air 2.9.1: Because of ground effect and wind, a vortex produced within about 200 feet agl tends to be subject to lateral drift movements and may return to where it started. Below 100 feet agl. the vortices tend to separate laterally and break up more rapidly than vortex systems at higher altitude. The vortex sink rate and levelling off process result in little operational effect between an aircraft in le.’el flight and other aircraft separated by 1 OOO feet vertically. Pilots should fly at or above a heavy jet’s flight path, altering course as necessary to avoid the area behind and below the generating aircraft, vortices start to descend immediately after formation and descend at the rate of 400 to 5CO feet per minute for large heavy aircraft and at a lesser rate for smaller aircraft, buc in all cases, descending less chan I OOO feet in total in 2 minutes.

vortices spread out at a speed of about 5 KT. Therefore, a crosswind will decrease the lateral movement of the upwind vortex and increase the movement of the downwind vortex. Thus, a light wind of 3 to 7 kt could resulc in the upwind vortex remaining in the touchdown zone for a period of time or hasten the drift of the downwind vortex toward another runway. Similarly, a call wind condition can move the vortices of the preceding landing aircraft forward into che touchdown zone.

71
Q

With regard to a flight itinerary, the “responsible person” means an individual who:

A

Has agreed to report the aircraft overdue.

Explanation

CAR 602.70: Responsible person: means an individual who has agreed with the person who has filed a flight itinerary to ensure that the following are notified in the manner prescribed in this Division, if the aircraft is overdue, namely.

  • an air traffic control unit, a flight service station or a community aerodrome radio station, or
  • a Rescue co-ordination centre, (personne de confiance)
72
Q

Consider an aeroplane that requires a thrust of 2.000 pounds to fly at 200 knots. To fly at 400 knots, this aeroplane will need a thrust of:

A

8.000 pounds.

Explanation
If you wish to increase an aeroplanes airspeed with the weight and configuration remaining the same, you must give more thrust (or power). To double an aircrafts airspeed, the thrust must be increased four times.

73
Q

What is a Reduced visibility Operations Plan (RVOP)?

A

A plan that calls for specific procedures established by the aerodrome operator and/or atc when aerodrome visibility is below RVR 2600 (1/2SM) down to and including rvr 1200 (1/4 SM).

Explanation

Reduced/Low Visibility Operations Frequently Asked Questions (FAQs):

  1. What is a Reduced visibility Operations Plan (RVOP)?

it is a plan that calls for specific procedures established by the aerodrome operator and/or ATC when aerodrome visibility is belcw RVR 2600 (1/2SM) down to and including RVR 1200 (1/4 SM).

74
Q

How can the maximum operating Mach number of an aeroplane be defined?

A

The maximum operating speed of the aeroplane in relation to the speed of sound.

Explanation

Mach tuck is an aerodynamic effect where the aircraft nose tends to pitch downward as the airflow around the wing reaches supersonic speeds. The aircraft will first experience this effect below Mach 1; it then gradually increases as the speed is increasing above the critical Mach number (Merit), and becomes dangerous if the aircraft speed exceeds the maximum operating Mach number (Mmo).

Mmo is shown on the airspeed indicator by a barber pole.

74
Q

The critical Mach number may be defined as:

A

Number below which no airflow on the aircraft is supersonic.

Explanation
The critical Mach is the number beyond which appears, on the upper surface of a wing, an area where the airflow reaches then exceeds the local speed of sound.

The critical Mach number (Merit) may be defined as the speed at which the first shock waves will be created on some parts of the aircraft (usually the wing’s upper surface, where the airflow is moving faster).

75
Q

What effect would a light cross-wind have on the wing tip vortices generated by a large aeroplane that had just taken off? A light cross-wind:

A

Could cause one vortex to remain over the runway for some time.

Explanation

aim. air 2.9.1: vortices spread out at a speed of about 5 KT. Therefore, a crosswind will decrease the lateral movement of the upwind vortex and increase the movement of the downwind vortex. Thus, a light wind of 3 to 7 kt could result in the upwind vortex remaining in the touchdown zone for a period of time or hasten the drift of the downwind vortex toward another runway. Similarly, a tail wind condition can move the vortices of che preceding landing aircraft forward into the touchdown zone.

76
Q

What is one of the advantages of a sweepback wing?

A

To delay the formation of high-speed drag by delaying the formation of the first shock wave.

Explanation
The advantages of sweepback wings are not only lateral and directional stability: they also delay the formation of shock wave at high speed by presenting a longer chord to the airflow than a conventional wing. The critical Mach number will be higher.

77
Q

What is the biggest danger when ice forms on an aircrafts wings?

A

its stall speed increases considerably.

Explanation

By accumulating on lifting surfaces, ice can modify their profile. This change leads to an increase in drag and a decrease in lift. An ice layer with the thickness of sandpaper destroys lift by 30% and increases drag by 40%. The consequence of this effect is an increase in stall speed. The mass of accumulated ice is the least dangerous factor.

78
Q

You are in climb when you have a sudden sensation of ear-popping. This is caused by:

A

The pressure inside your ear was greater than the outside pressure. The Euscachian tube opened to equalize the pressure.

TP 12864E - Human Factors For Aviation - Advanced Handbook => Chapter 4: Physiology - Flying at High Altitudes:

Cabin Depressurization and Trapped Gases • Barotitis: The most common form of trapped gas is barotitis, or middle ear block, in flying, this occurs during ascents or descents, and is most noticeable closer to the ground. The air in the middle ear is unable immediately to equalize with the changing oucside pressure because the Eustachian tube is blocked, especially in cases of inflammation due to a cold or allergy. During ascents, the pressure in the middle ear is higher than the outside pressure and causes the eardrum to bulge outward, sometimes painfully. During descents, the outside pressure is greater and causes che eardrum to bulge inward, in cases of extreme pressure differential, che eardrum may even rupture, thus alleviating the. pain but likely resulting in temporary grounding.

The standard techniques for clearing middle ear block are yawning, swallowing or using the valsalva manoeuvre, which consists in holding the nose and blowing out gently against it (as if blowing che nose), in most cases, this will open the Eustachian tube and equalize the pressures.

79
Q

What is a low visibility Operations Plan (LVOP)?

A

A plan that calls for specific procedures established by the aerodrome operator and/or atc when aerodrome visibility is below RVR 1200 (1/4 SM).

Explanation
