Q

Describe several flight situations where an unintentional spin may occur

A

Engine failure on takeoff during climb out - stretching glide leading to stall while turning back onto the runway
Crossed controlled turn from base to final - Uncoordinated turn at low speeds
Engine failure on approach to landing - stretch glide to land on runway
Go around with excessive nose-up trim - Applying go-around power with full landing configuration without the appropriate use of rudder
Go around with improper flap retraction - reducing flaps too early

Note: Just lists of general stall stations - stalls are required for spins

Q

After experiencing an engine failure immediately after takeoff (before safe maneuvering altitude), why is it usually inadvisable to attempt a landing on the runway you have just depart from?

A

Not enough altitude to make a 180-degree turn + 45 degrees to angle towards the runway; at an average descent rate of 500 ft/min and a standard rate turn of 1 min to turn 180 degrees

Q

Explain the approximate altitude loss and factors to consider, when maneuvering an airplane that has just taken off, experienced an engine failure at 300 feet AGL, and is attempting to turn back on the departure runway

A

Not enough altitude to make a 180-degree turn + 45 degrees to angle towards the runway; at an average descent rate of 500 ft/min and a standard rate turn of 1 min to turn 180 degrees. Other considerations include reaction time of situation, wind/ground speed, load factor if greater than standard rate of turn

Q

If a forced landing is imminent, should the landing gear be left up, or down and locked?

A

Depends on the situation; likely want the gear down to help absorb the impact but will expose the plane to more damage, water landings would advise to have the gears up to reduce asymmetric drag on touchdown

25
Are there any special considerations necessary when using the auxiliary pump after an engine-driven fuel pump failure?
For high wing aircraft gravity is usually enough for straight and level flight and descends, use of electric pump should be considered during climbs or fuel pressure falls below 0.5 PSI
26
What operating procedure could be used to minimize spark plug fouling?
Use of proper mixture settings
27
During a cross-country flight you notice that the oil pressure is low, but the oil temperature is normal. What is the problem and what action should be taken?
There could be a number of causes, but as long as the oil temperature remains normal then sufficient oil is still going thru the engine. It is advisable to land at the nearest airport regardless
28
If the loss of oil pressure occurs accompanied by a rising oil temperature, what is indicated?
Not enough oil is being supplied to the engine and engine failure is imminent. Reduce throttle and find a suitable landing area immediately
29
What procedure should be folowed if an engine fire develops on the ground during start?
If engine starts - Increase power to a higher rpm for a few moments then shutoff engine If engine does not start - set throttle to full, mixture off, continue to crank the engine to put out fire by vacuum If fire continues - obtain fire extinguisher; masters off; ignition off; fuel shutoff off; use fire extinguisher
30
What procedure should be followed if an engine fire develops in flight?
Throttle - closed Mixture - cutoff Fuel shutoff - off Aux fuel pump - off Master - off Cabin heat and air - off Airspeed 100 KIAS or higher to extinguish Land ASAP
31
What procedure should be followed if an electrical fire develops inside the aircraft?
All electrical devices + master - off Close vents, cabin heat, cabin air Avionics - off Use fire extinguisher Note: Keep ignition switch on
32
What troubleshooting procedure should be followed in determining the cause of an electrical fire that is not readily apparent?
After fire has been extinguish Master - on (if critical) Turn on one essential electrical device at a time Reset circuit breakers only if critical otherwise leave them
33
What procedure should be followed if a cabin fire develops in flight?
Typically caused by electrical fire so follow electrical fire checklist otherwise refer to the POH
34
What procedure should be followed if a wing fire develops in flight?
Shutoff wing-related electrical equipment (i.e. lights, pitot heat) Slide slip to avoid flames reaching the cabin area Note: Load factor limits may be compromised due to weaken wing structure from the fire
35
What are the two main categories of aircraft icing?
Structural - Icing on aircraft surfaces Induction - Icing on the engine's intake
36
Name the three types of structural ice that may occur in flight
Clear Icing - Clear in nature, slowly builds up Rime Icing - Milky white in nature, freezes on impact Mixed Icing - Mix of both clear and rime ice Note: Clear ice usually occurs when it's -10C or warmer while rime ice happens when it's colder than -15C, mixed in between those temperatures
37
What is necessary for structural icing to occur?
Visible water Freezing temperature on contact (low pressures causes temperature drops in addition to ambient temperature)
38
Describe the types of icing found in stratiform clouds, and the types found in cumuliform clouds
Stratiform clouds - Rime and mix icing found; confined on average to a layer of 3,000 to 4,000 ft but covers an extended area Cumuliform clouds - Typically clear or mixed; usually cover a defined area but not confined within a specific altitude
39
During your preflight planning, what type of meteoroglocial information should you be aware of with respect to icing?
Location of fronts - location, type, speed, and direction of movement Cloud layers - bases and tops (reference PIREPs and area forecast) Freezing levels - determine how to avoid icing and exit icing conditions Air temperature and pressure - Icing found around low pressure areas at temperature at or near freezing
40
What is the definition of the term freezing level and how can you determine where that level is?
Freezing level is the lowest altitude at a given location where the air reaches 0C Can use freezing level charts, GFA, PIREPs, AIRMETs, SIGMETs, surface analysis chart, low level significant weather chart, winds aloft, and any other relevant weather product
41
What action is recommended if you inadvertently encounter icing conditions?
Either leave the area of visible moisture or find an area above freezing Note: Whatever action is taken make an immediate decision
42
If you encounter in flight icing, and ATC asks you to report your conditions, what are the official reportable icing values that you are expected to use?
Trace, light, moderate, severe
43
If icing has been inadvertently encountered, how would your landing approach procedure be different?
Higher and faster than normal Use of flaps not recommended Avoid a missed approach
44
Which type of precipitation will produce the most hazardous icing conditions?
Freezing rain; produces the greatest amount of ice accumulation in a short period of time
45
Does the stall warning system have any protection from ice?
No unless aircraft is equiped
46
What causes carburetor icing and what are the first indications of its presence?
The drop in pressure as air passes thru the venturi of the carburetor causes cooling of the mixture; excess moisture will be deposited as frost or ice if the temperature reaches freezing levels. First indication is the loss of rpm for fixed pitch prop planes or drop in manifold pressure if constant speed prop planes
47
What conditions are favorable for carburetor icing?
Below 70F (21C) and above 80% humidity but may occur as high as 100F (38C) and 50% humidity Note: Temperature drops as much as 70-60F inside the carburetor
48
If an airplane has anti-icing and/or deicing equipment installed, can it be flown into icing conditions?
Not necessarily; refer to POH to find out if aircraft can be flown into known icing conditions and limitations
49
A pilot flying an aircraft certified for flight in known icing (FIKI) should be aware of a phenomenon known as roll upset. What is roll upset?
Roll upset is the uncommanded and uncontrolled roll caused by severe in-flight icing causing airflow separation (aerodynamic stall) which self-deflects the ailerons with degraded roll stability characteristics, especially by ice accumulation behind the boot area of the wing
50
What is the recommended recover procedure for a roll upset?
Reduce AOA by increasing airspeed; roll wings level if in a turn Set appropriate power and monitor speed and AOA (a controlled descend is much more favorable than an uncontrolled descent) If flaps extended do not retract unless upper wing surface can be cleared of ice (increased AOA otherwise) Verify wing ice protection if functioning normally by visually observing both wings
51
What is meant by decompression?
The inability to maintain the designed aircraft cabin pressure
52
What are the three types of decompression?
Explosive decompression - Cabin pressure decreases faster than the lungs can decompress (occurs in less than half a second); can only be caused by structural damage or door popping Rapid decompression - Lungs decompress faster than the cabin pressure; period of useful consciousness is severely reduced Gradual or slow decompression - Cabin pressure decreases at a rate so slow that the cabin crew may not be aware; effects of hypoxia slowly take hold; caused by small leaks within the pressure vessel
53
What are the dangers of decompression?
Hypoxia Tossed of blown out of the airplane (only at higher altitudes) Decompression sickness (nitrogen bubbles in the blood) Exposure to wind blasts and extreme cold
54
When would an emergency decent procedure be necessary?
Maneuver for descending as rapidly as possible, within structural limits, to a lower altitude for an emergency landing
55
What procedure should be followed in establishing an emergency descent?
Refer to POH Power - idle Max drag (full flaps, gear down, prop fine pitch) Establish 30 or 45 degree bank
56
What standards are you expected to maintain when demonstrating an emergency descent?
Clear the area Establish proper airspeed Demonstrate proper planning and execution Use bank angle of 30 or 45 degree Maintain airspeed +0/-10 knots and level off at +/- 100 ft Complete appropriate checklist
57
What instruments are affected when the pitot tube freezes?
Pitot tube blocked but drain clear - Airspeed stays at 0 Pitot tube and drains blocked - airspeed acts as altitmeter; high in climb, low in descent
58
What instruments are affected when the static port freezes?
Airspeed indicator - with functioning pitot port airspeed would indicate slower when climbing and faster when descending Altimeter - stuck at whichever altitude port was forzen VSI - indicate level flight
59
Does the pitot system have any protection from ice?
Pitot heat; consists of heating element within pitot tube, switch, 10 amp circuit breaker
60
What corrective action is needed if the pitot tube freezes? If the static port freezes?
Pitot - turn pitot heat on Static - use alternate air; break the face of a static instrument (VSI or ASI)
61
What indications should you expect while using alternate air?
If alternate source is within the cabin where static pressure is usually lower than outside: Altimeter - higher than actual Airspeed - higher than actual VSI - momentary climb then stabilize Note: Refer to POH for more info
62
What instruments may be relied upon in the event of a complete vacuum system failure while operating in instrument meteorological conditions?
Turn and slip/turn coordinator - bank info Magnetic compass - bank info Airpeed - pitch info Altimeter - pitch info VSI - pitch info
63
Is there a backup system available if the engine driven vacuum pump were to fail?
Depends on the aircraft see POH
64
What recommended procedure should be used in resetting a tripped circuit breaker?
Not be reset unless stated in a checklist or in the judgement of the PIC is necessary for completion of safe flight Note: Repeated resetting can lead to further circuit damage, component damage, or lead to fire or explosion
65
Interpret the follwing ammeter indications Positive Negative
+ After starting - Battery being recharged after draining from starting; if full scale charge is indicated after 1 min then starter likely still engaged During flight - Faulty voltage regulator causing over charging - After starting - Normal during start otherwise alternator not functioning or overloaded system and battery is not charging During flight - Alternator not functioning or overload in system; battery to charging
66
What action should be taken if the ammeter indicates a continuous discharge (left needle) while in flight?
Alternator not working; check all switches are on, cycle alt switch, if problem prosists: Alt switch off, pull circuit breaker All nonessential electrical equipment powered off Terminate flight and land asap
67
What action should be taken if the ammeter indicates a continuous charge (right needle) while in flight (more than two needle widths)?
Excessive charge would destroy the battery electronics subject to overvoltage which a sensor should detect and apply the checklist including: Alt switch off, pull circuit breaker All nonessential electrical equipment off Terminate flight and land asap
68
If the low voltage warning light illuminates, what has occurred?
Light with the ammeter showing a discharge could mean system load is greater than the alternator (low rpm ground ops) or alternator has been shut off (shutdown procedure or overvoltage was detected)
69
If a positive gear down indication is not received, what action is recommended first?
Use the appropriate checklist which may include Master - on Landing gear and gear pump breakers in Landing gear light test Use another operating bulb if one is burnt out
70
What recommended procedure should be used if the landing gear fails to restrict after takeoff?
Use the appropriate checklist which may include Masters - on Land gear level - up Landing gear and gear pump breakers in Landing gear light test Recycle landing gear lever Check for gear motor operation by examining ammeter and listening for noise Note: If you can hear gear running 1 min after gear up then pop gear pump circuit breaker and reset when needed for landing
71
How is the emergency gear extension system operated?
Hand pump; see POH for location
72
What is the recommended procedure if the landing gear will not extend normally?
Use the appropriate checklist including Master - on Landing gear lever - down Landing gear and gear pump circuit on Use emergency hand pump until heavy resistance encountered Gear down light - on Secure pump handle
73
What procedure should be followed if a pilot does not receive a positive indication of the gear down and locked?
Attempt to extend the gear manually, if unsuccessful prepare for a gear up landing. Use the appropriate checklist including Complete before landing checklist Normal approach and configuration Landing gear and gear pump circuit in Initiate low tail landing Use minimal braking Taxi slowly Shutdown and inspect gear
74
What is the recommended procedure in dealing with a flat main landing gear tire?
Normal approach and configuration Touchdown with good tire first and keep aircraft off flat tire for as long as possible Use braking on good wheel as required to maintain directional control
75
What is the recommended procedure to follow if the nose gear is unsafe or the tire is flat?
Complete before landing checklist Shift as much weight to the rear as possible (cargo and passengers) Flaps normal Unlatch all doors Once committed to landing set avionics and masters off Initiate slightly tail low landing Mixture - idle Ignition - off Fuel selector - off Hold nose off for as long as possible After landing evacuate aircraft
76
Why should taxiing on a slush, snow, or ice covered taxiway in a retractable gear airplane be avoided?
Thawing conditions can pick up mud and slush into the wheel wells and then freeze again adversely affecting the landing gear system; cycling gear after takeoff may help but best to avoid such conditions
77
What is an asymmetrical flap emergency?
One flap deploys or retracts while the other remains in position
78
What procedure should be followed in an asymmetrical flap emergency?
Apply opposite aileron and rubber, likely full deflection is required; land with higher than normal airspeed to avoid stalling
79
What procedure should be followed if loss of elevator control occurs?
Extend landing gear Flaps - 10 Trim for level flight Use throttle and elevator trim to establish 70 knots (slow flight) Only use throttle control pitch; only during landing flare apply full nose up trim and cut the throttle at the moment of touchdown
80
What procedure should be followed if a cabin door accidentally opens in flight?
Establish straight and level flight Trim for 80 KIAS Open a window Momentarily push door out and then pull in and lock
81
What procedure should be followed if a baggage door opens in flight?
Do not attempt to close; by design door should remained closed while in flight
82
What two factors should be considered in choosing the type of survival equipment to carry for a flight over an uninhabited area?
Type of climate Type of terrain
83
