Prohibited HF frequencies:

Answer 1

VH-VXA -VH-VXU, VH-VYA -VH-VYL Flights predicated on the use of the following HF frequencies are prohibited: • 29.489Mhz • 29.490Mhz

Answer 2

The ACARS is limited to the transmission and receipt of messages that will not create an unsafe condition if the message is improperly received, such as the following conditions: • the message or parts of the message are delayed or not received, • the message is delivered to the wrong recipient, or • the message content may be frequently corrupted. • However, Pre-Departure Clearance, Digital Automatic Terminal Information Service, Oceanic Clearances, Weight and Balance and Takeoff Data messages can be transmitted and received over ACARS if they are verified per approved operational procedures

Answer 3

Use the VHF radio connected to the top of fuselage antenna for primary ATC communications on the ground

Answer 4

Maximum and minimum limits are red. Caution limits are amber.

Answer 5

Engine ignition must be on for: * takeoff * landing * operation in heavy rain * anti-ice operation

Answer 6

Intentional selection of reverse thrust in flight is prohibited.

Answer 7

Operation with assumed temperature reduced takeoff thrust is not permitted with anti-skid inoperative. ATM ok on wet runway but not permitted on contaminated runway. Derate permitted on both wet and contaminated. Don’t use ATM with widshear obs… Derated takeoff thrust (fixed derate) may permit a higher takeoff weight when performance is limited by VMCG, such as on a runway contaminated with standing water, slush, snow, or ice. This is because derated takeoff thrust allows a lower VMCG.

Answer 12

The maximum altitude with flaps extended is 20,000'

Answer 13

Holding in icing conditions with flaps extended is prohibited

Answer 14

Avoid rapid and large alternating control inputs, especially in combination with large changes in pitch, roll, or yaw (eg. large side slip angles) as they may result in structural failure at any speed, including below VA. Va: The Manoeuvring Speed (VA) of an aircraft is an airspeed limitation determined by the aircraft designer. At speeds exceeding the manoeuvring speed, full deflection of any flight control surface can result in damage to the aircraft structure. Note that some flight control inputs, such as a rapid, full deflection rudder reversal, can result in structural damage or failure even at speeds below manoeuvring speed.

Answer 15

(#)Do not deploy the speedbrakes in flight at radio altitudes less than 1,000ft Not#: In flight do not extend the speedbrake lever beyond the flight detent

Answer 16

When extending or retracting flaps with the ALTERNATE FLAPS position switch, allow 15 seconds after releasing the ALTERNATE FLAPS position switch before moving the switch again to avoid damage to the alternate flap motor clutch After a complete extend/retract cycle, ie. 0 to 15 and back to 0, allow 5 minutes cooling before attempting another extension

Answer 17

QFE operations are prohibited

Answer 18

Do not use the terrain display for navigation. Do not use the look-ahead terrain alerting and terrain display functions: within 15nm of takeoff, approach or landing at an airport or runway not contained in the GPWS terrain database

Answer 19

Avoid weather radar operation in a hangar. Avoid weather radar operation when personnel are within the area normally enclosed by the airplane nose radome. Note: The hangar recommendation does not apply to the weather radar test mode

Answer 20

Maximum tank fuel temperature is 49°C. Minimum tank fuel temperature prior to takeoff and inflight is - 43°C, or 3°C above the fuel freezing point temperature, whichever is higher. Note: The use of Fuel System Icing Inhibitor additives does not change the minimum fuel tank temperature limit

Answer 21

Intentional dry running of a center tank fuel pump (low pressure light illuminated) is prohibited. Main tanks 1 and 2 must be full if center tank contains more than 453kg Do not leave flight deck unattended with CT fuel pump running. Do not turn on CT fuel pumps if less than 453kg in CT on preflight. You’ll end up burning the 453 when you get to cruise I thinks.

Answer 22

Do not apply brakes till after touchdown.

Answer 23

Lateral imbalance between main tanks 1 and 2 must be scheduled to be zero. Random fuel imbalance must not exceed 453kg for taxi, takeoff, flight or landing

Answer 24

Use of HGS takeoff guidance as the sole means of runway centerline tracking is prohibited. The HGS is not approved for single engine fail passive rollout guidance. This does not prohibit use of the HGS rollout guidance as a supplemental aid during single engine operations.

Answer 35

For the first flight of the day, at airport elevations at or above 2,000ft MSL, if the temperature is below 5°C/41°F, consider placing the Ignition select switch to BOTH before starting the engines. This may increase the likelihood of a successful engine start on the first attempt.

Answer 39

1200kg 6.10.7.4 Emergency Fuel Declaration Final Reserve Fuel (FRF) Figure ICAO recommend that Flight Crew be provided with a fuel figure that is easily remembered upon which to base the initial assessment of the need to declare MINIMUM or MAYDAY Fuel. The intent of this nominated figure is not to dictate the actual FRF, but rather serve as a consistent trigger for Flight Crew to actively manage the remainder of the flight taking into account available fuel margins. The figures in the FAM Section 16.11 – Fleet Specific Information (Nominated FRF) have been calculated using the following data: Maximum Landing Weight; ISA+15; 1500 feet; and 30 minutes. Note: Having identified that a potential low fuel state exists, *Flight Crew may use the actual or OFP FRF figure* on which to base a declaration of Minimum or Mayday Fuel. The OFP figure takes into account variations in landing weight, atmospheric conditions and airport elevation.

Answer 44

1/2 steady HEADwind component + full gust Max Vref +15 or flap placard -5 Do not apply wind additives for steady tailwinds or tailwind gusts. Set command speed at VREF + 5kt (autothrottle connected or disconnected). Non normal = Vref + qrh additive number + wind (5min 15max) Command Speed - Non-Normal Conditions Occasionally, a non-normal checklist instructs the Flight Crew to use a VREF speed that also includes a speed additive such as VREF 15 + 15kt. When VREF has been adjusted by a NNC, this becomes the VREF used for landing. This VREF does not include wind additives. For example, if a non-normal checklist specifies “Use flaps 15 and VREF 15 + 10kt for landing”, the Flight Crew would select flaps 15 as the landing flaps and look up the VREF 15 speed in the FMC or QRH and add 10kt to that speed. When using the autothrottle, position command speed to VREF + 5kt. Sufficient wind and gust protection is available with the autothrottle connected that no further wind additives are needed. *If the autothrottle is disconnected, or is planned to be disconnected prior to landing, appropriate wind additives must be added to the VREF to arrive at command speed*, the speed used to fly the approach. For example, if the checklist states “use VREF 40 + 30kt”, command speed should be positioned to VREF (VREF 40 + 30kt) plus wind additive (5kt minimum, 15kt maximum). If a flaps 15 landing is performed and VREF ICE is required, (VREF ICE = VREF 15 + 10kt), the wind additives should not exceed 5kt.

Answer 45

For single engine F15 landings: VREF ICE = VREF 15 + 10kt. If any of the following conditions apply: *Engine anti–ice will be used *during landing* *Wing anti–ice has been used *any time during the flight* *Icing conditions were encountered during the flight and the landing temperature is below 10° C If a flaps 15 landing is performed and VREF ICE is required,the wind additives should not exceed 5kt.

Answer 46

The stall warning test requires that AC transfer busses are powered for up to 4 minutes.

Answer 47

If adverse or gusty winds are being experienced or are anticipated (approximately 30kt), consider leaving parking brake set, and consider setting stabilizer trim to 4.0 units. It is not necessary to set the park brake in order to check brake wear indicators during the exterior inspection.

Answer 53

The altimeter will under read in an above ISA atmosphere causing the aircraft to fly a slightly steeper approach. For example on an ISA +20 day the *altimeter will under read by 4% for each 10 degrees above ISA,* times the height above the airfield. This means that the aircraft will arrive at the 250’ minima 20 feet high and at the threshold 4 feet high. Air Services have a practice where they round down QNH values. For instance if the actual QNH was 1017.9 this would be reported to the aircraft as 1017. This will cause the altimeter to under read by 27 feet, as such the aircraft will fly 27 feet above the nominal path. 1hpa=30’

Answer 56

Below 200 8° (why are you turning blw 200’??) Otw basically limit it to 15° till you are + 15… Turns commenced between 50 - 200ft, should limit bank angle to 8 degrees. Above 200ft a maximum bank angle of 30 degrees is permitted at V2+15kt with takeoff flaps. (from immediate turn after TO AE) Limit bank angle to 15° until reaching V2 + 15 ( from flap retract sched) With LNAV engaged, the AFDS may command bank angles greater than 15° (from immediate turn after TO OEI); Limit BA to 15 degrees anytime below amber band (GA profile) OEI GA limit bank angle to 15: If an engine fails during go-around, perform normal Go-Around and Missed Approach procedures. Verify maximum go-around thrust is set. Maintain flaps 15, VREF 30 or 40 plus wind additive speed and limit bank angle to 15° until initial manoeuvring is complete and a safe altitude is reached. Accelerate to flap retraction speed by repositioning the command speed to the manoeuvre speed for the desired flap setting and adjusting pitch. Retract flaps on the normal flap/speed schedule.Note: VREF 30 or 40 plus wind additive at flaps 15 may result in an airspeed that provides less than full manoeuvre margin (top of the amber band)

Answer 57

135-235Kg Depends on GW, init alt, temp and climb speed. Highest heavy and low init altitudes. Climb usually not justified if cruise at new alt not at least 20mins.

Answer 58

60kts V2+15-V2+25 AE * V2-V2+20 OEI Rotation rates vary from 2° to 3° per second with rates being lowest on longer airplanes. Liftoff attitude is achieved in approximately 3 to 4 seconds depending on airplane weight and thrust setting. 11° Flaps 1 (-800) takeoffs have the least clearance. Consider using a larger flap setting for takeoffs at light gross weights. F1 8.5° pitch is 33cm tail clearance :o * V2 + 20kt is the optimum climb speed with takeoff flaps. It results in the maximum altitude gain in the shortest distance from takeoff. Acceleration to higher speeds reduces the altitude gain. If airspeed exceeds V2 + 20kt during the initial climb, stop the acceleration but do not attempt to reduce airspeed to V2 + 20kt. Any speed between V2 + 15 and V2 + 25kt results in approximately the same takeoff profile. Crosscheck indicated airspeed for proper initial climb speed.

Answer 59

Obstacle clearance, noise abatement, or departure procedures may require an immediate turn after takeoff. Initiate the turn at the appropriate altitude (normally at least 500ft HAA) and maintain V2 + 15 to V2 + 25kt with takeoff flaps. Note: Turns commenced between 50 - 200ft, should limit bank angle to 8 degrees. Above 200ft a maximum bank angle of 30 degrees is permitted at V2+15kt with takeoff flaps. After completing the turn, and at or above acceleration height, accelerate and retract flaps while climbing. Note: The possibility of an engine failure along the departure track must be considered. Special engine out procedures, if available, are preferable to a takeoff weight reduction to ensure all obstacles are cleared.

Answer 60

LNAV guidance becomes active at 50ft AGL if the active leg is within 3.0nm and 5° of the runway heading. If the departure procedure or route does not begin at the end of the runway, it may be necessary to use the HDG SEL mode at 400ft AGL to intercept the desired track for LNAV capture. When the departure procedure is not a part of the active flight plan, use HDG SEL or VOR LOC mode. When an immediate turn after takeoff is necessary, the desired heading may be preset before takeoff.

Answer 64

Up to and including 140 = 230 abv 140 up to including 200 = 240 abv 200 = 265

Answer 65

The PM should verify that takeoff thrust has been set and the throttle hold mode (THR HLD) is engaged. A momentary autothrottle overshoot of 4% N1 may occur but thrust should stabilize at +/- 2% N1, after THR HLD. Thrust should be adjusted by the PM, if required, to 0% + 1% target N1.” Inability of an engine to produce the correct takeoff thrust is considered to be a system failure and the takeoff should be rejected before 80kt.
