- Cabin altitude / Rapid depressurisation
- Dual engine failure
- Engine fire
- Engine limit / surge / stall
- Engine severe damage / separation

- Flight deck door / auto unlock light flashing
- Unscheduled stabiliser trim
How many un-annunciated non-normal checklists are there?
31 checklists (examples… Aborted engine start, engine surge/limit/stall, unreliable airspeed)
What are the 7 scenarios that require an emergency landing?
- One main hydraulic system remaining
- One main AC power source remaining
- When trouble occurs in the altimeter, and a correct altitude cannot be confirmed with related procedures or a standby altimeter
- The non-normal checklist contains the words “Plan to land at the nearest suitable airport”
- Cabin smoke or fire which cannot be immediately and positively determined to be extinguished or eliminated
- Engine failure or engine fire
- Any other situation where significant adverse effects on safety may be possible if flight is continued (illegal activity, sick passenger)
5. What checklists contain the words “Plan to land at the nearest suitable airport”?
- PACK OFF (if both packs have failed)
- Window damage
- AC BUS OFF (if both BUS OFF lights remain illuminated)
- Engine failure / shutdown
- Reverser unlocked (if REV is annunciated and accompanied by yaw, loss of speed or buffet)
- Volcanic ash
- APU FIRE
- CARGO FIRE
- ENGINE FIRE
- WHEEL WELL FIRE
- Smoke / fire / fumes

6. What is the difference between the windshear escape manoeuver and the GPWS escape manoeuver?
- The windshear manoeuver can be flown manually or automatically
- The GPWS manoeuver is ALWAYS flown manually
- The initial pitch attitude for windshear is 15 degrees
- The initial pitch attitude for GPWS is 20 degrees
- Windshear follows FD commands, whereas GPWS doesn’t and can go up to PLI
- If positive visual verification is made under day VMC prior to PULL UP warning, correct the flight path immediately until the aural
- Reason for making 15 deg NU for w/shear – higher the pitch attitude the higher the windshear recover ability is, but at the same time
need to consider stick shaker margin – therefore 15 deg is a compromise on both recovery ability and stick shaker margin.
- PWS “GO-AROUND WINDSHEAR AHEAD” – during approach, normal go-around ok.
What is VMO / MMO?
Winglet equipped 340 / 0.86M
Winglet not equipped 360 / 0.86M
What is the maximum crosswind limit for a wet ungrooved runway?
9. When is the EICAS message cross-reference list used?
1. Prior to block out: Used to confirm the appropriate MEL for the displayed EICAS message
2. After block out but prior to the beginning of the take-off: Referred to make a decision to continue the flight or return to
blocks for displayed EICAS message after NNC completed.
**NB** Does not apply if adequate maintenance action has been carried out such as application of MEL, or the
message is a status message confirmed by maintenance as nuisance.
! GTB – No dispatch
! GTB (PIC) – The associated MEL contains any maintenance action/operational requirement turn back unless PIC
makes a decision to continue the flight based on his experience or referring the information from maintenance or
! FP/OP – Flight can be continued if the operational requirement (flight plan or operation procedure) of associated
MEL is satisfied. The list of associated criteria for FP/OP is contained at back of x-ref list.
! MAY GO – The flight may continue without restriction
! Display of EICAS Warning, Caution, Advisory after block-out prior to beginning of take-off – refer to x-ref list (after
completion of NNC).
! Display of Status Message after block out prior to take-off – may disregard after completion of both engines
10. What causes the APU to perform an automatic protective shutdown (pack control selector switches)?
When both pack control selectors are turned off quickly, high outlet bleed air is turned off very quickly, and bleed air in the duct can
surge and reverse. Therefore turn off one pack, and when the corresponding pack off light illuminates, the other pack control selector
may be turned off
Following an APU automatic protective shutdown, can the APU be immediately restarted?
No - The APU cannot start until the air inlet door is closed. This will take approximately 30 seconds
12. If the APU performs an automatic protective shutdown during a pushback, what are some considerations?
If the particular APU has a history of auto-shutdowns, select the APU bleed air switch off first, then turn off the packs, then turn the
APU bleed back on for engine start.
APU auto-shutdown cause by fluctuation of bleed duct pressure duct pressure and surging. The outlet of bleed air is momentary
sealed causing an upsurging and back-pressure of the APU compressor section.
- The APU cannot be restarted for approx. 30 seconds due to the inlet door closing
- The parking brake can still be set
- The interphone system is still powered
- The passenger address system is still powered
- Only the left VHF is powered
- The instrument panel floodlights, the standby magnetic compass light, integral lights for essential instruments on the left side and
centre panel and overhead panels are automatically switched to the Standby AC bus. The aisle stand light is also available. This will
be the only lighting available, so the flight deck will be relatively dark
What are the APU starter cycle limitations?
The starter duty cycle is a maximum of three consecutive starts or attempts within a 60-minute period
14. What is the maximum crosswind limit on a grooved wet runway?
The FMC will provide navigation, guidance, and map display between which latitudes?
Between 87 degrees north and 87 degrees south
16. The IRS will provide valid magnetic heading and track between which latitudes?
Between 73 degrees north and 60 degrees south IN NAV MODE
17. What are some indications of volcanic ash?
(A FIRES AMBRSS)
- Smoke or ash in the cockpit or cabin
- A acrid smell similar to electrical smoke
- Multiple engine malfunctions such as stalls, increasing EGT, fluctuating parameters, torching from tailpipe etc.
- St. Elmo’s fire
- A bright orange glow in the engine inlets
ASH MAY BLOCK PITOT/STATIC SYS SO UNRELIABLE AIRSPEED OR COMPLETE LOSS AIRSPD INDICATION
- False cargo fire warnings
INCREASE CABIN ALT OR LOSS CABIN PRESS
- Shadows cast by the landing lights
- Impaired communications
- Reduction in visibility, or reduction in landing light effectiveness at night
- Abraison on windscreen
- EICAS messages FWD EQPT OVHT or FWD EQPT SMOKE may be displayed
- Do not land at airports effected by volcanic ash. If you do, don’t use max reverse thrust, ash on runway may effect braking, don’t use
windscreen wipers to remove ash, tow to gate, do not use APU, don’t use packs if possible.
- Exit volcanic ash ASAP 180 degree turn
- Oxygen masks On, 100%
- Smoke goggles On (If required)
- Auto-throttle OFF
- Thrust levers CLOSE (Reducing thrust = lower EGT preventing the melting of ash and solidification on turbine nozzles)
- Engine Start Selectors FLT
- Pack Control Selectors BOTH AUTO
- Recirc fans BOTH OFF (increases bleed air extraction by forcing packs to high flow)
- Engine Anti-Ice BOTH ON
- Wing Anti-ice ON (increases bleed air extraction, improves stall margin)
- APU START, then ON
- Flight into known areas of volcanic ash should be avoided
- Difficult to detect at night
- Weather radars are not designed to detect volcanic ash
- Remain on upwind side of volcanic ash
- Review NOTAMS regarding current status of volcanic activity
What are some considerations after flying into volcanic ash?
- Close thrust levers to reduce EGT which will reduce or prevent the melting of ash and the molten solidification on the turbine nozzles
- Start the APU
- Slow start may be misinterpreted as hung start
- Avoid rough control of the thrust lever - engine blades may be corroded by volcanic ash leading to higher fuel flows and EGT
- If visibility is markedly reduced, consider a diversion to an airport where an autoland may be conducted
- Cargo fire indications
- Don’t use pax oxygen unless cabin is uncontrollable
- Monitor airspeed and pitch attitude
- Do not use wiper blades to remove ash
What ATC considerations exist following an ADC failure?
RVSM airspace is FL290 to FL410. A pilot shall promptly inform ATC when one of the two altitude measuring systems is not working.
After that, the Captain shall inform the flight dispatcher. For the B767, altitude data shall be displayed on both altimeters based on air
data from 2 different air data sources
Air-data computer failure in climb
1. After instrument source selector switch pushed, hand over control again to PF (if needed),
2. Check EICAS messages – ENG EEC MODE messages. Do checklist.
3. Considerations - Weather ok, but no longer RVSM with only one ADC remaining.
4. Notify ATC and follow their instruction.
5. Contact Flight Dispatcher.
6. May not be allowed to operate in RVSM (i.e >FL290). May need new flight plan for FL290, fuel required???
7. Destination still possible? Diversion?
8. FL290 only requires an additional 700lbs (compared to planned FL330) so there will be no worries making Kagoshima.
20. If you encountered windshear after V1 but prior to VR, when would you rotate the aircraft? How would you do this?
If windshear is encountered near the normal rotation speed and airspeed suddenly decreases, there may not be sufficient runway left
to accelerate back to normal take-off speed. IF THERE IS INSUFFICIENT RUNWAY TO STOP, initiate a normal rotation at least
2000ft before the end of the runway even if airspeed is low. ENSURE MAXIMUM THRUST IS SET. Higher than normal attitudes may
be required to lift off in the remaining runway
21. How would you know you are 2000ft from the end of the runway on take-off following windshear after V1 but before VR?
2000ft is 610m. On a runway greater than 2400m, the touchdown zone markings immediately prior to the aiming point markers are
located 600 meters from the end of the runway. If you are on the aiming point markers then you are only 400m from the end of the
runway, or 1300ft. If departing at night on a runway longer than 1800m, the runway edge lights will turn yellow at 600m, which is
approx. 2000ft. AIM-J 173
RCLL last 900m alt red and white, last 300m red lights
22. When are the master cautions inhibited?
The master caution lights and aural beeper are inhibited for all cautions from 80kts to 400ft AGL or 20 seconds elapsed time from nose
gear extension. So, if a master caution occurs at 100kts and the take-off is continued, the master caution lights and beeper do not
activate, but the alert message will be displayed. (If prior to 80kts, they are activated and continue to alert and sound)
What is EICAS?
EICAS consolidates engine and subsystem indications and provides a centrally located crew alerting message display. EICAS also
displays status and maintenance information.

- Left and right main tanks: 42,671lbs
- Centre tank (-300ER / F): 84,490lbs
When is monitoring of the emergency frequency 121.500MHz required?
Basically for SAR & loss of comms with ATC (not to be confused with comms loss)
Aircraft should guard 121.500MHz except for an “unavoidable situation”. This may be due to:
- Aircraft are carrying out communications on the other VHF channel
- Cockpit duties do not permit simultaneous guarding of two channels
- Airborne equipment limitations do not permit simultaneous guarding of two channels
41. What items are required to be taken off the aircraft in an evacuation?
Even though crewmembers have to take out emergency articles, they are not absolutely obliged to do so, no matter how tense the
situation. Instead they should concentrate their total efforts towards saving lives. The crew take the following items:
- Captain: Crash axe, megaphone, flash light Mid Cabin Exit
- Co-pilot: Signal kit, flash light FWD Cabin Exit

What altitude is required for fire suppression in the 300BCF?
25,000ft is the altitude where fire suppression is performed effectively
What are the 3 types of hydroplaning?
Is due to standing water on the runway completely lifting the wheel off the runway and being supported by the water. Two conditions
must be present.
The surface must be flooded to a depth, which exceeds the total depth of the runway texture plus the tyre tread. This is called the
critical depth and is usually 3mm. b. The aircraft must be travelling at or above the critical speed, which is the tyre speed at which the
standing inertia or the water is such that water is unable to escape from under the tyre tread.
Is due to a damp surface that does not allow the water to penetrate it the surface below. Only one condition is required – smooth
surface covered by thin film of moisture.
This type of aquaplaning can occur at much lower speeds than dynamic aquaplaning and is normally associated with smooth surface
areas such as the touch down zone where large deposits of rubber may be present.
Reverted rubber skid
Caused when the heat built up due to the friction between the tyre and the water causes the water to boil causing steam, which
reverts the rubber. This process forms a seal and prevents the tyre from contacting the runway.
(standing water is an approximate rainfall of 30mm/hr)

- Crew communication – Standard callouts / briefings & terminology / Standard response to order
- Monitor and crosscheck – Scan pattern / instrument monitor during approach / speed and descent rate during approach / verification
of autothrottle and autopilot / CDU operation
- Workload management – Fly the airplane / use of auto flight system
- Discipline – Professional manner / intentional deviation from SOP’s dangerous / strict discipline to SOP’s

Why does the QRH direct an engine shutdown if an engine fuel leak is suspected?
The NNC leads the crew through steps to determine if the fuel leak is from the strut or the engine area. If an engine fuel leak is
confirmed, the NNC directs the crew to shutdown the affected engine. There are two reasons for the shutdown. The first is to close the
spar valve, which stops the leak. This prevents the loss of fuel, which could result in a low fuel state. The second reason is that the fire
potential is increased when fuel is leaking around the engine. The risk of fire increases further when the thrust reverser is used during
landing. The thrust reverser significantly changes the flow of air around the engine, which can disperse fuel over a wider area.
During fuel jettison, what altitude should ensure fuel evaporation?
Fuel jettison above 4,000 feet AGL ensures complete fuel evaporation
Does the EICAS message TAILSKID indicate a tail strike has occurred?
The EICAS message TAILSKID indicates that the tailskid position disagrees with the landing gear position. Although these alerts may
help determine if a suspected tail strike has occurred, these alerts are not intended as the only verification of an actual tail strike.
What are the three take-off methods?
3 types of take-off method used at ANA & differences
" Normal: Step on brakes, 70%, release breakes, thrust set by 80kts
" Static: Step on brakes, take-off thrust set, release brakes
" Rolling: Without stopping, set 70%, then set take-off thrust
With today’s weather in RORS (RVR300M) what type of take-off method would you use?
" Perhaps a normal take-off method because this allows the engines to stabilise at 70% before starting take-off roll, so
engines will be symmetrical thrust under low vis – reduces chance of asymmetric acceleration and therefore
directional control problems with only 300m RVR.
If you did choose to use a rolling take-off, what is the extra runway allowance required? (100-150ft) Is there a weight
addition to consider?
" Check FPDM

master warning activate immediately
Explain the Inhibits
Condition Engine Start Takeoff Landing
Warning Caution Advisory Communication Communication
Start Eng Start Switch N/G Ext 80kts T/O Thrust T/O Thrust 800’ FCS Cutoff
Finish Idle 20s/400’ 20s/400’ 20s/400’ 20s/400’ 75kts/900’ (GA) N/A
“Except for the occurrence of a hindrance where there is a serious doubt that the airplane can safely fly, it is safer to
continue the takeoff than to reject it from a point near V1”
It is left to the Captain’s best judgement
Other factors to consider…
1. Malfunction that would render airplane unable to fly might be engine failure with thrust loss
2. For other malfunctions in the vicinity of V1, it is safer to continue. Even for EGT exceedance or engine fire, it
would be safer to continue, provided there was no loss of thrust. Any system associated with braking like anti-skid
or tire failure is extremely dangerous re RTO.
3. High speed regime > 80kts, low speed regime <80kts.
Basically, in line with 80 kt inhibit, above this speed, consider calling out malfunction in air.

Describe all of the source transfer switches
Selects source for FD bars and FCC.
The indications for a failure depend on which system has failed. If left or right, related FD bars will disappear and NO LAND 3 will
annunciate on ASA. If centre fails, NO LAND 3 will annunciate, though both Capt and FO FD bars will remain. The autopilot will
disengage though as the related FCC has failed. (FCC drives the autopilot servos). A minimum of 2 FCC’s are required for autopilot
Selects the source for the L/C EFIS SG’s and the L/C FCC’s. Usually, the left FMC drives the L/C FCC’s + SG’s and the right FMC drives
the R FCC + SG. In a failed condition, the R FMC drives the L/C FCC’s and SG and the L FMC drives the right FCC + SG.
If a failure occurs, the LNAV and VNAV FMA’s will have a strike through them, VTK and MAP will appear on the EHSI, the CDU will blank,
“L/R FMC FAILURE” will annunciate on the EICAS and the FD bars will disappear on the related side.
FMC Synch display similar indications to that of an FMC – be careful not to confuse. The main difference is that both CDU’s will still
display relevant information during a synch, unlike a fail condition. (AOR)
The EFIS switch controls the source for the related SG, ILS receiver and RADALT. Usually, left drives left, right drives right and centre is
If either side fails, both EADI and EHSI will go blank. To restore, push EFI switch. If both sides running of centre (dual failure), “INST
SWITCH” message will appear on EICAS – checklist!
Controls the source of the IRS for the L/C SG’s & Capt VSI and FO RDMI. Usually, left drives and L/C SG’s, Capt VSI and FO RDMI
and vice versa. If a failure occurs, ATT, VSI flags will appear, EADI will blank, IRS EICAS messsage, NO LAND 3 and Anti-Skid messages
Controls the source for the Capt primary flight instruments and FO primary flight instruments. (ASI/PRIMARY ALT, AND VSI) So if the associated ADC fails, the
instruments will erroneously display. The ADC automatically switches to reflect the AP in CMD, though this does not apply for the
instrument display, hence the requirement to push the switch.

Enter the full latitude or longitude followed by a dash (not a slash), then the increment chosen for the multiple
waypoints. For example, W060-10 adds waypoints starting at W060 in ten-degree increments. Usually, this entry is
made on top of the active waypoint on the CDU to allow the FMC to calculate a proper sequence
How do you enter a course from present position to be flown in LNAV?
Enter P/PXXX, where XXX is the course. Example P/P150. This course of 150 can then be flown in LNAV
When is the EGT indication inhibited from changing to amber?
The EGT has a maximum continuous limit at 925c. If the EGT reaches the maximum continuous limit, the digital
indication, box, pointer and dial all change colour to amber. However, the EGT indication is inhibited from changing
colour to amber during take-off or go-around for 5 minutes. In effect, the temperature inhibit range would be from
925c to 959c. The red line limit of 960c is never inhibited
Following an autoland, when will the autothrottle disengage?
When the reverse thrust levers are pulled aft to the interlock position
401. What protections are built into the thrust reverser system to prevent inadvertent thrust reverser operation?
Each thrust reverser is automatically protected against unintentional reverse thrust: Pneumatically and
- If an uncommanded thrust reverser movement is sensed, an autostow feature automatically applies
pneumatic pressure to stow the reverser
- An electromechanical lock prevents uncommanded reverser deployment in the event of additional

413. Where will the Vmo pointer and the airspeed pointer position themselves following an associated ADC failure?
The Vmo pointer will position to 260kts when data from the ADC is unreliable. The airspeed pointer indicates zero of
the associated ADC has failed
What non-normal configuration will require the longest runway for landing and why?
All AC buses off Flap 30 landing. This is because auto speedbrake is not available, anti-skid for outboard wheels in
inoperative, and if the hydraulic driven generator equipped, thrust reversers are inoperative
What are the possible indications of an ADC failure?
The following may be present:
- Airspeed indicator MACH flag, AS flag, Vmo pointer at 260kts AIRPSD POINTER ZERO
- Altimeter OFF flag

Can NO AUTOLND or NO LAND 3 be blanked using the push/reset switch of the ASA?
It will depend on whether APP has been pushed as follows:
- Before APP selected: If the condition that caused the fault is still present when the switch is released, the
annunciation will return to NO AUTOLND or NO LAND 3
- After APP is selected: If NO LAND 3 was displayed, the annunciation will blank, and remain blank until
after landing. If NO AUTOLND was displayed, this will remain displayed. You cannot blank NO
425. Will automatic rudder input be provided following an engine failure on a multiple autopilot ILS approach?
AFDS controls rudder during multiple autopilot ILS approaches to compensate for engine out asymmetric conditions
