AOR Flashcards

What is “Go-mindedness”?
The idea of go-mindedness is that except for the occurrence of a problem or hindrance, where
there is a serious doubt that the airplane can fly safely, it is safer to continue the take-off than to
reject it from a point near V1.
Notes on Go-mindedness:
- Decision is left to the Captain’s best judgement
- Engine failure with thrust loss, or a take-off warning, that would render the airplane unflyable
prior to V1 should be rejected
- Over EGT or engine fire without thrust loss near V1 should be continued (PIC)
- Malfunctions such as tire or anti-skid failure can hinder braking performance during an RTO
What is the RTO policy of calling out any malfunction during the take-off roll?
The crewmember recognising a malfunction before V1, DEEMING THE TAKEOFF SHOULD BE
REJECTED, shall call it out clearly. Although callout for all other malfunctions shall be left to the
crewmember’s judgement depending on circumstances, care should be taken for not causing an
unnecessary high-speed RTO. In the case of engine failure, it is enough to call out only “Engine
Failure” without mentioning the engine number
What is the minimum amount of braking required during an RTO if there is a failure of the RTO
braking system?
If the autobrakes become inoperative or disengaged during RTO, MAXIMUM manual braking
must be applied, until the airplane is sufficiently decelerated
Can reverse thrust be used on an RTO following an engine fire indication?
Yes, in order to establish the maximum deceleration configuration at the earliest, use all reversers
even where there is an engine fire warning
When should the V1 call be made?
The PM should initiate the V1 callout as the airspeed needle is observed within 5kts of V1 speed,
and complete the callout by V1
Who has control of the aircraft during an RTO?
When the Captain decides to reject a take-off, he will call “Reject”, assume control and initiate the
procedure, while the Co-pilot shifts to perform the PM duty. The call of “Reject” should also be
interpreted as “I have control”
Following a “Go” decision, until when are the thrust levers the Captain’s area of responsibility?
The thrust levers are the Captain’s area of responsibility until the landing gear lever is placed to
UP
What are some considerations following an RTO?
The following should be noted following an RTO:
- Necessity of passenger evacuation
- Passenger notification (PA)
- Necessity of brake cooling
- Use of parking brakes
- Risk of tire burst with ground crew in the vicinity
- Necessity for brake energy calculation prior to another attempted take-off
An RTO executed at V1 + 4kts will cross the threshold at what speed?
65kts
Explain the required V1 take-off performance standard:
Take-off performance requires that the airplane will be able to attain a height of 35ft over the end
of the runway when an engine failure occurs before V1 (VEF) and the take-off is continued. Take-off
performance standard also requires that the airplane will be able to stop on the runway without using
reverse thrust when an RTO is initiated at V1
What is the “Balanced field length concept”?
V1 is selected in order so that the accelerate stop distance is equal to the take-off distance
How should the initiation of a non-normal procedure be made?
Do not start the procedure by reflex reaction even if the specified checklist includes some
memory items. The Captain must first verify the condition, then select an appropriate procedure
according to the flight situation and decide whether to take over the PF duty. Then the Captain shall
command the required non-normal procedure at the right time
Describe the basic PF and PM task assignment during a non-normal procedure:
It is basically designed so that PM takes charge of all the operations except for those directly
related to vertical / lateral navigation (such as special escape procedure / rapid depress manoeuver /
requirement to enter the holding pattern etc.) When the Captain instructs to commence a nonnormal
procedure, the PF works on the future flight plan (route of flight)
What are the confirmed action switches and how are these performed?
In non-normal procedures, confirmed actions are established and the crewmember shall carry out
his procedure only after confirmation by the other crewmember. The listed confirmed actions are
those that are hard to recover or irreversible, but do not apply during the DUAL ENGINE FAILURE
checklist, such as:
- Engine fire switch
- APU fire switch
- Cargo fire arm switch (NOT the discharge switch)
- Generator drive disconnect switch
- Engine shutdown (i.e. fuel control switch)
Is a wind correction required during autothrottle use?
No, because the autothrottle automatically adjusts thrust for any wind speed changes at varying
altitude along the approach path, however a 5kt tolerance is added
Why is a wind correction to target approach speed required?
Generally, wind speed is lower closer to the ground surface so airspeed decreases during
approach in a headwind, possibly leading to a short touchdown
What is the wind correction on target approach speed formula?
Basic target approach speed is BUG + (1/2 Headwind + Gust)
When should the wind correction on target approach speed be held until?
The nearer the aircraft approaches the threshold; the less important it becomes to maintain the ½
head wind speed additive to prevent a short landing. When passing through the threshold, airspeed
of BUG + Gust will be appropriate. Due to landing performance, unnecessary speed additive should
be eliminated, gradually and not forcibly during approach
What target approach speed is used when wind is reported as calm?
BUG + 5 is used
Can the engine pod ever scrape the runway with a nose-up attitude?
No, nose down attitude must be greater than minus 1, and roll angle must be 12 degrees or
greater
Which parts of the aircraft are suspect to ground contact during inappropriate landing pitch and
roll values?
The following parts of the aircraft may make contact with the ground:
- Nose gear
- Engine nacelle
- Leading edge slat
- Wing tip
- Elevator
- Tailskid
- Aft body
At what pitch angle is there a possibility of tail contact on landing?
In the case of main gear struts extended, there is a possibility of tail contact at a pitch angle of 9.5
degrees, when roll is zero. In case of main gear compressed, the ground clearance decreases, and
the margin of pitch angle decreases by approx. 2 degrees to 7.5 degrees nose up
What is the definition of “standard callouts”?
Standard callouts are the minimum required callouts relating to the following items, and exclude
callouts that instruct specific operation (i.e. Gear Up / V1):
- Altitude / Position / Speed
- Significant deviation in flight path / speed / descent rate
- Information to aid judgement for making a landing or missed approach
- Flight and navigation instruments / autopilot system status
What are the main objectives of standard callouts?
They are:
- To confirm information on altitude, position, speed and system status
- To enhance crew coordination, common recognition, and fail safe function
