Autoflight system Flashcards
Auto flight systems are
FD
AP
A THRUST
MCDU take FMS data
Flt plan entry
Performance vertical planning
What has priority selected or managed guidance
Selected
Auto pilot limitation
Alt and time
100’
5 sec
During an ILS APPROACH YOU CAN ENGAGE BOTH_____
AP
What will
Cause AP to disengage?
When normal law and any protections are exceeded
When Alpha protection is active
When both TRs are set above FLEX/MCT and aircraft is on the ground
If both FMGCs fail the _______ is inop
Auto thrust
Modes of auto thrust are
Fixed and variable
Fixed-during climb and descent
Variable- (speed or mac on PFD) climb and descent when a specific rate is being maintained/ alt being captured/ level flight/all flight guidance is off but auto Thrust is still
Active
Thrust Lock display is Not normal for auto thrust it will display if _______
The red button is pushed or there is a fault in the system.
Alpha floor is auto thrust feature to help recover from_______
It can happen even if auto thrust is not engaged
High angles of attack and low airspeed situations
Alpha floor may engage during wind shear recoveries
Vapp adds 1/3 of steady state winds with a _______kt min
5
Green dot is the ______
Min speed in clean configuration
In managed speed the aircraft slows to this when approach is activated
When Flaps 1 selected speed slows to _______speed. Maneuvering speed with slats extended
When Flaps 2 is selected the aircraft slows to _____speed. Which in maneuvering speed with flaps 2 or 3
When flaps full is selected aircraft slows to _______
S
F
Vapp
Ground speed mini protects agains wind shear. It is calculated by subtracting runway headwind from Vapp
No direct indication of ground speed mini. Except if Vapp magenta triangle moves up to protect for winds.
EXPED button will climb at ________dot but should not be used above 250’
EXPED button will
Descend at______
Green
340kts or .80 thrust will be idle
