AFCS Flashcards
When does the aFCS initially engage the yaw damper?
Automatically when a Remove Electronics Unit (ERU) and two sources of roll and yaw are available (IRS)
What is the maximum altitude for flight with the yaw damper disengaged?
41,000 ft
What will happen if the YD is disengaged with the AP engaged?
AP will disengage
What is the minimum height at which the autopilot can be engaged?
400 ft AGL
What is the minimum height that the autopilot can be used during a CAT I or CAT II precision approach (ILS)?
Category I or II ILS: 80 AGL
What is the minimum height that the autopilot can be used during a non-precision approach with no vertical guidance?
400 ft AGL
What is the minimum height that the autopilot can be used for a non-precision approach with vertical path reference?
160 ft AGL
What is the speed limitation for FLC mode use?
Above .85 M is prohibited
When must both STALL PUSHER switches be on?
For duration of the flight
What are the four purposes of the MSTR DISC push button on the control wheel?
- Disconnects the autopilot,
- Silences a disconnect aural,
- Interrupts pitch trim while held,
- Inhibits the stick pusher while held (non-EASA a/c)
What will cause manual disengagement of the autopilot?
Pressing the AP push button, pressing either MSTR DISC push button, manual trim activation, pressing the YD switch on the FCP, physical override of the AP servos (not recommended)
What will cause automatic disengagement of the autopilot?
Unusual attitude, stall warning activation, activation of wind shear avoidance (2-sec delay)
What is the purpose of the touch control steering (TCS) button?
Momentarily overrides the autopilot and sync FPA, speed or VS value
What will happen in the event the master AFCS/AT fails?
Standby AFCS/AT automatically takes over and the FD modes will revert to basic ROLL and FPA
How is the aster AFCS identified?
FCP indicator lights adjacent to the YD and AP buttons
How is the AFCS 1 manually selected to AFCS 2?
Selecting the AFCS 1/2 switch on the reversion switch panel (RSP)
Does the indicator light on the flight control panel (FCP) indicate that the associated mode is currently active?
No. The pilot must confirm mode status or operation from the flight mode annunciation (FMA) on the PFD
How are active/armed flight director and auto throttle modes indicated on the FMA?
Active shows in green, armed shows in white
How does the autopilot engage if no vertical or lateral flight director modes are armed?
Basic ROLL and FPA modes
