Autoflight Flashcards
When will the FGCS automatically select half-bank? What is the bank angle?
- FL250
- 17 degrees
What is FPA?
Flight path angle is a pilot selectable pitch attitude of climb or descent. FGCS adjusts thrust to maintain pitch angle and airspeed
What does the TOGA button do?
Ground: Activates TO guidance crossbars
In flight: Activates GA guidance
What do the TO guidance crossbars do?
Maintain extended runway centerline
Maintain pitch guidance according to slap/flap setting
What is the TOGA mode deactivated?
Another vertical mode is selected
Autopilot is activated
TCS button is pressed
When will the FD automatically display?
TOGA button pressed
Autopilot is activated
Windshear detection
What is the function of the TCS button?
Allows manual override of the autopilot
When released, airplane maintains new altitude (if in ALT mode) but will return to previous lateral mode
(will recapture GS if on ILS)
What will disengage the autopilot?
AP button on GP is pushed Any manual pitch trim activated Either AP/TRIM DISC button is pushed Stick shaker activated Flight controls in direct mode Aileron or elevator controls disconnected Overpowering the yoke Internal system failures
Can the yaw damp be deactivated if the autopilot is on?
Yes
When will the auto-throttles engage?
Ground: AT TO is armed and TLA > 50 deg
Flight: AT is armed and airplane > 400ft AGL
Will the auto-throttles compensate for gusty wind conditions?
Yes, up to 5 kts
What will disengage the auto-throttles?
AT (TL or GP) is pushed
TLA difference > 8 deg
TL at idle with WoW or wheels spinning
Internal system failure
What is SPDe? What mode uses SPDe?
Speed on elevator, thrust is fixed and pitch is adjusted to maintain airspeed (VS changes)
FLCH uses SPDe for climbs and descents
What is SPDt? What mode uses SPDt?
Speed on thrust, thrust is adjusted to maintain selected airspeed
FPA, VS, GS, ALT, ASEL
What are the AT modes?
SPDe, SPDt, TO, GA, HOLD, RETARD
