Q
  1. Automatic auto throttle engagement (autothrottle wake up) can occur in all flight control modes but will not be supported under which pitch modes or flight conditions?
A

10.
Pitch mode is FLCH or TO/GA.
Airplane below 400 feet AFE on takeoff.
Airplane below 100 feet RA on approach.
During a descent in VNAV SPD, the autothrottle may be in HOLD and will not support stall protection

Q
  1. Pilot inputs → ACEs → Control Surfaces is the signal sequence for the Direct Flight Control Mode. The aircraft can enter the Direct Mode as a result of _______.
A
  1. The ACE’s automatically transition to the direct mode when they detect a Failure of all three PFCs or lose communication with the PFC
    Manually by placing the PRIMARY FLIGHT COMPUTERS switch to DISC
17
Q
  1. In what flight control mode(s) are the following not available: automatic pitch compensation for thrust changes, gear configuration changes, turbulence, flap changes, speed brake configuration changes, and turns?
A
  1. Secondary and Direct flight control modes do not provide automatic pitch compensation.
18
Q
  1. In Secondary and Direct flight control modes, the elevator feel system provides two force levels that change with ________.
A
  1. Flap position
19
Q
  1. In the Secondary and Direct flight control modes, spoilers _______ are locked out as speed brakes.
A
  1. 4, 5, 10 and 11
20
Q
  1. To protect against inadvertent deployment during cruise, when is flap and slat extension from the UP position inhibited?
A
  1. At speeds greater than 250 knots (200A), 265 knots (200B/C), 275 knots (322), and at altitudes above approximately 20,000 feet
21
Q
  1. In the primary flap mode, the flap load relief system protects the flap from air load damage. If placarded flap airspeed limits are exceeded with the flaps in the _____ through _______ position, the flaps automatically retract to a position commensurate with airspeed.
A
  1. 15, 30
22
Q
  1. Slat load relief is available in the secondary flap mode because slats are fully extended in all flap positions in the secondary flap mode. If airspeed exceeds _____ knots (200B/C) or ______ knots (200A), or _____ knots (322), the slats retract to mid position.
A
  1. 239, 215, 256
23
Q
  1. In the secondary flap mode, the flaps and slats are positioned by electric motors, and movement is considerably slower than primary mode. Because autoslats are unavailable, the slats are _____ extended at the flaps ______ through ______ detents.
A
  1. Fully, 1, 30
24
Q
  1. The alternate flap mode must be manually selected. The alternate flap mode allows direct manual operation of the flaps and slats through the ________.
A
  1. Secondary drive electric motors.
25
Q
  1. Alternate mode flaps and slat extension is limited to slats mid and Flaps 20. What is not available in the alternate mode?
