Which statement concerning the use of the Autopilot system is correct ?
Without Land 2 or Land 3 annunciated the autopilot must be disengaged below 100’
What are the FIVE Autothrottle modes ?
SPD THR THR REF IDLE HOLD
AT Mode SPD ?
AT applies thrust to maintain window speed or FMC speed within the limits of the current Ref Thrust
AT Mode THR ?
AT applies thrust to maintain Climb/ Descent commanded by the Pitch Mode
AT mode THR REF
AT applies thrust to maintain Ref thrust displayed on EICAS
AT mode HOLD
AT servos no longer operating. Thrust can be manually set
AT mode IDLE
Displays as AT moves TLs to idle. IDLE mode is followed by HOLD
Name the 9 ROLL MODES
LNAV HDG TRK ATT LOC FAC B/CRS ROLLOUT (TOGA)
How is LNAV disengaged ?
LNAV is deactivated by selecting any other roll mode or by disengaging the autopilot and turning both flight directors off
Describe the Roll Mode ATT
ATT – (active) – When the autopilot is first engaged or the flight director is first turned on in flight, the AFDS holds a bank angle between 5º and 30º and does not roll to wings level. When the bank angle is less than 5º, the AFDS returns to wings level (HDG HOLD or TRK HOLD). When the bank angle is greater than 30º, the AFDS returns to 30º of bank.
When is the Roll mode ROLL OUT activated
ROLLOUT (armed) – Displayed below 1500 feet radio altitude and activates at touchdown with weight on the wheels
Describe the Roll Mode FAC
FAC (armed) – AFDS captures the IAN final approach course
FAC (active) – AFDS tracks the IAN final approach course along the inbound bearing
Name the nine PITCH MODES
TOGA VNAV - VNAV SPD / VNAV PTH / VNAV ALT V/S FPA FLCH SPD ALT GS GP FLARE
For what functions does the Altitude displayed in the MCP window provide a reference ?
ALTITUDE ALERT AND LEVEL OFF
