Refer to figure.
The attached figure shows a Multifunction Display (MFD) with AFCS controls and Flight Mode Annunciator (FMA). The pilot is performing a commercial air transport VFR flight and the passengers asked to deviate from the planned route. The pilot disengages the autopilot, turns off course and descends to a lower altitude. The Flight Director (FD) at this point indicates that the aircraft is NOT following the planned route. Should the pilot take further action?
  • A
    No, the FMAs will automatically be removed from view and the FD command bar will be centred after a short period of time, unless the pilot returns to the planned route.
  • B
    Yes, the FD must either be switched OFF or the pilot must select modes and parameters for the new intended flight path for the FD to give appropriate guidance.
  • C
    No, the FD will remain ON and automatically change modes to show appropriate guidance for manual flight during the entire time the autopilot remains disengaged.
  • D
    Yes, the autopilot is still engaged and must be disengaged, because the FD indicates that the aeroplane is turning right and climbing to the selected altitude of 3000 ft.

Refer to figure.
The Flight Director (FD) displays guidance commands from the Flight Management and Guidance Computer (FMGC) on the Primary Flight Display (PFD).

The flight crew may manually fly the aircraft, following FMGC guidance commands, or crosscheck the FMGC orders when the autopilot is engaged.

When manually flying the aircraft with FDs ON, the FD bars on the PFD symbol provide lateral and vertical orders in accordance with the active modes that the flight crew selects.

- Fly with a centred FD (by selecting different modes or parameters).
- If not using FD orders, turn the FD off.
