┗━━━━━━━━━━━━━━━━┻━━━━━━━━━━━━━━━━┻━━━━━┻━━━━━┛
Two completely different flight director modes are available, each with its own
characteristic symbols. The symbol displayed corresponds to the basic operating reference
the pilot has selected - either HDG V/S or TRK FPA.
In normal operation PFD1 displays FD1 orders.
If FD1 fails, PFD1 automatically displays FD2 orders, and on the PFD1 the FD2 indication
in the right column of the FMA flashes for a few seconds.
The same applies for FD2 orders normally displayed on PFD2.
IF THE CREW HAS SELECTED HDG V/S TO BE THE BASIC REFERENCE
The PFD displays pitch and roll bars in green. They automatically move out of view at
touchdown in ROLL OUT mode.
They flash for 10 seconds and then remain steady in the following conditions :
- reversion to the HDG V/S basic mode (manual or automatic), or
- change of selected flight level when ALT CAPTURE mode is engaged, or
- loss of LOC or G/S in LAND mode or loss of LAND mode, or
- at the first AP or FD engagement.
The PFD displays a yaw bar in green below 30 feet radio altitude if a Iocalizer signal is
available:
0
during takeoff (in RWY mode)
upon landing (in FLARE and ROLL OUT mode)
