Ledsled,
Every glass cockpit aircraft that I have flown has the RA command on the FDH/ADI/ EADI/name of choice command bars.
Is that so?
From some reasonably current FCOMs:
717:
FD bars disappear during RA
737:
Note: Do not use flight director commands until clear of conflict.
767:
The flight director is not affected by TCAS guidance. Therefore, when complying with an RA, flight director commands may be followed only if they result in a vertical speed that satisfies the RA command.
777:
Note: Do not use flight director commands (integrated cue)/flight director pitch commands (split cue) until clear of conflict.
Airbus:
I believe FDs are to be turned off during an RA.
That's progress, Eh?
