A320 ADR dual fault
Hi guys, as usual thanks for you help.
If I have a failure of 2 ADR, the flight directors are still useable? or is there anything preventing me from doing that?

Hi there,
You cannot use F/D in either case ADR 1+2, 1+3 or 2+3. However you can also go back to Track/FPA and use the "bird" that should be good enough to fly raw data.
Hope that helps.
cheers.

You will have to go back to basis: ATT and Power.

bird and track index
Somebody could explain me if the track index (blue line over the bird) will be displayed in the PFD (to help during ILS raw data) in case of dual ADR fault. Thanks

Any time you have a failure where the flight directors disappear (i.e. Dual ADR Fault etc), there will be a red "FD" box on the PFD. It's often overlooked in the heat of the moment, but if you deselect the flight director, this will give you the blue track line.
In conjunction with TRK-FPA, this at least gives you a track target to fly.
