Hi all,
Been scratching my head for a day or two regarding this issue. I know how to do the RNAV approach on the A310. Being properly configured as per the book, P.DES does not want to arm at all on the A300. Unless im doing something really wrong, this seems to be bugged. Just tried the same practice approaches on the A310 and there it works as it should. I also had some frozen V/DEV issues today.
Pleased to hear!
