Recover,
Perhaps you might ponder why your Megaplanes product doesn't know about this 500fpm requirement? My present main type is the only aircraft I have ever flown which would fail an Instrument Rating FLOWN AUTOMATICALLY! It comes from Seattle btw.
Just another dig at the folks over there who don't build very good aircraft! (And the NG speed control algorythms in desent are a disgrace! Thank God I don't have to fly the BBJ!).
