Actually I have experienced the same thing with certain aircraft like the CLS A330/340 series, PSS 777, and the QW 757. Typically this situation
involves Active Sky Advaned or AS Enhanced. I usually switch the pitot heat off and on again when the airspeed tape goes to zero, switch off AP and
AT, reduce throttle and hand fly the aircraft to maintain course until the airspeed comes alive again. I know this is a AS problem, as I have cleared
the wx via FSUIPC, shut down ASE and performed a flight without ASE running. No airspeed issues at all. Every once in a while the airspeed problem
creeps in shortly after takeoff...before reaching the first waypoint, but most of the time it happens when I'm climbing through FL250. Yet, I never
have this problem with the PMDG aircraft.
