Hi, I'm having an odd interaction between EXP5000 and IFD running 10.2.6.1. After exchanging PFDs due to LCD failure, both units shipped by Avidyne are sending non zero airspeed (IAS and TAS) to the IFD while the aircraft is parked, even with pitot cover on, even if I disconnect the pitot and static lines. The issue is a differential pressure, see attached PFD diagnostic screen. Although the PFD itself suppresses display of airspeeds below 20kts, as soon as the IFD reports a ground speed of zero (ie. gets a GPS lock) the PFD starts showing wind vectors. Any idea if this is a normal or expected behavior? Thanks, Ken   |
