A320 loses speed during open climb

Post by A320-Simmer »

Hi!
I'm trying several models to find the best one - and it seems the PA A320 is the one ;-) - as a flight model for my AST-based homecockpit (airsimtech.eu).
It works fine so far, but unfortunately the open climb mode makes troubles: From more or less 25000 ft to the cruising altitude the aircraft suddenly increases the climb rate and loses its target speed selected in the FCU - so you are forced to switch over to V/S selection to avoid stall. Up to this altitude the open climb mode works fine. Also the open descend mode is no problem. I'm using the FBW from Gary with all PA models from A319 to A321.
Do you have any idea what causes this strange behavior?

Many thanks in advance,
Christoph

It shouldn't be caused by my gauge. Have you tried it with out it?

Hi Gary!
Just tried without your gauge - the same problem of losing speed. The flight model of the Airbus X makes the same problem - strange...

Best regards,
Christoph

Hi Christoph, most likely it's gravity pulling you downwards. Try Mars or some other planet.
