Why does airspeed drop to zero suddenly? Help!

Featured Replies

This has been happening regularily in FSX using ASX or REX..Flying along all of a sudden my ASI will drop to zero even though I am still at normal cruise speed. The only way to get it to display again correctly is to reload the aircraft. Then it drops again a few minutes later:( This only happens using an add-on weather program.Any ideas how to cure it?ThanksTrafficPilot

Try putting on the pitot heat and see if that doesn't fix it.

Thanks guys will give it a go! :(

Sounds like a frozen pitot. Switch on pitot heat/anti-ice.

Very Funny, you want realism, and when you get realism, you cant handle the truth :( . Things Freeze in cold weather LOL.I used to get this problem, and i think it is from ASA/ASX. I think there is option to disable freezing in ASA/ASX. The effect, if using auto throttle is extreme overspeed cause the autopilot thinks speed is zero all the time.But in cold areas i just put on all the anti ice and pitot heat and it fixes the problem.

Embarrassing! :( I forgot pitot freezing was modelled oops. Maybe I should refer to the checklist more often!
