Hello all..
For the past couple of week, as soon as I start my Xtreme in the plane and the engine oFF
It shows 18MPH and i'm definitely not moving

In the air it shows the same speed than my Challenger.

Hi,

Did you zero the airspeed indication when on the ground and no wind blowing?

Regards.

I did when I installed it but I guess I will have to do it again.
Thx
