Jittery or jerky airspeed indicator

Featured Replies

I'm experiencing a jittery or jerky airspeed indicator. The needle jumps back and forth. It could be at 140, then in an instant it's 150, then 140, then 145 all happening in 2-3 seconds. This happens while the plane is on the air. It is almost impossible to land. What is causing that and how is it fixed? 

Everything else seem to be running fine. All the other dials run smoothly.  And there is no shimmering on the panel and the instrument are clear or not blurry. I have FPS set to unlimited and framerate runs at about 25-30 FPS on average. Thank you.

Software: latest Windows 10 Pro, P3Dv4.5+, FSX Steam, and lots of addons (100+ mostly Orbx stuff).

You can try turning off weather to see if wind gusts are an issue, and also make sure pitot heat is on. Other than that I have no idea what on your setup could be causing that problem.

You were right. I changed from "fair weather" to "clear skies" and the airspeed indicator stopped jumping around. (I had pitot heat on). Thank you, Al,
