Ugly, Awful Frame rate on PFD

I’m working on in civil aviation. I flew in the cockpit of many aircraft like A320 B737 and my virtual pilot. Everything was going well when you decided to build a drone, but until I see the PFD… it frames (movment) very badly. All parameters move too much.

All parameters and animations (like speed, alt change) in a real airplane are smooth (like this video) PFD is better when connected via usb, but the parameters are very bouncing… everything gets worse when connected wirelessly. I know how wireless systems work packet frequency is slow so the screen looks like 5fps… But please add an animation to it so you can fill in the number of frames in between. I’m begging you, I get sick every time I see. @rmackay9 @iampete

Well, it is not that easy. The update of PFD (HUD) is data driven, if the data comes in slowly then the update rate is slow as well. Adding animation adds delay to the display as well, and adds a lot of unnecessary load to the gcs computer.
Extrapolating is a possible solution, but this can lead to displaying invalid data, and even bigger jumps.

Real airplane displays are smooth because they got in a high rate.

If you have a good telemetry link then you can increase data rate, and get fluid update rate.
