Request for Plane blocked airspeed crash logs

I’d like to get any dataflash logs people don’t mind sharing that have blocked airspeed sensors, particularly if it was bad enough to result in a crash. I’m looking at the management/detection of blocked airspeed sensors, but without more logs it’s hard to be confident in a lot of solutions I can push.

Any logs and information about the setup and what happened from the users perspective would be great.

Thanks for your time.


Hey, not sure if this is helpful, but I had one today. (No crash, thankfully)

After seeing very poor flying performance, I found 2 issues:

  1. The pitot tube ram-port was blocked
  2. The (blocked) ram port was also vented (via a T-junction) to atmospheric pressure INSIDE the plane. This was a mistake, as I hoped the port’s static pressure would be also vented to atmospheric inside the plane… so I think you’ll see unintelligible noise from the airspeed sensor.

Let me know if you want more details? Thanks for all your work!
