Faulty Aispeed Sensor...???

Posted by Rupert Kent on November 27, 2010 at 8:48am

Hi all,

 

Running some tests on my APM after config and the test -> airspeed is coming back with results similar to the following. Pretty sure my Skyfun isn't doing 20km/s sat on my workbench...! Can anyone shed any light on this...? Is my airspeed sensor faulty...?

 

3732m/s

    Thanks for the fast reply Chris. Yes, blowing on the pitot does generate a stream of values in the CLI. It was the fact that it "measured" 0m/s then suddenly -20km/s then +20km/s Bizarre, but if it's OK, it's OK. I must add, it appeared to work fine on the last flight - I just wanted to make sure it hadn't died on my workbench.

    That's looks pretty normal. The results aren't meaningful on the bench, but you can try blowing into the active pitot tube and see if it generates results, as shown in the manual.
