Airspeed Sensor Issues?

On a recent flight (fixed-wing aircraft) I noticed that the difference between the airspeed and ground speed was as much as 20+ mph when at the same time the indicated wind speed was just under 7 mph.  How can this be and is this most likely and issue with the airspeed sensor, GPS, or some other reason I am overlooking?

  • I am still having the same +20 mph issue myself, did this turn out to be a heat problem?
  • Did you followed the instructions  Calibrating an Airspeed Sensor ?

    Important part: After you start up APM on your aircraft you should wait at least 1 minute for your electronics to warm up, preferably longer, and then do a pre-flight calibration of your airspeed sensor.

    Sensor is drifting quite allot if it heats up, so maybe worth to check if it improves your airspeed accuracy.
