Hi,
I tried to disable the airspeed_ets offset calculation in initialization. However, it did not work because I think that sensor offset strictly depends on temperature. When I first power on, sensor gives values around 1500. It worked for 15-20, and it came to
its actual offset value of 1550. It was in room so the temperature was constant. I think that the sensor's own temperature has increased because of working.
Considering the temperature variation during long flights, I think that we must calibrate the sensor for temperature variation.
Best regards,
Refik

why we couldn't calibrate it.
