    Make sure the sensor is really working when you connect it to your flight controller (try blowing into the pitot tube, you will see the changes in value of Air sped reading in mission planner, usually above 15m/s). Calibrate the air speed sensor properly. Then you can use it on cruise, fbwB, RTL, auto takeoff and auto land.

    This is analog air speed sensor. I tried using that, but I find the calibration very erratic. So I replaced mine with digital air speed sensor (white instead of black differential air pressure sensor), it's more expensive but more reliable
