At the time our new HPS-1 Heated Pitot-Static Probe is thoroughly tested in our wind-tunnel. We use an IR-camera to make sure that even at high airspeed and high angle of attack the tip is heated uniformly. Furthermore we measure the power as a function of airspeed and check heater-control...

There are two important effects if you measure temperature on an aircraft:

  1. At low airspeed, when the heat exchange between the air and the temperature sensor is low, the temperature error is dominated by radiation (e.g. sun heating up the sensor) and the heat transfer between the body of the...
