Additional information

The DLR Falcon is equipped with a 1.8 m noseboom which carries a 5-hole flow angle sensor connected to a suite of pressure sensors in a thermally controlled box in the aircraft nose. The system measures static and impact pressure as well as the flow angles which are used to calculate the 3-dim. wind vector with high accuracy and temporal resolution. The system is regulary used for turbulence measurements.

The system has been extensively calibrated in flight to determine the aircraft induced pressure error (static source error) using the trailing cone technique.
