The position error is reported for three different pitot-static systems used in the National Aerospace Laboratory (NAL) Quiet Short Take-Off and Landing (QSTOL) experimental aircraft, ASKA, being determined using only the static pressure error, and assuming that the total pressure error is negligible. It was found that a continuous reference altitude and a correction for pressure propagation lag, realized the determination of the position error during speed and altitude transition. The continuous reference altitude was obtained precisely by the combination of a radar altimeter and an aircraft tracking radar. The ground effect on the position error before touchdown is also reported. In addition, the position error in high angle of attack cases was discussed. The resultant position error correction was used for various analyses of flight test data. Furthermore, it was incorporated into the Digital Air Data Computer to indicate the calibrated airspeed and altitude to the pilots.
