The Pacer Systems Inc. low-range airspeed system LORAS 1000 was evaluated on a helicopter by the United States Army Aviation Engineering Flight Activity at Edwards Air Force Base, California, in February and March 1976. Properly calibrated and aligned, the LORAS 1000 accurately displays low airspeeds along the longitudinal and lateral axes. When located above the rotor hub resultant airspeed is also displayed. In forward and rearward flight the system output was linear except for small discontinuities at -10 and 10 knots true airspeed KTAS. The system output was repeatable for the range tested 31 KTAS rearward to 122 KTAS forward. The density altitude displayed values were accurate for the range tested. No reliability or maintainability problems were encountered.
