    Ophir Corporation’s Laser Radar Air Data System (LRADS) offers an augmentation or replacement of conventional air data sensors providing all weather performance, enhanced safety and reliability, potential reduction of aircraft program costs and operator’s life cycle costs. Airdata quantities are needed for a multitude of tasks, including flight safety, control, navigation, weapons delivery, flight test, and flight research. These quantities generally need to be measured and then calibrated to remove errors. The techniques and procedures have been only.

RECENT TEST RESULTS OF OPTICAL SYSTEMS The systems used in the flight-test programs de-scribed here were designed to evaluate and demon-strate new airdata measurement concepts. For this reason, the hardware comprising each system was substantially larger than would be the case for an operational system for a high-performance : Rodney K.

Bogue. Recent Flight-Test Results of Optical Airdata Techniques Optical techniques for measuring airdata parameters have been demonstrated with promising results on high-performance fighter aircraft. These systems can measure the airspeed vector, and some are not as dependent on special in-flight calibration processes as current : Rodney K.

The development resulted in a first test system of a future generation stand-by instrument for commercial aircraft. This system has no probes protruding in the air contrary to traditional pitot-static air data systems.

INTRODUCTION Airdata are vital to successfully complete an aircraft’s mission and are derived from the air surrounding the aircraft. References supply pertinent information regarding airdata measurement and calibration. These airdata encompass indicated and true airspeed, pressure altitude, ambient air temperature.

Wind profile data were gathered at altitudes from 3, to 67, ft ( to 20, m), Mach numbers from to 2, angles of attack from 0** to 12", and angles.

The Molecular Optical Air Data System (MOADS) is a compact instrument designed to measure aircraft airspeed as well as the density of the air surrounding the aircraft.

Analysis of Flight Test Results of the Optical Ice Detector Cloud phase discrimination, coupled with measurements of liquid water content (LWC) and ice water content (IWC) as well as the detection and discrimination of supercooled large droplets (SLD), are of primary importance in aviation safety due to several high-profile incidents Cited by: 1.

We present the results of recent flight tests of a prototype Optical Ice Detector (OID) intended to meet the need for cognizance of hazardous flight conditions beyond those specified in Appendix C. Previous flight tests of a prototype OID demonstrated the capability of distinguishing liquid water clouds from ice clouds.
