Absolute Altimeters

reportActive / Technical Report | Accession Number: ADA131746 | Open PDF

Abstract:

This test operations procedure TOP delineates general test and specific subtest procedure required to determine the technical performance of absolute altimeters. Absolute altimeters which are used to measure vertical separation between the aircraft and the surface of the earth , may also be referred to as Radio or Radar altimeters as they determine absolute terrain clearance by measuring the time interval required for a radio frequency signal to travel from the aircraft to the terrain and back again. The TOP is limited to the listed tests which are applicable only to absolute altimeters. The tests will determine Warm-up-Time Primary Voltage Sensitivity Mutual Interference Low Altitude Accuracy and Resolution Failsafe, Pitch and Roll Accuracy and Range Terrain Tracking Performance in adverse weather over icecaps and snow, and under continuous operation.
