FLIGHT TEST EVALUATION OF THE FLUSH-MOUNTED, TUMBLING-AIRFOIL, CRASH POSITION INDICATOR,

Abstract

The suitability of the crash position indicator (CPI) was analyzed in terms of its ruggedness, reliability, and capability to meet the operational requirements for transmitting a radio signal after successful deployment during aircraft crash impact. The general reliability and ruggedness of the beacon to survive ejection and impact was adequately demonstrated during six ejections. The following problem areas were observed: (a) Inadvertent ejections of the beacon occurred twice. These ejections were attributed to excessive sensitivity of ejection initiators. (b) Failure of the CPI to transmit occurred four times during this test. (c) Fine tuning of the SARAH receiver was considered more difficult than necessary because of the short 3-sec 'on' time as compared to the long 5-sec 'off' time. F3ight tests of the beacon demonstrated the suitability of its employment after aircraft crash impact. (Author)
