Abstract : The gross system parameters for post-1975 Search and Rescue (SAR) avionics equipment were developed through a synthesis procedure that combined the results of surveys conducted with personnel engaged in various phases of SAR activities, a statistical investigation of SAR operations, and knowledge of the state of present and developing technology. One of the major conclusions reached was that the gross system parameters must be specified with respect to lowering the probability that the total SAR mission time will exceed two hours. Recommended parameters applicable to a system serving both combat and noncombat military SAR missions as well as civilian SAR missions included: a continuous world-wide distress monitoring system operating on 121.5 MHz and providing one- to two-mile position accuracy, a homing beacon with a 25-mile range operating on 121.5 MHz, and automatic activation of the signaling device(s). Additional features required for combat SAR missions included: voice communications on 243 MHz, non0voice identification capability, and covert signaling facility. The primary design emphasis for personal equipment should be placed upon reliability and ease of operation. (Author)
