CRASH LOCATOR BEACON
An electronic device attached to the aircraft structure as far aft as practicable in the fuselage, or in the tail surface, in such a manner that damage to the beacon will be minimized in the event of crash impact. It may be automatically ejectable or be permanently mounted. If it is automatically ejectable it will also have provision for manual removal and operation. The beacon operates from its own power source on 121.5 MHz and/or 243 MHz preferably on both emergency frequencies, transmitting a distictive downward swept audio tone for homing purposes, and is designed to function without human action after an accident.
