Method and device to help locate an aircraft wreck submerged in an expanse of sea water.

摘要

The device has floating beacons (2a, 2b) e.g. underwater locator beacons or emergency locator transmitter beacons, to emit signals (15A, 15B) e.g. underwater or emergency signals, to be detected remotely. An ejection unit automatically ejects the beacons out of a fuselage of an aircraft (AC), during immersion of the aircraft. A triggering unit automatically triggers the emission of the signals after the ejection. The beacon is provided with an auxiliary unit to allow aiding in localization of the beacons, when the beacons float at a surface (S) of a sea water expanse (M). The auxiliary unit is chosen from a group comprising dye type marker, smoke generator and global positioning system type auxiliary beacon. An independent claim is also included for a method for aiding localization of a wreck of an aircraft submerged in a sea water expanse.
