Why? It’s Emergency Locator Transmitter designed to activate in a crash did not send any message.
The absence of this ‘SOS call’ through the international satellite-based COSPAS SARSAT search and rescue programme has made the hunt for the missing plane extremely complicated.
“These beacons can be triggered either manually, or upon impact or when they come into contact with water,” says Milan Cermack, CEO of Swiss company Applied Space Technology and adjunct professor at the International Space University in France and Memorial University in Canada.
“These beacons are equipped with their own batteries and shouldn’t be affected by any sort of power failure in the aircraft. However, once they sink completely, the water blocks the signal transmission. There were cases in the past when a helicopter or an airplane simply sank like a stone and the beacon didn’t have a chance to activate,” says Cermack, who has extensive experience with search and rescue operations ...
