Emergency Locator Transmitter
Hello and at outset , I need to say I am not an aviation professional. I would be grateful, if someone can succinctly explain to those of us non professionals, how the ELT would work, with reference to the B 777.
i.e.
Where is it located?
What triggers it ?
In the case of ocean crash, as the AC or its debris sinks, does the ELT detach and float ? If so, how does it detach ? E.g. is it a solenoid like mechanism etc.
What is the ELT signal ? Is it low frequency or high frequency ?
What position information does it give ? Or is there no position signal, and one needs to use triangulation to find it?
Any other info would be great. Thank you in advance.
