ELTs
There is much talk of "the ELT" and "how it would go off in a crash".
Can anyone confirm whether all airliners now have crash activated ELTs? Or whether just newer ones do, and the older ones just have ELTs in the cabin / rafts for manual activation?
And if the latter, what about this vintage 777? I have (slight) reason to suspect that this 777 might not have a "fuselage mounted ELT" (i.e. the location / type / crash activated that got the LHR 787), whereas newer 777s do?
