Well, that isn't entirely true anymore. With CPDLC, which most companies have nowadays, it is done electronically via satellite.
Not all airplanes are CPDLC equipped. And not all regions are CPDLc capable Inmarsat does not cover the artic routes.
If one needs voice communications.
I will take your word for the time frame.
Point 1: That is IF the pilots have time to activate the ELT while inflight. And that is not a normal procedure.
How long it takes to set a switch? On the B777 there is Master Caution system that can activate the ELT. And of course is not a normal procedure, it is an emergency procedure.
Point 2: I will take your word, again, on the timeframe, but I doubt the mission can get organized that fast.
It depends on the nearest country. I heard that the US Coast Guard is quicker than the Haitian patrol.
Again, that isn't a normally accepted procedure. Not saying it can't or shouldn't be done.
What would you have done instead to expedite rescue?
Sure, but the range at which they can be received is limited.
An airliner at 40,000 feet can hear an ELT 100nm away. When you get handover from NY Radio on HF to San Juan Radio on VHF distance is over 300nm.
So have I. I have told you what MY qualifications are. Unless I missed it, I have not seen what yours are. For all I know you are just a passenger in the back.
An avionics engineer at Boeing on the 7J7 program that produced the B777
Also with United at SFO.
Which airline you work for? Malaysian airlines maybe? They don't set ELTs on during emergencies.
Yeah, well how about a link to a couple?
