Is that what you would have done?
I honestly can't say FGD.
I have had completely different training in completely different times from that crew, flying different equipment.
What I can say is that if I am flying an aircraft without ANP alerting and GPS input to the FMS I confirm position prior to descending below MSA. Normally this is done using a VOR and a DME, sometimes by being radar identified, and rarely by overheading a station.Maybe I do that because of lessons learnt back then and if I was there I would have done the exact same thing as they did. Unless you were a Captain back then (I wasn't)I don't think you can say what you would have done.Times have changed.
