I’ve been looking st that topo map posted earlier in this thread just trying to figure out why the pilot turned left into higher terrain and the only thing I can think of is for the previous part of the flight a turn left or right would have likely made little difference up until he started to parallel the mountains. I know it’s been mentioned that the highway diverts there and he was probably trying to find that ground reference through the clouds but when the crap hit the fan and he presumably lost reference to the ground it looks like he lost positional awareness too or forgot he had made a turn to parallel the mountains( although it’s been mentioned he circled for a while so I could see how it could be easy to just lose where you are in the world even with a ton of tools at your disposal.)
Besides wondering what the climb rate is for a helicopter like that, my flat lander pilot ignorance on display has led me to another question— whenever a plane descends below a safe altitude for their radar position, by me, the ATC calls out something like “low altitude alert, check altimeter setting immediately.” Is that not true/possible/even a procedure for mountaneous terrain? I have not listened to the ATC recordings here but just wondering if ATC could have given more notice here?
