Instrument cross check
I do not withdraw my explanation of the cross check requirements but having seen the second unabridged video,
I soften my critical remarks about the PF. He did do a DME alt x check( edited out in 1st video)
However, the aim of the exercise is to learn something that just might save your arse one nite when tired, pissed off, or just in a plain old bad humour.
I do not and have not set my self up as a critical whiz boy, I was a poor instrument pilot who suffered from the leans even after 30 years Instrument flying in Heavy and little jets.
I had a similar experience back in 1965 at NFFN, where a cross check that was ratified at 2400ft established that the machine was on a false glideslope.
The initial response was to revert to a twin NDB( for you new smart arsed pilots that was the only system for several decades and is still a valid sytem where it exists)
I am still in the loop, I am a curent and practising Flight Instructor, with a rating that has been valid and active since 1961.
I will add I am still learning, are you?
