Phraseology + altimeters
That's good to know. Is RIS also terminated when A/c go low level? Surely these a/c would have decended out of radar cover. So I couldn't figure why the RIS wasn't terminated.
Something else that puzzles me.
In the original thread about the CM there was information about the pressure setting for the area and it seemed that if the a/c were on regional and at 4,000ft indicated, they would not have hit the mountain due to the difference between the regional and the actual.
Many words have been written about the theory that these a/c had descended below 4,000ft. So...........was there no readable/useable information recovered from the wreckage to confirm what was on the altimeters? Was it too badly damaged?
