president:
Just to be clear. I know how to deal with energy, approach and landing. I am not looking for piloting advise. I am asking whether something is legal or not. Anybody with a legal reference ?
As GF stated, it caused a CFIT for TWA 514 in 1974. Caused a regulatory change in the U.S. to maintain last assigned altitude until on a published route or segment of an approach. Also, in the U.S. MSAs are for emergency use only.
I've been in this business for a long time and this is the first time I've heard the term "platform altitude." That's not termed used in the U.S. Perhaps it is elsewhere. Do you know if there is an ICAO definition?
