I have confusion regarding with blw topic and I would just get your comments. Here my question what JAr Ops mean with critical engine power(s) ? Two possibility, one engine failure (for twin engine) and two engine failure (4 engines a/c).. or all engines fail? Even if it is all engine failure, a/c will glide closest suitable a/p why other all other a/c's limitation : 100 nautical miles, whichever is the lesser...
Thanks for your comments from now..
