at about 20 seconds into recording: "Good evening Director, AirForce One passing
7,200 for 6,000 feet".
The Transition altitude for Stanstead is 6,000 so anything higher is a Flight Level on the standard pressure. He was given a descent to altitude 6,000 feet, so presumably the altimeter would have been changed to the local pressure at some point in the descent.
Guess it's correct to report in as above, instead of, "passing
FL72 for altitude 6,000 feet". Anyone know which is more correct?
It appears that the transition level when the local pressure is 1022millibars is FL60 so FL70 would have been an available/useable flight level.
http://en.wikipedia.org/wiki/Flight_levelor the questions as a US equivalent "Descending through FL192 for 17,000 feet" or "Descending through 19,200 for 17,000 feet"?
