Does anyone know the reason of this message? It's coming up on every flight i make! Even if I'm always correcting the altimeter (with the B key) and maintaining my flight level, there's always a moment of my flight where i got this horrendous message "American Pacific 1123 IFR flight plan cancelled". I always check my correct altitude using the information on SHIFT+Z, and even though my altitude is absolutely correct, ATC cancels my flight plan. First it sends about 3 messages saying I'm 300 feet below my assigned altitude and asks me to expedite my climb to my assigned flight level, then it cancels it.Is there any way to correct it, or avoid it?Cheers!

When crossing 16000 ft set your altimeter to standard (29.92) and do not, I repeat do not adjust your altimeter.:-)Alex

Just that???I was trying to follow the altimeter settings ATC gave me... liers!!! lolThanks a lot

Actually once you pass I believe 18000' they will no longer tell you the current altimeter.

No wonder why when i leave Salzburg to Paris, I arrive in Charles de Gaule still withthe Frankfurt altimeter.

Correct. Once you pass 18,000 the altimeter should be set to 29.92. From that point on, when you are asked to contact a center, and the altimeter is set to 29.92, no altimeter reading will be given.http://ftp.avsim.com/dcforum/DCForumID8/10068.html

If you have FSUIPC you can assign a key to set altimeter to 29.92.I use the Delete key to set altimeter above 18,888 feet and the B key below 18,000 feet.

BINGO! Never rely on SHIFT-Z Alt. reading when above 18k.. Use the reading on your instruments, as you adjust yourself to 29.92 from the "real" pressure the difference in those two numbers will increase..So check your Altitude on your Mini or Normal Panel for correct Alt. readout..
