Maybe I am misunderstanding NABR-2. It says:
"RUMO MAGNETICO (what is english word for that?):
000º A 179º - FL290, FL310, FL330, FL350, FL370, FL390, FL410
180º A 359º - FL300, FL320, FL340, FL360, FL380, FL400
Brasilia to Manaus is NW, aprox. 300º, i guess. So only even levels, correct?
Remember, S.José to Brasilia is not RSVM.
Sdruvss, that is correct. That the reason the
requested altitude of FL 360 was on the flight plan. Please remember that the altitude filed on a flight plan is only a
requested Flight Level. Just because a Flight Level is
requested does not mean that you will receive that Flight Level. Often crossing the North Atlantic I do not recieve the Flight Level I have requested.
ATC can assign
any Flight Level in its airspace
regardless of magnetic heading for various reasons.
This happens all over the world everyday.
I hope this helps you.
