Difference between TA and TL?
What’s the difference between TA (Transition Altitude) and TL (Transition Level)? Thanks in advance!

In the US TA is 18,000ft, in Europe sometimes as low as 3,000ft. Transition level (TL) is the flight level (FL) at which, when descending, you reset your altimiter to QNH, or the local altimeter setting. –> Last edited by RatRace; 02-03-2009 at 10:12 AM.
