As our International Operations expand,
do you understand
Transition Level vs. Transition Altitude


Do you know the difference?

Do you include this in your briefing?

In the US it is the same for both, 18,000' & FL180.

In many other countries it is different, and quite low.

Port of Spain (TTPS) is a good example.

Transition Level is: FL55
Transition Altitude is : 4100'

So here's the question to ponder:

If you depart TTPS and you are cleared to 4100',
when do you set standard, prior to 4100', or after
climbing thru 4100' ?

Do you really understand QNH vs. QNE?

For extra credit:
What does the "Q" mean?
