Any1 know what the initials stand for? For example what Q stands for, what N stands for, H stands for?
Just out of curiousity!
Thanks

The letters don't stand for anything in particular but are aligned with a code used in the days of Morse for brevity. I have used the term QSY (for frequnecy change) in the 70's.

See the following for all the details.

I like to think of E as "en route," H as "height (above SL)" and F for "Field Elevation." But I don't think that's official.

My money's on some sort of French acronym.

Don't forget about Transition Altitude and Transition Level if your are trying to learn about overseas ops!

Like Andy mentioned, Q codes are not acronyms, the letters don't stand for anything.

The "Q" is a throwback to morse code days and used for brevity. It was short for Question. For example, Question of what your altimeter seting is: QNH, QFE. See the link on Andy Neil's post above.

All the above posted answers are valid. You will not hear "Q" terminolgy very much in the United States. Even FAA ATC contollers are unfamiliar with the terms.

Most ICAO participating countries use the terms, especially Europe, Africa, and Mexico.

Other terms frequently used are FIR, CZ, UTA, and TMA boundries and are frequently used in non-radar environments in ICAO operations.
