What is QNH or QFE?
QNH is British for what Canadians call “altimeter setting”: the numbers to set in the little window on your altimeter to make the altimeter correctly show your height above sea level. QFE is the altimeter setting that makes the altimeter read ZERO at touchdown. The British military use QFE; perhaps because they can’t do addition well enough to calculate the circuit altitude without it. You can find more Q-codes at http://www.kloth.net/radio/qcodes.php.
