Flight level: Standards, Metre flight levels & Transition altitude

In aviation, a flight level (FL) is an aircraft's altitude as determined by a pressure altimeter using the International Standard Atmosphere. A flight level is a surface of constant atmospheric pressure used to define an aircraft’s vertical position relative to other aircraft when flying above the transition altitude. It is expressed in hundreds of feet…
