LEVEL
A GENERIC TERM RELATING TO THE VERTICAL POSITION OF AN AC IN FLIGHT MEANING VARIOUSLY HEIGHT ALTITUDE OR FL
HEIGHT
THE VERTICAL DISTANCE OF A LEVEL A POINT OR OBJECT CONSIDERED AS A POINT MEASURED FROM A SPECIFIC DATUM
ALTITUDE

FLIGHT LEVEL
A SURFACE OF CONSTANT ATMOSPHERIC PRESSURE WHICH IS RELATED TO A SPECIFIC PRESSURE DATUM 1013.25hPa AND IS SEPARATED FROM SUCH OTHER SURFACES BY SPECIFIC PRESSURE INTERVALS
TRANSITION ALTITUDE
IS THE ALTITUDE AT OR BELOW WHICH THE VERTICAL POSITION OF AN AC IS CONTROLLED BY REFERENCE TO ALTITUDE
TRANSITION LEVEL
THE LOWEST FLIGHT LEVEL AVAILABLE FOR USE ABOVE THE TA
TRANSITION LAYER
THE AIRSPACE BETWEEN THE TA AND THE TRL
AERODROME
