AFIS - Aerodrome Flight Information Service, providing information to, but not control of, aircraft using that aerodrome

CTR - Control Zone. An area of controlled airspace extending upwards from ground level to a specified upper limit.

TMA - Terminal Manoeuvring Area

Q-code - code system developed when air-to-ground communication was by wireless telegraphy, enabling many routine phrases and questions to be reduced to three letters. Now largely redundant, except these:

QDM magnetic bearing to a direction-finding station.
QDR magnetic bearing from the station.
QFE atmospheric pressure at aerodrome elevation. With its sub-scale set to the aerodrome QFE an altimeter will indicate height above that airfield.
QFU magnetic orientation of runway in use.
QNE reading in feet on an altimeter set to 1013.2 millibars (standard pressure) when the aircraft is at aerodrome elevation.
QNH altitude above mean sea level based on local station pressure.
QTE true line of position from a direction-finding station.
QUJ true bearing

VFR - Visual Flight Rules. Prescribed for the operation of aircraft in visual meteorological conditions (VMC). VMC is generally defined as five miles visibility or more and 1,000 feet vertical and one nautical mile horizontal clearance from cloud, but variations apply to aircraft operating below 3,000 feet amsl. Special VFR (SVFR) clearances are granted at the discretion of ATC for VFR flight through some controlled airspace where IFR usually apply. Also CVFR, Controlled VFR Flight.
