What is a CTR? (A Control Zone)
an area around some aerodromes where ATC is provided to all flights.
It extends from ground level to a specified level with a minimum lateral dimension of 5nm.
What is a Terminal control area?
Where controlled airspace meet in the vicinity of one or more major aerodromes (class A-E above 6000ft amsl, class E below)
What is a Control Area? CTA
Airspace where ATC is provided and which extends from a base altitude to an upper Flight Level.
What is an airway?
A control area in the form of a corridor with an identification code, deliniated by radio navigation aids.
It extends 5nm each side of a straight line joining certain places, with vertical limits.
