The following are movement areas in an aerodrome:
(a) Runway, (b) Taxi track or taxiway, (c) Apron, (d) Dispersal.
Runway: These are paved surfaces intended for take-off and landing run of aircraft. The number and orientation of runways at an airfield will depend upon the volume of traffic, runway occupancy time and climatological data on surface winds
Taxiway: These are paved surfaces provided for the taxiing of aircraft and intended to provide a link between one part of the aerodrome and another.
Apron: Means that part of an airport, other than the maneuvering area intended to accommodate the loading and unloading of passengers and cargo, the refueling, servicing, maintenance, and parking of aircraft, and any movement of aircraft, vehicles, and pedestrians necessary for such purposes.
Dispersal: an area adjacent to an airfield runway connected to the runway by taxi strips and used for parking airplanes in widely separated positions to protect them from enemy air attacks.
