Attachment 1
Aircraft Arresting Cable--That part of an aircraft arresting system which spans the runway surface or
flight deck landing area and is engaged by the aircraft arresting gear.
Aircraft Arresting Complex--An airfield layout comprised of one or more arresting systems.
Aircraft Arresting Gear--A device used to engage hook-equipped aircraft to absorb the forward
momentum of a routine or emergency landing or aborted takeoff.
Aircraft Arresting System--A series of components used to engage and absorb the forward momentum
of a routine or emergency landing or an aborted takeoff.
Aircraft Movement Area--For the purpose of this manual, the Aircraft Movement Area is defined as
that area of the airfield encompassed by the Primary Surface and the Clear Zones, as well as all apron
areas and taxiways, regardless of their location. See paragraph 3.15.1 for the specific use of this term.
Aircraft Wash Area--A specially designed paved area for washing and cleaning aircraft.
Aircraft Wash Rack--Paved areas provided at all facilities to clean aircraft in conjunction with
periodic maintenance.
Aircraft Rinse Facility--Paved areas provided at facilities to clean aircraft returning from flight and en
route to the parking area.
Airfield--An area prepared for the accommodation (including any buildings, installations, and
equipment), of landing and takeoff of aircraft.
Airfield Elevation--The established elevation, in terms of the nearest 300 mm (one foot) above mean
sea level, of the highest point of the usable landing area.
Airfield Reference Point--The designated geographical location of an airfield. It is given in terms of
the nearest hundredth of a second of latitude and longitude. The position of the reference point must be
as near to the geometric center of the landing area as possible, taking future development of the airfield
into account.
Airport--Refers to a civil or municipal airfield.
Airside Facilities--Facilities associated with the movement and parking of aircraft. These include
runways, taxiways, apron areas, associated navigational aids and imaginary surfaces.
Airspace--The space above ground or water areas which is or is not controlled, assigned, and/or
designated.
Alert Aircraft Parking--An exclusive paved area for armed aircraft to park and have immediate,
unimpeded access to a runway.
Alert Pad--Small paved areas provided for single alert aircraft parking.
Approach Control--A service established to control flights, operating under instrument flight rules
(IFR), arriving at, departing from, and operating in the vicinity of airports by direct communication
between approach control personnel and aircraft operating under their control.
Approach-Departure Clearance Surface--An inclined plane or combined inclined and horizontal
planes arranged symmetrically about the runway centerline extended. The first segment or the
beginning of the inclined plane is coincident with the ends and edges of the primary surface, and the
elevation of the centerline at the runway end. This surface flares outward and upward from these points.
