AIRPORT AND RUNWAY CLASSIFICATION
These classifications, along with the aircraft classifications defined previously, are used to determine
the appropriate FAA design standards to which the airfield facilities are to be designed and built.
Airport Reference Code (ARC): The ARC is an airport designation that signifies the airport’s highest
Runway Design Code (RDC), minus the third (visibility) component of the RDC. The ARC is used for
planning and design only and does not limit the aircraft that may be able to operate safely on the Air-
port. The current Airport Layout Plan (ALP) for the Airport, which will be updated as part of this plan-
ning effort, identifies an ARC of C-II for the Airport. The ultimate ARC on the ALP is called out as ARC
C/D-III.
Runway Design Code (RDC): A code signifying the design standards to which the runway is to be built.
The RDC is based upon planned development and has no operational component.
The AAC, ADG, and Runway Visual Range (RVR) are combined to form the RDC of a particular runway.
The RDC provides the information needed to determine certain design standards that apply. The first
component, depicted by a letter, is the AAC and relates to aircraft approach speed (operational charac-
teristics). The second component, depicted by a Roman numeral, is the ADG and relates to either the
aircraft wingspan or tail height (physical characteristics), whichever is most restrictive. The third com-
ponent relates to the visibility minimums expressed by RVR values in feet of 1,200 (⅛-mile), 1,600 (¼-
mile), 2,400 (½-mile), 4,000 (¾-mile), and 5,000 (1-mile). The RVR values approximate standard visibil-
ity minimums for instrument approaches to the runways. The third component should read “VIS” for
runways designed for visual approach use only.
Approach Reference Code (APRC): A code signifying the current operational capabilities of a runway
and associated parallel taxiway with regard to landing operations. Like the RDC, the APRC is composed
of the same three components: the AAC, ADG, and RVR. The APRC describes the current operational
capabilities of a runway under particular meteorological conditions where no special operating proce-
dures are necessary, as opposed to the RDC which is based upon planned development with no opera-
tional component. The APRC for a runway is established based upon the minimum runway-to-taxiway
centerline separation.
Departure Reference Code (DPRC): A code signifying the current operational capabilities of a runway
and associated parallel taxiway with regard to takeoff operations. The DPRC represents those aircraft
that can takeoff from a runway while any aircraft are present on adjacent taxiways, under particular
meteorological conditions with no special operating conditions. The DPRC is similar to the APRC, but is
composed of two components: ACC and ADG. A runway may have more than one DPRC depending on
the parallel taxiway separation distance.
