Aircraft Special Purpose Apron
Special purpose aprons may be authorized for providing safe areas for arming and/or
disarming aircraft weapons; loading and unloading ammunition; special handling
and/or decontamination facilities for CBR warfare items; and for special security
areas. Special-purpose aprons required to conduct defueling operations will be
provided at Army aviation facilities. Design will be predicated on the largest aircraft
and adequate space for fire support equipment and defueling vehicle and apparatus.
Grounding points will be provided. The scope of the apron area and the type of
supporting facilities for these special-purpose aprons will be individually justified on
the basis of the mission requirements. Safety clearances, appropriate to the
requirements of the apron, will be observed. Airfield maps and plans will identify the
purpose of the apron and show the required safety clearance distances. Explosives
clearances are discussed in Appendix I of this Manual.
11383
Aircraft Loading Aprons, Unsurfaced
An unpaved, prepared surface for loading cargo aircraft; loading personnel for
medical evacuation and transient aircraft operations. An aircraft loading apron
provides and area for arming and disarming aircraft weapons, loading and unloading
ammunition, special handling or decontamination of chemical, biological radiological
(CBR) warfare items, and for special security operations.

Aircraft Compass Calibration Pads
A prepared surface for calibration of air navigation equipment. A rigid paved pad in
a magnetically quiet zone of the airfield. The pad surface is painted with alignment
markings which are used in the precise calibration of air navigation equipment. The
facility may include a taxiway which connects the pad to the main taxiway or apron.
One compass calibration pad may be provided at Army airfields or heliports where
fifteen or more aircraft are permanently assigned, and at Army depots where aircraft
maintenance missions are assigned (AR 750-1, Army Material Maintenance Policies
which should be located in an electronically quiet zone of the airfield. Compass
calibration pads are typically circular and are sized to accommodate one of the
assigned or mission aircraft. Compass calibration pads are further discussed in
Chapter 6 of this manual.
