(intermediate power)). Typical parking arrangements and associated clearances are provided in
184.108.40.206. Departure Sequencing. Formal aircraft egress patterns from aircraft parking positions to
the apron exit taxiways should be established to prevent congestion at the apron exits. For
example, aircraft departing from one row of parking positions should taxi to one exit taxiway,
allowing other rows to simultaneously taxi to a different exit.
220.127.116.11. Army and Navy Aprons. Army aircraft parking aprons are divided into three categories:
unit, general purpose, and special purpose. The category to be provided is based on the mission
support requirement of the facility.
18.104.22.168.1. Unit Parking Apron. The unit parking category supports fixed- and rotary-wing
aircraft assigned to the facility.
22.214.171.124.2. General Purpose Apron. When no tenant units are assigned to an aviation facility,
and transient aircraft parking is anticipated, a personnel loading apron or aircraft general
purpose apron should be provided in lieu of a mass parking apron.
126.96.36.199.3. Special Purpose Apron. Special purpose aprons are provided for specific
operations such as providing safe areas for arming/disarming aircraft and other specific
mission requirements that demand separation of or distinct handling procedures for aircraft.
188.8.131.52. Apron/Other Pavement Types. Special use aprons may exist on an aviation facility.
Further information on these aprons/pavements may be found in Chapter 6.
2.9. Aircraft Maintenance Area (Other than Pavements). An aircraft maintenance area is required
when aircraft maintenance must be performed regularly at an aviation facility. Space requirements for
maintenance facilities are based on aircraft type.
2.9.1. Aircraft Maintenance Facilities. The aircraft maintenance facility includes, but is not limited
to: aircraft maintenance hangars, special purpose hangars, hangar access aprons, weapons system
support shops, aircraft system testing and repair shops, aircraft parts storage, corrosion control
facilities, and special purpose maintenance pads. The aircraft maintenance area includes utilities,
roadways, fencing, and security facilities and lighting.
2.9.2. Aviation Maintenance Buildings (Air Force and Navy). For aviation maintenance building
information for the Air Force, see AFH 32-1084; for the Navy, see MIL HDBK 1028/1, Aircraft
2.9.3. Aviation Maintenance Buildings (Army):
184.108.40.206. Maintenance Hangars. Maintenance hangars are required to support those aircraft
maintenance, repair, and inspection activities which can be more effectively accomplished while
the aircraft is under complete cover. The size requirement for maintenance hangars is
determined by the number of aircraft assigned.
220.127.116.11. Security and Storage Hangars. These hangars are limited in use and do not require the
features normally found in maintenance hangars.
18.104.22.168. Avionics Maintenance Shop. Avionics maintenance space should normally be provided
within the maintenance hangar. However, a separate building for consolidated avionics repair
may be provided at aviation facilities with multiple units.
