Chapter 2
2.9.3.4. Engine Repair and Engine Test Facilities. Engine repair and test facilities are provided
at air bases with aircraft engine removal, repair, and testing requirements. Siting of engine test
facilities should consider the impacts of jet blast, jet blast protection, and noise suppression.
2.9.3.5. Parts Storage. Covered storage of aircraft parts should be provided at all aviation
facilities and located close enough to the maintenance area to allow easy access to end-users.
2.9.4. Maintenance Aprons. These aprons should be sized according to the dimensions discussed in
Chapter 6.
2.9.5. Apron Lighting. Apron area lighting (floodlights) is provided where aircraft movement,
maintenance, and security are required at night, and during poor visibility. Type of lighting is based
on the amount of apron space or number of aircraft positions which receive active use during
nighttime operations.
2.9.6. Security. The hangar line typically represents the boundary of the airfield operations area.
Maintenance buildings should be closely collocated to discourage unauthorized access and enhance
facility security.
2.10. Aviation Operations Support Area:
2.10.1. Aviation Operations Support Facilities. Aviation operations support facilities include those
facilities that directly support the flying mission. Operations support includes air traffic control,
aircraft rescue and firefighting, fueling facilities, airfield operations center (airfield management
facility), squadron operations/aircraft maintenance units, and air mobility operations groups.
2.10.2. Location. Aviation operations support facilities should be located along the hangar line with
the central area typically being allocated to airfield operations (airfield management facility), air
traffic control, aircraft rescue and firefighting, and flight simulation. Aircraft maintenance facilities
should be located on one side of the runway to allow simplified access among maintenance areas,
aircraft, and support areas.
2.10.3. Orientation of Facilities. Facilities located either parallel or perpendicular to the runway
make the most efficient use of space. Diagonal and curved areas tend to chop up the area and result
in awkward or unusable spaces.
2.10.4. Multiple Supporting Facilities. When multiple aviation units are located at one facility, their
integrity may be retained by locating such units adjacent to each other.
2.10.5. Transient Facilities. Provisions should be made for transient and VIP aprons and buildings.
These facilities should be located near the supporting facilities discussed above.
2.10.6. Other Support Facilities. When required, other support facilities, such as aviation fuel
storage and dispensing, heating plants, water storage, consolidated parts storage, and motor pool
facilities should be sited on the far side of an access road paralleling the hangar line.
2.10.6.1. Air Traffic Control Facilities. The siting and height of the ATC tower cab is
determined by an operational assessment conducted by USAATCA and ATZQ-ATC-A (U.S.
Army Air Traffic Control Activity), and in accordance with MIL-HDBK 1024/1, Aviation
Operational and Support Facilities (Navy and Marine Corps). Air Force ATC towers are sited
in accordance with Attachment 18.
