AIRCRAFT HANGAR PAVEMENTS
8.1. General Requirements. Hangars provide space for various aircraft activities: scheduled inspections;
landing gear tests; weighing of aircraft; major work and maintenance of fuel systems and airframes; and
technical order compliance and modifications. These activities can be more effectively accomplished
while the aircraft is under complete cover. Pavement for hangar floors must be designed to support aircraft
loads. Hangars provide covered floor space to accommodate aircraft. Clearance must be provided
between the aircraft and the door opening, walls, and ceiling of the hangar. This chapter does not apply to
the Navy and Marine Corps other than to provide applicable Navy publications where additional
information may be found.
8.2. Aircraft Modules Space. Table 8.1 presents the dimensions and sizes of modules for various Army
aircraft. These modules are used to determine hangar size.
Table 8.1. Aircraft Space Module for Army Aviation Facilities.*
Type of Aircraft**
UH-1, AH-1, OH-58 (2 Blades)
UH-1 (4 Blades)
UH-60 (4 Blades)
AH-64 (4 Blades)
OH-58 (4 Blades)
CH-47 (6 Blades Tandem)
C-12 Fixed Wing
* Aircraft space modules shown in the table are derived by adding approximately 6 meters [20 feet] to the
aircraft width and length dimensions, thus providing a 3-meter [10-foot] wide buffer/work space around
** Equate aircraft such as U-6, U-8, and U-21 to C-12; equate C-23 to C-12; equate AH-1S to UH-1 (4
NOTE: Metric units apply to new airfield construction, and where practical, modifications to existing
airfields and heliports, as discussed in paragraph 1.4.4.
8.3. Hangar and Shelter Clearances. The interior design of covered shelters must include the clearances
between aircraft and door openings, walls, and ceilings, and also parking clearances between other aircraft.
These clearances are essential to ensure aircraft are protected from structural damage. The clearances
allow personnel to maneuver more easily during aircraft maintenance. Hangar and alert/hardened shelter
clearance information is presented in Table 8.2.
