f. Exceptions. At facilities other than assault landing zones where a parallel taxiway is not
provided, the runway shall be designed as Type A Traffic Area with double the required traffic.
4. ARMY AIRCRAFT DESIGN LOADS AND PASS LEVELS. Army airfield pavements will be
designed according to mission requirements of each airfield, heliport, and helipad for a 20-year design
life to include the military and civilian peacetime aircraft traffic plus all anticipated special operations
and/or mobilization requirements defined by the Army installation and its MACOM. The total 20-year
design aircraft traffic is based on specific aircraft types, their mission operational weights, and their
projected pass levels. The airfield mission traffic used for design requires the approval of the MACOM
and USAASA. Aircraft hangar floors or apron pavements shall not be designed for jacking loads as long
as the foot print of the jack is equal to or greater than the contact area of the combined tires on the
aircraft gear being elevated. Army aircraft operational pavements may consist of one or a combination
of the following Army airfield-heliport classes:
a. Class I. Heliports and helipads with aircraft maximum operational weights equal to or less than
11,340 kilograms (25,000 pounds). The design of heliports and helipads will be based on the number of
equivalent passes of the UH-60 aircraft at a 7,395-kilogram (16,300-pound) operational weight. The
projected equivalent passes will be generated for the airfield mission traffic but shall not be less than
50,000 passes for a heliport nor less than 20,000 passes for a helipad.
b. Class II. Heliports that support aircraft with maximum operational weights over 11,340 kilograms
(25,000 pounds). The design will be based on the number of equivalent passes of the CH-47 aircraft at
a 22,680-kilogram (50,000-pound) operational weight. The projected equivalent passes will be
generated for the airfield mission traffic but shall not be less than:
(1) 50,000 passes for visual flight rules (VFR) heliports.
(2) 20,000 passes for VFR helipads.
(3) 100,000 passes for instrument flight rules (IFR) heliports.
(4) 30,000 passes for IFR helipads.
c. Class III. Airfields that primarily support fixed wing aircraft requiring a Class A runway as defined
in UFC 3-260-01. The design will be based on the projected number of aircraft operations but not less
than 50,000 passes of a C-23 aircraft at an 11,200-kilogram (24,600-pound) operational weight plus
10,000 passes of a CH-47 aircraft at an operational weight of 22,680-kilograms (50,000-pounds).
d. Class IV. Airfields supporting aircraft requiring a Class B runway as defined in EI 02C013/
AFMAN 32-1013/NAVFAC P-971.
(1) The design for an airfield with its longest runway extending less than or equal to
1,525 meters (5,000 feet) will be based on the number of projected equivalent passes of the C-130
aircraft at a 70,310-kilogram (155,000-pound) or the C-17 aircraft at 263,100-kilograms (580,000-pound)
operational weight. The projected equivalent passes will be generated for the airfield mission traffic but
shall not be less than 75,000 passes for the C-130 or 50,000 passes for the C-17.
(2) The design for an airfield with its longest runway extending over 1,525 meters (5,000 feet)
but less than or equal to 2,745 meters (9,000 feet) will be based on the number of projected equivalent
