(1) With not more than 25 assigned miscellaneous aircraft, 204.5 gross m2 [2,200
gross ft2].
(2) With not more than 50 assigned miscellaneous aircraft, 279 gross m2 [3,000
gross ft2].
(3) At an airfield supporting a division and up to 25 additional miscellaneous
aircraft, 492 gross m2 [5,300 gross ft2].
(4) At an airfield manned by approximately 60 personnel and which provides
interim facilities for Air Force air operations during airlifts, serves other Air Force
and Army aviation missions and houses a Medical Evacuation Team, 1,022 m2
[11,000 ft2] to 1,858 gross m2 [20,000 gross ft2].
14112 Aviation Unit Operations Building
A building, or space within a building, used by aviation units for administration and
training functions. It is similar to headquarters or administration and supply
buildings; however, normally it is located at an airfield.
Aviation units, with the exception of direct support maintenance units, require
support facilities for training and administration in addition to maintenance shops.
Such space will be provided in the hangar, or in a separate building near the hangar.
Normally, a separate unit operations building is not provided for miscellaneous
aircrafts. These administration space requirements should be provided in the hangar.
14115 Weather Station
A building which houses the Representative Weather Observation Station (RWOS),
Air Force Weather Service (AWS) operations at Army facilities, and nautical
weather services. RWOS is responsible for observing and disseminating current
weather conditions to users at an airfield or heliport. AWS service includes
observation, recording, reporting, forecasting, and advice to the Army on
meteorological conditions. Weather services are also provided for nautical and sea
traffic activities from these facilities. Weather stations are also frequently found at
RDT&E ranges and other related activities.
a. A Representative Weather Observation Station (RWOS) is necessary where an
Air Weather Service Detachment is assigned for making continued weather
observations critical to the landing and takeoff operations of aircraft. The station
should provide an unrestricted view of the runway and surrounding horizons.
b. The location and accommodations for the RWOS vary at each airfield depending
upon the results of a survey conducted by the Air Force Air Weather Service (AWS).
The approved site may be a jointly used control tower, rooms in the tower, a separate
building or rooms constructed on an existing building that provides sufficient space
for the functions and equipment. For control tower allowance, see category code
13310. As a separate building or as additional rooms, approximately 18.5 m2 [200
ft2] is required. This space allowance is in addition to the 139 m2 [1,500 ft2]
authorized the AWS in the airfield operations building for long range weather
forecasting.

Operational Facilities Other Than Building
Facilities other than buildings, such as towers or other structures, used in support of daily
activities on the facility, or for practicing tactical operations.
