Chapter 2
2.3.3. Requirements. Each functional proponent is responsible for providing the appropriate
operational information to be used in the planning of an aviation facility. In addition, planning
should be coordinated with all users (operations, air traffic control, safety) of the aviation facility,
including the FAA, to determine immediate and long range uses of the aviation facility.
2.3.3.1. Operational Information. Functional proponents will provide, at a minimum, existing
and projected operational information needed for planning aviation facilities:
2.3.3.1.1. Mission statements.
2.3.3.1.2. Aircraft operational counts, traffic levels, and traffic density.
2.3.3.1.3. Type, size, and number of units/organizations and personnel.
2.3.3.1.4. Type, size, and number of equipment (aircraft, weapons systems, vehicles, etc.).
2.3.3.1.5. Once the above items are established, land requirements to support the aircraft
mission can be established.
2.3.3.2. Engineering Information. Engineering information provided will include, as a
minimum: graphical maps and plans, facility condition assessments, and tabulation of existing
facilities.
2.3.4. Safety. The planning and design of an aviation facility will emphasize safety for aircraft
operations. This includes unobstructed airspace and safe and efficient ground movements. Protect
air space by promoting conscientious land use planning, such as compatible zoning and land
easement acquisition.
2.3.5. Design Aircraft. Aviation facilities typically are designed for a specific aircraft known as the
"critical" or "design" aircraft, which is the most operationally and/or physically demanding aircraft
to make substantial use of the facility. The critical or design aircraft is used to establish the
dimensional requirements for safety parameters such as approach protection zones, lateral clearance
for runways, taxiways and parking positions, and obstacle clearance. In many cases, the "geometric"
design aircraft may not be the same aircraft as the "pavement" design aircraft.
2.3.6. Airspace and Land Area. Aviation facilities need substantial air space and land area for safe
and efficient operations and to accommodate future growth or changes in mission support.
2.3.6.1. Ownership of Clear Zones and Accident Potential Zones. When planning a new
aviation facility or expanding an existing one, clear zones should be either owned or protected
under a long term lease, and Accident Potential Zones (APZ) should be zoned in accordance
with DoD Instruction 4165.57, Air Installation Compatible Use Zone (AICUZ). Ownership of
the APZ is desirable but not required.
2.3.6.2. Land Use Within the Clear Zone and Accident Potential Zones. Requirements for land
use below approach-departure surfaces are provided in DoD Instruction 4165.57 and are
summarized in Attachment 4.
2.3.6.3. Explosives. Where explosives or hazardous materials are handled at or near aircraft,
safety and separation clearances are required. The clearances are based on quantity-distance
criteria as discussed in Attachment 10.
2.3.6.4. Landside Safety Clearances. Horizontal and vertical operational safety clearances must
be applied to landside facilities and will dictate the general arrangement and sizing of facilities
and their relationship to airside facilities. Landside facilities will vary in accordance with the
