APRONS AND OTHER PAVEMENTS
6.1. Contents. This chapter presents design standards for fixed and rotary-wing aircraft parking
aprons, access aprons, maintenance pads, and wash racks. It provides minimum wing-tip clearance
requirements, grades, and lateral clearance standards, as well as typical aircraft parking arrangements.
The general principals of this chapter apply to the US Navy and Marine Corps. Specific data for Navy
and Marine Corps aprons is contained in the referenced publications. See Figures 6.39 and 6.40, and
Tables 6.6 through 6.9 for Navy/Marine Corps aircraft parking apron criteria (taken from NAVFAC P-
6.2. Apron Requirements. Aprons must provide sufficient space for parking fixed- and rotary-wing
aircraft. They should be sized to allow safe movement of aircraft under their own power. Consider the
effects of jet blast turbulence and temperature during design. Programming requirements for Air Force
aviation facilities are found in AFH 32-1084, Standard Facility Requirements Handbook. Requirements
for Navy and Marine Corps aviation facilities are contained in NAVFAC P-80 and MIL-HDBK-1021/1,
General Concepts for Airfield Pavement Design. The general principles of this chapter apply to the Navy
and the Marine Corps. Specific data on Navy/Marine Corps aprons is contained in the referenced

6.4. Aircraft Characteristics. Dimensional characteristics of various military, civil, and commercial
fixed- and rotary-wing aircraft are available in U.S. Army Engineering Technical Letter 1110-3-394,
Aircraft Characteristics for Airfield-Heliport Design and Evaluation,
6.5. Parking Apron for Fixed-Wing Aircraft. Fixed-wing parking at an aviation facility may consist
of separate aprons for parking operational aircraft, transient aircraft and transport aircraft, or an apron
for consolidated parking.
