government may not be able to restrict public access to a draft report or any part thereof on behalf of
the State conducting the investigation. The standard for determining public access to information
requested from a U.S. government agency or a commercial business does not consider or require the
expressed consent of the State conducting an investigation.

ANNEX 14 − AERODROMES
VOLUME 1 − AERODROME DESIGN AND OPERATIONS
Chapter 1 General
1.2.1 Airports in the U.S. are for the most part owned and operated by local governments and
quasi−government organizations formed to operate transportation facilities. The Federal
Government provides air traffic control, operates and maintains NAVAIDs, provides financial
assistance for airport development, certificates major airports, and issues standards and guidance for
airport planning, design, and operational safety.
There is general conformance with the Standards and Recommended Practices of Annex 14,
Volume I. At airports with scheduled passenger service using aircraft having more than nine seats,
compliance with standards is enforced through regulation and certification. At other airports,
compliance is achieved through the agreements with individual airports under which Federal
development funds were granted; or, through voluntary actions.
1.3.1
1.3.2
1.3.3
1.3.4
In the U.S., the Airport Reference Code is a two−component indicator relating the standards used in
the airport’s design to a combination of dimensional and operating characteristics of the largest
aircraft expected to use the airport. The first element, Aircraft Approach Category, corresponds to
the ICAO PANS−OPS approach speed groupings. The second, Airplane Design Group, corresponds
to the wingspan groupings of code element 2 of the Annex 14, Aerodrome Reference Code. See

Chapter 2 Aerodrome Data
2.2.1 The airport reference point is recomputed when the ultimate planned development of the airport is
changed.
2.9.6
2.9.7
Minimum friction values have not been established to indicate that runways are ‘‘slippery when
wet.’’ However, U.S. guidance recommends that pavements be maintained to the same levels
indicated in the ICAO Airport Services Manual.
2.11.3 If inoperative fire fighting apparatus cannot be replaced immediately, a NOTAM must be issued. If
the apparatus is not restored to service within 48 hours, operations shall be limited to those
compatible with the lower index corresponding to operative apparatus.
2.12 e) Where the original VASI is still installed, the threshold crossing height is reported as the center of
the on−course signal, not the top of the red signal from the downwind bar.

Chapter 3 Physical Characteristics
3.1.2* The crosswind component is based on the ARC: 10.5 kt for AI and BI; 13 kt for AII and BII; 16 kt
for AIII, BIII and CI through DIII; 20 kts for AIV through DVI.
3.1.9* Runway widths (in meters) used in design are shown in the table below:
Width of Runway in Meters
Aircraft
Approach
Category
Airplane Design Group

A 181 231 −− −− 45 60
B 181 231 −− −− 45 60
C 30 30 302 45 45 60
D 30 30 302 45 45 60
1The width of a precision (lower than 3/4 statute mile approach visibility minimums) runway is 23 meters for a
runway which is to accommodate only small (less than 5,700 kg) airplanes and 30 meters for runways
accommodating larger airplanes.
2For airplanes with a maximum certificated take−off mass greater than 68,000 kg, the standard runway width is
45 meters.
3.1.12* Longitudinal runway slopes of up to 1.5 percent are permitted for aircraft approach categories C and
D except for the first and last quarter of the runway where the maximum slope is 0.8 percent.
3.1.18* Minimum and maximum transverse runway slopes are based on aircraft approach categories as
follows:
For categories A and B: 1.0 − 2.0 percent
