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:

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 C and D: 1.0 . 1.5 percent
3.2.2 The U.S. does not require that the minimum combined runway and shoulder widths equal 60 meters. The widths of shoulders are determined independently.
3.2.3* The transverse slope on the innermost portion of the shoulder can be as high as 5 percent.
3.3.3 3.3.4* 3.3.5* A strip width of 120 meters is used for code 3 and 4 runways for precision, nonprecision, and non.instrumented operations. For code 1 and 2 precision runways, the width is 120 meters. For non.precision/visual runways, widths vary from 37.5 meters up to 120 meters.
3.3.9* Airports used exclusively by small aircraft (U.S. Airplane Design Group I) may be graded to distances as little as 18 meters from the runway centerline.
3.3.14* The maximum transverse slope of the graded portion of the strip can be 3 percent for aircraft approach categories C and D and 5 percent for aircraft approach categories A and B.
3.3.15* The U.S. does not have standards for the maximum transverse grade on portions of the runway strip falling beyond the area that is normally graded.
3.3.17* Runways designed for use by smaller aircraft under non.instrument conditions may be graded to distances as little as 18 meters from the runway centerline (U.S. Airplane Design Groups I and II).
3.4.2* For certain code 1 runways, the runway end safety areas may be only 72 meters.
