3.1.19 — Transverse slopes Besluit toezicht luchtvaart BES

Transverse slopes

To promote the most rapid drainage of water, the runway surface shall, f practicable, be cambered except where a single crossfall from high to low in the direction of the wind most frequently associated with rain would ensure rapid drainage. The transverse slope shall ideally be:

1.5 per cent where the code letter is C, D, E or F; and

2 per cent where the code letter is A or B;

but in any event shall not exceed 1.5 per cent or 2 per cent, as applicable, nor be less than 1 per cent except at runway or taxiway intersections where flatter slopes may be necessary.

For a cambered surface the transverse slope on each side of the center line shall be symmetrical.

Note. On wet runways with cross-wind conditions the problem of aquaplaning from poor drainage is apt to be accentuated. In Attachment A, Section 7 information is given concerning this problem and other relevant factors.

3.1.20 The transverse slope shall be substantially the same throughout the length of a runway except at an intersection with another runway or a taxiway where an even transition shall be provided taking account of the need for adequate drainage.

Note. Guidance on transverse slope is given in the Aerodrome Design Manual, Part 3.
