CS ADR-DSN.B.080 Transverse slopes on runways

• ED Decision 2014/013/R found in: Aerodromes (139/2014) Part-ADR.AR Part-ADR.OR Part-ADR.OPS CS-ADR-DSN CS-HPT-DSN (Jun 2023)

CS ADR-DSN.B.080 Transverse slopes on runways ED Decision 2014/013/R (a) The safety objective of runway transverse slopes is to promote the most rapid drainage of water from the runway. (b) To promote the most rapid drainage of water, the runway surface should 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 should be: (1) not less than 1 % and not more than 1.5 % where the code letter is C, D, E or F; and; (2) not less than 1 % and not more than 2 % where the code letter is A or B; except at runway or taxiway intersections where flatter slopes may be necessary. (c) For a cambered surface, the transverse slope on each side of the centre line should be symmetrical. (d) The transverse slope should be substantially the same throughout the length of a runway except at an intersection with another runway or a taxiway where an even transition should be provided taking account of the need for adequate drainage.
