CS ADR-DSN.B.065 Longitudinal slope changes on runways

(a)The safety objective of limiting the longitudinal runway slope changes is to avoid damage of aircraft and to enable safe use of runway by an aircraft.

(b)Where slope changes cannot be avoided, a slope change between two consecutive slopes should not exceed:

(1)1.5 % where the code number is 3 or 4; and

(2)2 % where the code number is 1 or 2.

(c)The transition from one slope to another should be accomplished by a curved surface with a rate of change not exceeding:

(1)0.1 % per 30 m (minimum radius of curvature of 30 000 m) where the code number is 4;

(2)0.2 % per 30 m (minimum radius of curvature of 15 000 m) where the code number is 3; and

(3)0.4 % per 30 m (minimum radius of curvature of 7 500 m) where the code number is 1 or 2.
