CS ADR-DSN.B.180 Longitudinal slopes on runway strips

(a)The safety objective of longitudinal runway strip slope is to define maximum gradient values that should not interfere with the safe use of the runway strip by an aircraft.

(b)A longitudinal slope along that portion of a strip to be graded should not exceed:

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

(2)1.75 % where the code number is 3; and

(3)2 % where the code number is 1 or 2.

(c)Longitudinal slope changes on that portion of a strip to be graded should be as gradual as practicable, and abrupt changes or sudden reversals of slopes should be avoided.
