CS ADR-DSN.B.060 Longitudinal slopes of runways

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

(b)The slope computed by dividing the difference between the maximum and minimum elevation along the runway centre line by the runway length should not exceed:

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

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

(c)Along no portion of a runway should the longitudinal slope exceed:

(1)1.25 % where the code number is 4, except that for the first and last quarter of the length of the runway where the longitudinal slope should not exceed 0.8 %;

(2)1.5 % where the code number is 3, except that for the first and last quarter of the length of a precision approach runway Category II or III where the longitudinal slope should not exceed 0.8 %; and

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