IR Implementing rule

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

(a) The safety objective of limiting the longitudinal [runway](https://avioverse.aero/glossary/easa/runway) slope is to enable stabilized and safe use of runway by an [aircraft](https://avioverse.aero/glossary/easa/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.
