For a code number 4 runway, if the sum of absolute slope changes is 0.002, what is the required minimum distance?

The product is 0.002 × 30 000 m = 60 m, which is greater than 45 m, so the minimum distance is 60 m.

What is the minimum distance between slope changes for a code number 3 runway if the sum of absolute slope changes is 0.01?

The distance should be at least 150 m (0.01 × 15 000 m = 150 m), which is greater than 45 m, so 150 m.

When must the distance between slope changes be at least 45 m?

The distance must be at least 45 m when the product of the sum of absolute slope changes and the applicable multiplier (30 000 m, 15 000 m, or 5 000 m) is less than 45 m; the greater of the two values applies.

CS ADR-DSN.B.075 Distance between slope changes on runways

Q: What is the minimum distance required between the points of intersection of two successive slope changes on a runway for code number 4?

The distance should not be less than the sum of the absolute numerical values of the corresponding slope changes multiplied by 30 000 m, or 45 m, whichever is greater.

Q: For a runway with code number 2, how is the minimum distance between successive slope changes calculated?

The distance should not be less than the sum of the absolute numerical values of the corresponding slope changes multiplied by 5 000 m, or 45 m, whichever is greater.

CS ADR-DSN.B.075 Distance between slope changes on runways

ED Decision 2014/013/R

Undulations or appreciable changes in slopes located close together along a runway should be avoided. The distance between the points of intersection of two successive curves should not be less than:

(a) the sum of the absolute numerical values of the corresponding slope changes multiplied by the appropriate value as follows:

(1) 30 000 m where the code number is 4;

(2) 15 000 m where the code number is 3; and

(3) 5 000 m where the code number is 1 or 2; or

(b) 45 m;

whichever is greater.
