For an aeroplane with a reference field length of 1 300 m, what maximum crosswind component should be assumed for landing or take-off?

24 km/h (13 kt), because the reference field length is 1 200 m or up to but not including 1 500 m.

For an aeroplane with a reference field length of 1 200 m, what maximum crosswind component should be assumed?

24 km/h (13 kt), because the reference field length is 1 200 m or up to but not including 1 500 m.

What is the assumed maximum crosswind component for an aeroplane with a reference field length of 1 100 m?

19 km/h (10 kt), because the reference field length is less than 1 200 m.

GM1 ADR-DSN.B.020 Choice of maximum permissible crosswind components

Q: What maximum crosswind component should be assumed for aeroplanes with a reference field length of 1 500 m or more, under normal circumstances?

37 km/h (20 kt), except that when poor runway braking action owing to an insufficient longitudinal coefficient of friction is experienced with some frequency, a crosswind component not exceeding 24 km/h (13 kt) should be assumed.

Q: Under what specific condition does the assumed maximum crosswind component for aeroplanes with a reference field length of 1 500 m or over drop to 24 km/h (13 kt)?

When poor runway braking action owing to an insufficient longitudinal coefficient of friction is experienced with some frequency.

Q: In applying GM1 ADR-DSN.B.015(a), what is the assumed crosswind limit for an aeroplane with a reference field length of exactly 1 500 m?

37 km/h (20 kt), unless poor runway braking action due to insufficient longitudinal coefficient of friction is frequent, in which case 24 km/h (13 kt) should be assumed.

Q: Does GM1 ADR-DSN.B.020 specify a different crosswind limit for aeroplanes with a reference field length of 1 500 m or over when runway braking is good?

No, the section only specifies a reduced limit (24 km/h) when poor runway braking action owing to an insufficient longitudinal coefficient of friction is experienced with some frequency; otherwise the limit is 37 km/h (20 kt).

GM1 ADR-DSN.B.020 Choice of maximum permissible crosswind components

ED Decision 2014/013/R

(a) In the application of GM1 ADR-DSN.B.015(a) it should be assumed that landing or take-off of aeroplanes is, in normal circumstances, precluded when the crosswind component exceeds:

(1) 37 km/h (20 kt) in the case of aeroplanes whose reference field length is 1 500 m or over, except that when poor runway braking action owing to an insufficient longitudinal coefficient of friction is experienced with some frequency, a crosswind component not exceeding 24 km/h (13 kt) should be assumed;

(2) 24 km/h (13 kt) in the case of aeroplanes whose reference field length is 1 200 m or up to but not including 1 500 m; and

(3) 19 km/h (10 kt) in the case of aeroplanes whose reference field length is less than 1 200 m.
