CS ADR-DSN.D.305 Taxiway shoulders

(a)Straight portions of a taxiway where the code letter is C, D, E, or F should be provided with shoulders which extend symmetrically on each side of the taxiway so that the overall width of the taxiway and its shoulders on straight portions is not less than:

(1)44 m where the code letter is F;

(2)38 m where the code letter is E;

(3)34 m where the code letter is D; and

(4)25 m where the code letter is C.

(b)On taxiway curves and on junctions or intersections where increased pavement is provided, the shoulder width should be not less than that on the adjacent straight portions of the taxiway.

(c)When a taxiway is intended to be used by turbine-engined aeroplanes, the surface of the taxiway shoulder should be prepared so as to resist erosion and the ingestion of the surface material by aeroplane engines.
