CS ADR-DSN.D.295 Rapid exit taxiways

(a)The safety objective of rapid exit taxiway is to facilitate safe rapid exit of aeroplanes from a runway.

(b)A rapid exit taxiway should be designed with a radius of turn-off curve of at least:

(1)550 m where the code number is 3 or 4; and

(2)275 m where the code number is 1 or 2; to enable under wet conditions exit speeds of:

(i)93 km/h where the code number is 3 or 4; and

(ii)65 km/h where the code number is 1 or 2.

(c)The radius of the fillet on the inside of the curve at a rapid exit taxiway should be sufficient to provide a widened taxiway throat in order to facilitate early recognition of the entrance and turn-off onto the taxiway.

(d)A rapid exit taxiway should include a straight distance after the turn-off curve sufficient for an exiting aircraft to come to a full stop clear of any intersecting taxiway (Figure D-1).

(e)The intersection angle of a rapid exit taxiway with the runway should not be greater than 45°, nor less than 25° and preferably should be 30°. [Figure or form omitted from this preview — available in the Avioverse workspace library.] Figure D-1. Rapid exit taxiway
