CS ADR-DSN.D.295 Rapid exit taxiways
ED Decision 2014/013/R
(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°.
