CS ADR-DSN.B.095Runway turn pads
(a)The safety objective of the runway turn pad is to facilitate a safe 180-degree turn by aeroplanes on runway ends that are not served by a taxiway or taxiway turnaround.
(b)Where the end of a runway is not served by a taxiway or a taxiway turnaround, and if required, a runway turn pad should be provided to facilitate a 180-degree turn of aeroplanes.
(c)The design of a runway turn pad should be such that when the cockpit of the most demanding aircraft for which the turn pad is intended remains over the turn pad marking, the clearance distance between any wheel of the aeroplane landing gear and the edge of the turn pad should be not less than that given by the following tabulation:
| Clearance | Outer Main Gear Wheel Span (OMGWS) | |||
|---|---|---|---|---|
| Up to but not including 4.5 m | 4.5 m up to but not including 6 m | 6 m up to but not including 9 m | 9 m up to but not including 15 m | |
| 1.50 m | 2.25 m | 3 ma or 4 mb | 4 m | |
| a if the turn pad is intended to be used by aeroplanes with a wheel base less than 18 m. b if the turn pad is intended to be used by aeroplanes with a wheel base equal to or greater than 18 m. | ||||
| Note: Wheel base means the distance from the nose gear to the geometric centre of the main gear. | ||||
(d)The runway turn pad should be located on either the left or right side of the runway and adjoining the runway pavement at both ends of the runway and at some intermediate locations where deemed necessary.
(e)The intersection angle of the runway turn pad with the runway should not exceed 30 degrees.
(f)The nose wheel steering angle to be used in the design of the runway turn pad should not exceed 45 degrees.
