3.3.1 Where the end of a runway is not served by a taxiway or a taxiway turnaround and where the code letter is

D, E or F, a runway turn pad shall be provided to facilitate a 180-degree turn of airplanes. (See Figure 3-1.)

3.3.2 Where the end of a runway is not served by a taxiway or a taxiway turnaround and where the code letter is A, B or C, a runway turn pad shall be provided to facilitate a 180-degree turn of airplanes.

Note 1. Such areas may also be useful f provided along a runway to reduce taxiing time and distance for airplanes which may not require the full length of the runway.

Note 2. Guidance on the design of the runway turn pads is available in the Aerodrome Design Manual, Part I. Guidance on taxiway turnaround as an alternate facility is available in the Aerodrome Design Manual, Part 2.

3.3.3 The runway turn pad may 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.

Note The initiation of the turn would be facilitated by locating the turn pad on the left side of the runway, since the left seat is the normal position of the pilot-in-command.

3.3.4 The intersection angle of the runway turn pad with the runway shall not exceed 30 degrees.

3.3.5 Recommendation. The nose wheel steering angle to be used in the design of the runway turn pad shall not exceed 45 degrees.

3.3.6 The design of a runway turn pad shall be such that, when the cockpit of the airplane for which the turn pad is intended remains over the turn pad marking, the clearance distance between any wheel of the airplane landing gear and the edge of the turn pad shall be not less than that given by the following tabulation:

Code letter | Clearance

A | 1.5m

B | 2.25m

C | 3 m if the turn pad is intended to be used by airplanes with a wheel base less than 18 m;

4.5 m if the turn pad is intended to be used by airplanes with a wheel base equal to or greater than 18 m.

D | 4.5m

E | 4.5m

F | 4.5m

Note. Wheel base means the distance from the nose gear to the geometric center of the main gear.

3.3.7 Where severe weather conditions and resultant lowering of surface friction characteristics prevail, a larger wheel-to-edge clearance of 6 m shall be provided where the code letter is E or F.
