A or B taxiway — 1.0% per 25 m (minimum radius of curvature of 2 500 m).

       (3) The longitudinal slope values expressed in subsections (1) and (2) do not apply at the intersection of a taxiway with a runway or other taxiway if:

(a) there are conflicting drainage requirements or slope requirements; and

(b) alternative taxiway longitudinal slope values are as follows:

 (i) arrived at after a safety analysis using the safety management system and the risk management plan;

 (ii) as close as practicable to values expressed in subsections (1) and (2);

 (iii) demonstrably safe for aircraft operations;

 (iv) recorded in the aerodrome manual.

6.41 Taxiway transverse slope

       (1) The transverse slope on any part of a taxiway must not permit any pooling or ponding of water on the taxiway.

       (2) For design purposes, a transverse slope on a taxiway must be within the range of the percentage figures in column 1 in Table 6.41 (2) but a construction tolerance above or below the range is allowed within the limits specified in column 2.

     Table 6.41 (2)   Taxiway transverse slope values
Design slope  Construction tolerance
1.0% - 2.0%   ± 0.5%

       (3) The taxiway transverse slope values expressed in Table 6.41 (2) do not apply at the intersection of a taxiway with a runway or another taxiway if:

(a) there are conflicting drainage requirements or slope requirements; and

(b) alternative taxiway transverse slope values are as follows:

 (i) arrived at after a safety analysis using the safety management system and the risk management plan;

 (ii) as close as practicable to values expressed in Table 6.41 (2);

 (iii) demonstrably safe for aircraft operations;

 (iv) recorded in the aerodrome manual.

6.42 Taxiway sight distance

       (1) The unobstructed line of sight along the surface of a taxiway, from a point above the taxiway, must not be less than the distance determined using Table 6.42 (1).

       (2) In Table 6.42 (1), for a taxiway with a code letter mentioned in a row of column 1, the minimum unobstructed line of sight along the surface of the taxiway must not be less than the distance mentioned in the same row of column 2.

     Table 6.42 (1)   Taxiway line of sight
Taxiway code letter  Minimum line of sight
A                    150 m — from a point 1.5 m above taxiway
B                    200 m — from a point 2 m above taxiway
C, D, E or F         300 m — from a point 3 m above taxiway

6.43 Taxiway bearing strength

        The bearing strength of a taxiway must be:

(a) at least equal to the bearing strength of the runway it serves; or

(b) otherwise capable of bearing the weights and movement frequencies of the types of aeroplanes
