slope on the corresponding parking position.

       (5) Subject to subsection (6), the grading of an apron must be such that it does not slope down towards the terminal building.

       (6) If a slope down towards a terminal building cannot physically be avoided, apron drainage must direct any spilled fuel away from the building and other structures adjoining the apron.

       (7) If a stormwater drain collects spilt fuel from the apron area, flame traps or interceptor pits must be provided to isolate the fuel and prevent it spreading from the apron area.

6.61 Apron bearing strength

        Each part of an apron must be capable of withstanding the traffic of the aircraft for which it is designed.

Note   This is to prevent the development of surface depressions or other hazards which may adversely affect aircraft operations.

6.62 Apron roads

        A marked vehicle roadway on an apron must not bring a vehicle closer than 3 m horizontally to any part of an aircraft on an aircraft parking position.

CHAPTER 6

Division 5 Blast and wash from aircraft propulsion systems

6.63 General

        Movement area design must protect the following from any damaging or injurious effects of jet blast, rotor wash and propeller wash:

(a) people;

(b) other aircraft;

(c) buildings;

(d) vehicles;

(e) equipment.

Note   People and property are not to be exposed to the dangers of high speed, high temperature airflows from blast and wash sources.

6.64 Jet blast, propeller wash and rotor wash air velocity

        For section 6.63, the maximum blast or wash velocity is as follows:

(a) 60 km/h:

 (i) for areas of an aerodrome traversed by flight crew, or passengers, boarding or leaving an aircraft; or

 (ii) for public areas, within or outside the aerodrome boundary, where passengers or members of the public are likely to walk or congregate;

(b) 80 km/h — for public areas where passengers or others are not likely to congregate;

(c) 50 km/h — for public roads where the vehicle speed is likely to be 80 km/h or more;

(d) 60 km/h — for public roads where the vehicle speed is likely to be less than 80 km/h;

(e) 80 km/h — for any personnel working near an aeroplane;

(f) 80 km/h — for equipment on an apron;

(g) 60 km/h — for light aeroplane parking areas with some risk of damage;

(h) 80 km/h — for light aeroplane parking areas with zero risk of damage;

(i) 100 km/h — for buildings and other structures.

Note   An aerodrome operator may use jet blast fences, appropriate building materials or other effective means to achieve the standards.
