8.49 Aircraft type designator markings

       (1) An aircraft type designator marking may be used to designate which aircraft types may be accommodated in the area to which the marking applies.

       (2) Where an aircraft type designator marking is provided, the designation must use only the list of aircraft type designators published in ICAO Doc 8643, Aircraft Type Designators.

Note 1   For ICAO documents, see section 1.07.

Note 2   IATA designations, or common use terms such as "All aircraft", are not permitted.

       (3) If:

(a) a stop line or parking position is to accommodate a number of aircraft types; and

(b) there is insufficient space to designate all of the aircraft types;

        then:

(c) the aircraft type designation marking must:

           (i) list the largest or most critical aircraft types — provided all smaller or less critical aircraft may safely use the stop line, or the entire parking position (as applicable); or

           (ii) list the range of aircraft types that may use the stop line or parking position — provided all aircraft types within the range may safely use the line or position; or

(d) an alternate system of control must be documented in the aerodrome manual and implemented to prevent unsuitable aircraft types from using the stop line or parking position.

8.50 Parking clearance line

       (1) A parking clearance line delineates the area within which the whole of an aircraft is to be accommodated so that no part of the aircraft extends beyond the line.

       (2) Subject to subsection (3), parking clearance lines may be provided.

       (3) Parking clearance lines must be provided on aprons with unrestricted parking, if it is necessary to:

(a) limit aircraft parking to particular areas; or

(b) ensure clearance from other aircraft or obstacles.

Note   Parking clearance lines may also be provided at an aircraft parking position in conjunction with parking position markings. This marking is useful to depict the area that must remain free of personnel, vehicles and equipment when an aircraft is taxiing (or being towed) into position or has started engines in preparation for departure. All of the area within the parking clearance line is considered to be an aircraft parking position.

       (4) A parking clearance line must be a continuous, contrasting red line that is:

(a) at least 0.10 m, but not more than 0.20 m, wide; and

(b) interrupted 0.9 m either side of a taxi guideline marking that would otherwise intersect with it.

Note   CASA recommends that yellow should be used as a contrasting colour for the aircraft parking clearance line.

       (5) The words "PARKING CLEARANCE" must:

(a) be marked in yellow on any side of a parking clearance line where aircraft are parked;
