from the cockpit of an aircraft throughout a docking manoeuvre, the azimuth guidance unit must be:

(a) located on, or adjacent to, the extension of the parking position centreline ahead of the relevant aircraft; and

(b) aligned for use:

 (i) at least by the pilot occupying the left-hand seat; or

 (ii) by the pilots occupying both the left-hand and right-hand seats.

9.120 Azimuth guidance unit — characteristics

       (1) The azimuth guidance unit must provide unambiguous left and right guidance which enables the pilot to acquire and maintain the lead-in line without over-controlling.

       (2) If azimuth guidance is indicated by colour change, then:

(a) green must be used to identify the centreline; and

(b) red must be used to identify deviations from the centreline.

9.121 Stopping position indicator — location

        The stopping position indicator must be located in conjunction with, or sufficiently close to, the azimuth guidance unit, so that a pilot can observe both the azimuth and stop signals without turning his or her head.

9.122 Stopping position indicator — characteristics

       (1) The stopping position information provided by the stopping position indicator for a particular aircraft type must be visible from the intended range of variations in pilot eye height and viewing angle.

       (2) The stopping position indicator must:

(a) show the stopping position of the aircraft for which the guidance is being provided; and

(b) provide closing rate information over a distance of at least 10 m to enable the pilot to gradually decelerate the aircraft to a full stop at the intended stopping position.

       (3) If stopping guidance is indicated by colour change, then;

(a) green must be used to show that the aircraft may proceed; and

(b) red must be used to show that the stop point has been reached; and

(c) for a short distance before the stopping point — a third colour may be used to warn that the stopping point is close.

9.123 Advanced visual docking guidance system (A-VDGS)

       (1) An aerodrome operator may provide an advanced visual docking guidance system (A‑VDGS) in accordance with this section.

Note 1   Advanced visual docking guidance systems include those systems that provide pilots with active (usually sensor-based) guidance information including aircraft type confirmation, distance‑to‑go information and closing speed. Docking guidance information is usually provided on a single display unit.

Note 2   CASA recommends that an A-VDGS should be provided if it is operationally desirable to confirm the correct aircraft type for which guidance is being provided and/or to indicate the stand centreline in use, if more than one is provided for.

       (2) An A-VDGS must be suitable for use by all types of aircraft for which the aircraft parking position is intended.

       (3) An A-VDGS must supply
