CS ADR-DSN.M.760 Advanced visual docking guidance system

(a)Applicability:

(1)Advanced visual docking guidance system (A-VDGS) should be provided where it is operationally desirable to confirm the correct aircraft type for which guidance is being provided, and/or to indicate the stand centre line in use, where more than one is provided for.

(2)The Advanced visual docking guidance system should be suitable for use by all types of aircraft for which the aircraft stand is intended.

(3)The Advanced visual docking guidance system should only be used in conditions in which its operational performance is specified.

(4)The docking guidance information provided by an advanced visual docking guidance system should not conflict with that provided by a conventional visual docking guidance system on an aircraft stand if both types are provided, and are in operational use. A method of indicating that the system is not in operational use or unserviceable should be provided.

(5)Location: The Advanced visual docking guidance system should be located such that unobstructed and unambiguous guidance is provided to the person responsible for, and persons assisting, the docking of the aircraft throughout the docking manoeuvre.

(b)Characteristics:

(1)The Advanced visual docking guidance system should provide, at minimum, the following guidance information at the appropriate stage of the docking manoeuvre:

(i)an emergency stop indication;

(ii)the aircraft type and model for which the guidance is provided;

(iii)an indication of the lateral displacement of the aircraft relative to the stand centre line;

(iv)the direction of azimuth correction needed to correct a displacement from the stand centre line;

(v)an indication of the distance to the stop position;

(vi)an indication when the aircraft has reached the correct stopping position; and

(vii)a warning indication if the aircraft goes beyond the appropriate stop position.

(2)The Advanced visual docking guidance system should be capable of providing docking guidance information for all aircraft taxi speeds encountered during the docking manoeuvre.

(3)The time taken from the determination of the lateral displacement to its display should not result in a deviation of the aircraft when operated in normal conditions, from the stand centre line greater than 1 m.

(4)The information on displacement of the aircraft relative to the stand centre line and distance to the stopping position, when displayed, should be provided with the accuracy specified in Table M-4. Symbols and graphics used to depict guidance information should be intuitively representative of the type of information provided.

(i)Information on the lateral displacement of the aircraft relative to the stand centre line should be provided at least 25 m prior to the stop position.

(ii)Continuous closure distance and closure rate should be provided from at least 15 m prior to the stop position.

(iii)Where provided, closure distance displayed in numerals should be provided in metre integers to the stop position and displayed to 1 decimal place at least 3 m prior to the stop position.

(iv)Throughout the docking manoeuvre, an appropriate means should be provided on the Advanced visual docking guidance system to indicate the need to bring the aircraft to an immediate halt. In such an event which includes a failure of the system, no other information should be displayed.

(v)Provision to initiate an immediate halt to the docking procedure should be made available to personnel responsible for the operational safety of the stand.

(vi)The word ‘STOP’ in red characters should be displayed when an immediate cessation of the docking manoeuvre is required.
