ADR.OPS.D.025 Aircraft stand allocation

RESPONSIBILITY FOR AIRCRAFT STAND ALLOCATION The overall responsibility for aircraft stand allocation normally lies with the aerodrome operator. The aerodrome operator may also decide to delegate the aircraft stand allocation to an air operator or to an organisation responsible for the provision of groundhandling services if they have a dedicated terminal or an apron area. However, the aerodrome operator remains ultimately responsible for ensuring that safety is maintained.

COMMUNICATION OF THE ASSIGNED AIRCRAFT STAND TO THE PERSONNEL DIRECTLY RESPONSIBLE FOR THE MANOEUVRING OF THE AIRCRAFT The information on the stand assigned to arriving aircraft should be communicated to the personnel responsible for the manoeuvring of arriving aircraft:

(a)through a radio frequency; or

(b)through data link communication; or

(c)with a ‘FOLLOW ME’ vehicle; or

(d)with marshalling hand signals; or

(e)with a visual docking guidance system; or

(f)any combination of the above.

CONSIDERATION OF AIRCRAFT CHARACTERISTICS FOR AIRCRAFT STAND ALLOCATION The following aircraft characteristics are to be considered for the allocation of a stand:

(a)Fuselage length The fuselage length is relevant for:

(1)the dimension of the movement area (taxiway holding bays and aprons), passenger gates and terminal areas; and

(2)the clearance at the aircraft stand.

(b)Sill height The sill height is relevant for:

(1)the operational limits of the passenger boarding bridges (including the number of passenger boarding bridges needed);

(2)the mobile steps; and

(3)the access of vehicles for passengers with reduced mobility (PRM).

(c)Tail height The tail height is relevant for:

(1)de-icing/anti-icing facilities; and

(2)protection of the aerodrome’s obstacle limitation surfaces.

(d)Wingspan The wingspan is relevant for:

(1)the dimensions of aprons and holding bays;

(2)the stand selection; and

(3)the clearance at the aircraft stand.

(e)Wing tip vertical clearance The wing tip vertical clearance is relevant for apron and holding bay clearances with heightlimited objects.

(f)Cockpit view The relevant geometric parameters to assess the cockpit view are the cockpit height, the cockpit cut-off angle, and the corresponding obscured segment. The cockpit view is relevant for maintaining a view of the stand entry guidance.

(g)Engine characteristics The engine characteristics include engine geometry and engine airflow characteristics, which may affect aerodrome infrastructure, as well as aircraft groundhandling and the operations taking place in adjacent areas which are likely to become affected from jet blast.

(1)The engine geometry aspects are the following:

(i)the number of engines;

(ii)the location of the engines (span and length);

(iii)the vertical clearance of the engines; and

(iv)the vertical and horizontal extension of possible jet blast.

(2)The engine airflow characteristics are the following:

(i)idle and breakaway thrust; and

(ii)inlet suction effects at ground level.

PARKING AIDS The following are considered parking aids:

(a)a visual or an advanced visual docking guidance system;

(b)a marshaller.

FACILITIES SERVING THE AIRCRAFT STAND The following facilities may have an impact on the allocation of aircraft stand:

(a)passenger boarding bridges;

(b)fixed ground power supply units;

(c)air-conditioning units;

(d)location of fuel pits;

(e)equipment parking areas.
