provision of turn pads. To specify a taxi route between the runway and the aircraft stand, all the items
mentioned in the previous paragraphs should be addressed.
As the A380 movement is occasional, the operational disturbance could well be acceptable in relation to the
enormous investment for upgrading the infrastructure. As this investment cost will be reflected into the
operational charges of the airport, the other airlines will probably accept the occasional disturbance a
diversion will cause.
To specify a taxi route between the runway and the aircraft stand, all the items mentioned in the previous
paragraphs should be addressed.
Taxiways
If an A380 can-not operate on the taxiway parallel to the runway, taxiing on the runway becomes necessary.
Turning pads at the end of the runway must then be available.
Back tracking on the runway after landing or before take-off is not uncommon and normal practice on many
airports around the world. It is uncommon on airports where parallel taxiways next to runways are provided
and where normally traffic volume is high. Back tracking on the runway could in that case not only cause
operational disturbance (runway is blocked for a longer time), but could also be source of additional runway
incursion risk. Caution should be made for alternate airports where in practice only the occasional A380
movement needs taxing on (part of) the runway.
Taxiway bridges
The taxi route between an aircraft stand and the runway can contain taxiway bridges or tunnels. As
mentioned in paragraph 3.7, taxiway bridges can be critical not only in width but certainly also in bearing
strength. If that is the case, it is wise to define taxi routings that bypass the taxiway bridge or tunnel.
Sometimes this will not be possible as the only route between runway and terminal area will be over the
taxiway bridge / tunnel. In that case, it is advisable to look for a parking position somewhere between the
runway and the Taxiway Bridge / tunnel. In the extreme situation this could be part of the taxiway system or
even a non used runway.
Fortunately, flight diversions are rare. Therefore, the pilot is likely to be less familiar with the airport, its layout
and special procedures. Disorientation is more likely to occur. To prevent mishaps during taxiing,
especially when specific taxi routing have to be followed, guidance by “follow me” may be advisable,
especially in cases other than diversion to a planned alternate.
The design of taxi routes needs to be defined and validated in advance. Co-ordination with the ATC services
and the airlines who intend to regularly file the airport as an alternate is a requirement. The taxi routing,
together with all the other special procedures for the A380, must be published in the appropriate
aeronautical documentation.
3.11 Other items
Besides the mentioned infrastructure items, other issues related to A380 operations at an alternate airport
require resolution.
The following items are a relevant but not exhaustive list.
a) Rescue and Fire Fighting services
The need to upgrade the RFF equipment should be assessed with regard to the national and international
regulations. ICAO, FAA as well as JAA have requirements on RFF services on alternate airports. Alternative
provisions may be derived for full cargo operations. It is the responsibility of the local authority to determine
acceptability of the available RFF services and equipment. The actual availability of the RFF equipment and
services should also be monitored by the aerodrome operator in the frame of its Safety Management
System and notified by NOTAM in case of difference.
b) Snow removal

The blast issues raised in the “runway” paragraph are also valid for snow removal. It is therefore necessary
that airports, which can be filed as an alternate, prepare a plan for runway snow removal based on the
characteristics of the A380 (engine span to be taken into account).
c) Ground servicing
Normally, ground servicing can be achieved with GSE commonly used by other wide body jets (main deck
service). Attention must be given for ground service equipment, which can be specific for A380 operations,
for example:
 A capable tow truck and suitable tow bar at alternate airports where towing the aircraft is unavoidable
 Suitable de-icing equipment
Some other items of interest
 Stairs suitable for large aircraft (around 5m height)
 GPU (minimum twice 90KVA)
 Refuelling height similar to 777
In the case of a filed alternate, the servicing of the aircraft, its passengers, cargo and baggage should be
prepared in advance; the airline should ensure the availability of the relevant handling equipment.
