Massive Aircraft Diversion (MASSDIV)

What problems are we addressing?

Airlines are sometime faced with the problem of find slots and parking places for their aircraft if weather or other events disrupt operations at their main hub. But which are the most suitable diversion airfields and do they have slots available? In this case an airline needs to plan a sometimes massive diversion beyond local plans, based on business requirements and preferences and provide all users with information in real-time.

The programme

A standard process has been elaborated to support the selection of diversion aerodromes in case of significant reduction of the arrival capacity at a major European airport.  What will make the difference compared to today’s situation will be the ability to plan massive diversion beyond local plans, based on business requirements and preferences and provide all users with real-time information.

The concept involves all partners (ANSPs, airports, airlines, the Network Manager), relies on tool-sharing information among the actors and supports collaborative decision processes to identify the best option to divert aircrafts and to prepare the recovery after the end of the non-nominal situation.

The process, supported by a web-based application, will ensure that the controller and the flight crew are informed, as soon as possible, of the parking availabilities, according to weight category and airline preferences, at alternate aerodromes.  This information will then be updated during the execution of the diversions to reflect as accurately as possible, the remaining parking stands available. The process will also increase the visibility in terms of aircraft localization to anticipate the recovery once the unusual situation is over.
A MassDiv prototype tool was successfully developed with end users.

Expected benefits

The implementation of MassDiv in support of the management of massive diversions would provide the following benefits:

  • Comparing with the processes using manual intervention and telephone calls, MassDiv will ensure an improved efficiency in capturing and sharing diversion data, providing quick and accurate information in support of diversion decisions.
  • The MassDiv process and tool will ease the extension of the diversion plans beyond national borders, to include international airports beside secondary aerodromes.
  • It will provide the opportunity for airspace users to insert their diversion preferences according to the evolution of the operational context.
  • Accurate information on diverted aircraft and capture of airline preferences will support directly the recovery phase once the situation cleared up at the original destination airport.
  • Using MassDiv would have reduced impact on the IT infrastructure for the stakeholders, limited to the access to Internet and availability of adequate browsers (similar as the needs for accessing the NOP).

Programme status

Part of SESAR Project 13.02.03 as well as a Network Manager strategic project which involves the development of an operational MASSIV tool in the NM IT environment, accessible via the NOP.
