Abstract

Many airlines provide wifi on board to distribute media of the entertainment system to passenger devices during their flight. Therefore passengers could install the airline's application before coming on board of the aircraft. If the airline's application is enhanced by a data transfer feature, this infrastructure of passenger devices can be used as a new way of transferring data to the airline as shown in the following figure.

OUTSOURCED DATA TRANSFER FROM AIRCRAFT WITHOUT ONBOARD TRANSMISSION INFRASTRUCTURE

The technical field of this idea concerns e.g.

- Big Data: Collecting and analysing data is a trend. Being used for predictive maintenance, statistics, planning but as well as enabler for services, airlines are interested in aircraft and flight data of their fleet and use server farms to analyse and find patterns to improve service and operation.

- Cabin e-Ops: More and more airlines equip their crew members with tablet computers. Applications can help crews with maintenance manuals, reports, planning or passenger lists. Integration with aircraft data is planned but not yet developed. Integration with airline processes are already implemented at some airlines.

- Inflight Entertainment: Bring your own device (BYOD): Passengers are motivated to bring their own devices on board, where entertainment videos etc. are streamed directly on the personal devices of passengers. Therefore a special application needs to be installed on the passenger’s device.

There exists well known state of the art: SatCom: A satellite link enables internet connection on board of aircraft. A satellite modem needs to be installed on aircraft and a complex firewall server needs to be maintained. GroundLink: Alternatively to satellite links, a connection can be established directly to ground stations. This works as long as the aircraft flies over equipped land, usually there is no connection above oceans, mountains, etc. GateLink: Usually a wireless LAN connection which is enabled on at the airport gate during turnaround times and used to exchange high amount of data. The present author sees that there is a lot of data exchange between aircraft and ground servers: status reports, maintenance data, entertainment system uploads etc. All these data transfers share access via on-board infrastructure and thus compete for transmission time. Additionally, internet services for passengers also use existing connections with a high priority and limit availability of data links. Recently, a new use case gains importance: airlines involve in big data analysis and show interest in all avail...
