Sagem's WEFA system to transmit maintenance data on A320 family jetliners is certified

Boulogne-Billancourt, February 24th, 2015

Airbus has certified the WEFA system made by

Certification du système WEFA de Sagem pour la transmission de données de maintenance sur la famille A320

Sagem (Safran), intended to remotely track the situation and maintenance status of Airbus A320 commercial jetliners. The certification from Airbus opens a potential market of several thousand aircraft for Sagem.

Sagem's WEFA system (Wireless Extension For ACMS/Aircraft Condition Monitoring System) allows airlines to remotely manage their flight data using a secure Internet connection, and therefore plan ahead for maintenance operations. Featuring a "plug and play" design, the WEFA system calls on the secure radio transmission of maintenance data collected in flight by the FDIMU (Flight Data Interface Management Unit), also supplied by Sagem.

The core of the WEFA system is a 3G radio network for data transmissions between aircraft and with airports. It offers extensive processing capacity for data from the aircraft's avionics suite, prior to transmission to the ground to speed up maintenance operations. It calls on Sagem's proven encryption expertise.

Sagem's WEFA system meets the emerging needs of the air transport industry, since it supplies data for preventive maintenance, improving flight safety and enabling airlines to lower their operating costs.

A pioneer in aircraft monitoring and maintenance systems, Sagem supplies Aircraft Condition Monitoring Systems (ACMS) on the Airbus A300, A310, A320, A380, A400M and A350 XWB.
