WEFA: Enabling a closer loop between aircraft and airline

Wireless Extension For ACMS

How WEFA works

WEFA is composed of the WEFA station (ground software application) and WEFA card (Smart PCMCIA Card). While the aircraft is flying, data collected by the ACMS (Aircraft Condition Monitoring System) are stored in the WEFA card. As soon as the aircraft is on the ground, communication initializes between the WEFA card and the WEFA station installed on the airline server, through a 3G+ connection, using available mobile network.

Collect your aircraft data with no effort

The huge benefit of WEFA is to allow a continuous and fully automated recovery of aircraft data without human manipulation, reducing costs, delays, and risks of data loss. Aircraft data is available right after landing, enabling pilot's air safety reports investigation right away, while allowing a data recovery rate of 100 %.
