FAA extends certification for STG's WEPPS
The Federal Aviation Administration (FAA) has amended its Supplemental Type Certificate approval for STG Aerospace’s Wireless Emergency Primary Power System (WEPPS), to include Boeing 737-300, -400 and -500 series aircraft, in addition to the already certified B737NG series aircraft.
The Wireless Emergency Primary Power System (WEPPS) integrates wireless monitoring, real-time MEL diagnostics, and solid-state operation for managing and powering emergency lighting systems.
WEPPS uses new operating protocols and approved ‘fit-for-life’ non-rechargeable battery modules to replace conventional NiCad battery/charger packs and reduce costs by eliminating the emergency lighting system’s entire maintenance schedule. As a result, there is no need to maintain the batteries on a regular basis and their lifespan is extended potentially to the life of the aircraft.
Peter Stokes, chief Executive, STG Aerospace, remarked, “WEPPS is consistent with STG’s mission to reduce the cost of operating aircraft and to make flying safer and we’re delighted that yet more operators can access the cost-saving technology.
“We’ve applied current proven technologies in an innovative package to eliminate laborious and repetitive maintenance tasks on a critical safety system. It therefore reduces maintenance cost and time for operators, while also delivering exceptional reliability, which is essential in the current economic climate.”
