WEPPS cleared for Classic 737s
The FAA has granted a supplemental type certificate for installation of STG Aerospace’s Wireless Emergency Primary Power System (WEPPS) in the Boeing 737-300, -400 and -500. The system has also been certificated on the Boeing 737NGs and 767.
WEPPS has been selected by Jet Airways of India and a number of other carriers. It promises significant cost savings by replacing the maintenance-intensive lithium ion batteries that currently power emergency lighting systems with longer-life, non-rechargeable lithium sulphur dioxide units.
The system also uses low-power spread-spectrum wireless technology to check the status of the batteries and all emergency lighting and report back to a compact diagnostic panel wall-mounted at the forward crew station. The latter can be used by cabin staff to check the flightworthiness of the whole emergency lighting system in seconds.
“We’ve applied current proven technologies in an innovative package to eliminate
laborious and repetitive maintenance tasks on a critical safety system,” says STG chief executive Peter Stokes. “It reduces maintenance cost and time for operators, while also delivering exceptional reliability.”
