Genesys Aerosystems has received an FAA supplemental type certificate (STC) for digital S-TEC 3100 autopilot installations in the Fairchild Swearingen Metroliner turboprop twin, which is used for passenger and cargo operations. Models covered by the STC include the SA226-TC, SA227-AT, SA227-AC, SA227-BC, SA227-CC, and SA227-DC.
The S-TEC 3100 can support third-party electronic flight instrument system (EFIS) displays and integrate its own air-data attitude heading reference system for aircraft without EFIS. Features of the three-axis S-TEC 3100 include automatic trim, envelope protection and alerting, one-button straight-and-level recovery, indicated airspeed hold, altitude preselect, and lateral and vertical navigation. 
“We are excited to add the Metroliner to our vast STC portfolio and provide safety-enhancing technology to the fleet,” said Jamie Luster, Genesys Aerosystems director of sales and marketing.
More than 700 Metroliners were built between 1969 and 1998, when production ended.
