SE192: Airplane State Awareness - Low Airspeed Alerting

Background

The purpose of this Safety Enhancement is to reduce the risk of loss-of-control accidents by having Air Carriers implement low airspeed alerting on existing transport category airplane (TCA) type designs as practical and feasible.

Commercial Aviation Safety Team (CAST) study of 18 loss-of-control accidents and incidents determined that low energy state and stall, resulting from flight crew loss of airplane state awareness (ASA), played a role in 8 events. To further improve early flight crew awareness of a decreasing energy state throughout the U.S. fleet, air carriers should implement existing manufacturer service bulletins to provide low airspeed alerting on existing transport category type designs as applicable.
