In high-performance aircraft with angle of attack/lift sensors, Garmin ESP offers low airspeed or stall protection that reduces the probability of stalling the aircraft by providing a gentle pitch-down control force through the control yoke when the aircraft's wing approaches its critical angle of attack.

The sensor system gathers the real time data, including the wind direction and speed, and the environment data; then by way of the serial port communication, the data are transferred to the Single Chip Microcomputer (SCM); following that the SCM adjusts the sail angle of attack automatically by using the data with the proposed sail angle of attack automatic adjustment algorithm.
