There are in-flight situations that can exceed the capabilitiesof ESP-X technology.NOTE: Third party autopilot installations are not supported for ESP-X. ESP-Xrequires Garmin GSA 28 servos.Electronic Stability and Protection (ESP) is an optional feature that is intended tomonitor the aircraft and provide control input feedback when necessary to discourageoperating the aircraft at potentially unsafe attitudes and/or airspeeds. This feature willonly function when the aircraft is above 200 feet AGL and the autopilot is not engaged.When selected, ESP engages automatically when the aircraft approaches or exceedsone or more predetermined airspeed or attitude limitations. Stability protectionfor each flight axis is provided by the autopilot servos, which apply force to theappropriate control surface(s) to discourage pilot control inputs that would cause theaircraft to exceed the normal or "protected" flight envelope. This is perceived by thepilot as resistance to control movement in the undesired direction when the aircraftapproaches a steep attitude, and/or the airspeed is below the minimum or above themaximum configured airspeed.As the aircraft deviates further from the normal attitude and/or airspeed, theforce increases proportionally (up to an established maximum) to encourage controlmovement in the direction necessary to return to the normal attitude and/or airspeedrange.When ESP has been engaged for more than fifteen seconds (cumulative; notnecessarily consecutive seconds) of a 30-second interval, the autopilot can be configuredto engage with the flight director in Level Mode, bringing the aircraft into level flight.An aural “Autopilot” alert is played and the flight director mode annunciation willindicate ‘LVL’ for vertical and lateral modes.
