ELECTRONIC STABILITY & PROTECTION (ESP)
Electronic Stability and Protection (ESP) is an optional function on a GFC-700-equipped airplane that uses
the autopilot servos to assist the pilot in maintaining the airplane in a safe flight condition within the
airplane’s normal pitch, roll and airspeed envelopes. Additionally, ESP uses the airplane’s stall warning
system, and the aircraft’s lift computer on certain airplanes, to predict and protect against exceeding stall
angles of attack. If the aircraft’s stall warning system is not operational, ESP Angle of Attack modes and
Autopilot Underspeed Protection functions that depend on that system will also not be functional.
Electronic Stability and Protection is invoked when the pilot allows the airplane to exceed one or more
conditions beyond normal flight defined below:
 Pitch attitude beyond normal flight (+20°, -17°)
 Roll attitude beyond normal flight (45°)
 High airspeed beyond normal flight (Above 260 KIAS or .52M)
 Angles of Attack near stall (if equipped with requisite lift computer)
The conditions that are required for ESP to be available are:
 Pitch and Roll servos available
 Functioning aircraft stall warning system
 Autopilot not engaged
 The Global Positioning System (GPS) altitude above ground (based on TAWS terrain data base)
is more than 200 feet
 Aircraft is within the autopilot engagement envelope (+/-50° in pitch and +/-75° in roll)
Protection for excessive Pitch, Roll, Airspeed, and Angle of Attack is provided when the limit thresholds
are first exceeded, which engages the appropriate servo in ESP mode at a nominal torque level to bring
the airplane back within the normal flight envelope. If the airplane deviates further from the normal flight
envelope, the servo torque will increase until the maximum torque level is reached in an attempt to return
the airplane into the normal flight envelope. Once the airplane returns to within the normal flight
envelope, ESP will deactivate the autopilot servos.
When the normal flight envelope thresholds have been exceeded for more than 10 seconds, ESP
Autolevel Mode is activated. Autolevel Mode engages the AFCS to bring the airplane back into straight
and level flight based on 0° roll angle and 0 fpm vertical speed. An aural “ENGAGING AUTOPILOT” alert
sounds and the Flight Director mode annunciation will indicate LVL for the pitch and roll modes.
Anytime an ESP mode is active, the pilot can interrupt ESP by using either the Control Wheel Steering
(CWS) or Autopilot Disconnect (AP DISC) switch, or simply override ESP by overpowering the AFCS
servos. The pilot may also disable ESP by accessing the Multi-Function Display (MFD) AUX – SYSTEM
SETUP 2 page on the MFD and manually disabling ESP. Once the flight has ended and power is
removed from the G1000 system, ESP will default to “Enabled” on the next power-up.
