ESP
™
engages when the aircraft exceeds one or more conditions (pitch, roll, and airspeed) beyond the normal
flight parameters. Enhanced stability for each condition is provided by applying a force to the appropriate control
surface to return the aircraft to the desired flight envelope. This is perceived by the pilot as resistance to control
movement in the undesired direction when the aircraft approaches a steep attitude or high airspeed.
As the aircraft deviates further from the desired attitude or airspeed, the force increases (up to an established
maximum) to encourage control movement in the direction necessary to return to the desired attitude and/or
airspeed range. Except in the case of high airspeed, when maximum force is reached, force remains constant up to
the maximum engagement limit. Above the maximum engagement limit, forces are no longer applied. There is no
maximum engagement related to a high airspeed condition.
WhenESP
™
has been engaged for more than ten seconds (cumulative; not necessarily consecutive seconds) of a
20-second interval, the autopilot is automatically engaged with the flight director in LevelModeinthepitchand/or

The pilot can interrupt ESP

by pressing and holding the Autopilot Disconnect (AP DISC) switch. Upon releasing
the or AP DISC switch, ESP
™
force will again be applied, provided aircraft roll attitude is within engagement limits.
