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 normal 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 normal attitude and/or airspeed range, the force increases (up to an
established maximum) to encourage control movement in the direction necessary to return to the normal 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.
WhenESP
™
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 LevelMode,bringingtheaircraft
into level flight. An aural “Engaging Autopilot” alert is played and the flight director mode annunciation will indicate
‘LVL’forverticalandlateralmodes.
The pilot can interrupt ESP
™
by pressing and holding the Autopilot Disconnect (AP DISC)switchortheControl
WheelSteering(CWS) button. Upon releasing AP DISC or CWS, ESP
™
force will again be applied, provided aircraft
roll attitude is within engagement limits. ESP
™
can also be overridden by overpowering the servo’s mechanical
torque limit.
