ESP is automatically enabled above 200 ft AGL using GPS altitude. If a Loss
of GPS Integrity (LOI) occurs ESP will default to enabled, however low speed
ESP functions will be disabled.
As the aircraft deviates further from the normal attitude and/or airspeed,
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. For all conditions except for high airspeed, once 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 limit associated with high airspeed.
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.
In the event of unexpected autopilot behavior, the pilot can interrupt ESP by
pushing and holding either the Control Wheel Steering ( CWS ) or Autopilot
Disconnect ( AP DISC ) switch. Upon releasing the CWS or AP DISC switch,
ESP force will again be applied, provided aircraft attitude and/or airspeed are
within their respective engagement limits. ESP can also be overridden by
overpowering the servo’s mechanical torque limit. Although the pilot may
physically overpower the ESP forces prior to the ‘Engaging Autopilot’ message,
the pilot must recognize when the autopilot is engaged and not attempt to
physically override the autopilot.
If flight maneuvers exceeding the normal ESP envelope are intended, the
feature can be disabled. ESP can be enabled or disabled on the ‘Aux - System
Setup’ Page on the MFD.
