SECTION 4 ADDITIONAL FEATURES
4.1 ELECTRONIC STABILITY & PROTECTION (ESP)
WARNING:
Do not assume ESP will provide stability protection in all circum-
stances. There are in-flight situations that can exceed the capabilities of ESP
technology.
Electronic Stability and Protection (ESP) is a feature that is intended to monitor the
aircraft and provide control input feedback when necessary to discourage operating
the aircraft at potentially unsafe attitudes and/or airspeeds. If enabled, this feature
will automatically arm when the aircraft is above 500 feet AGL and the autopilot is not
engaged, and disarm when below 200 feet AGL.
When selected, ESP engages automatically when the aircraft approaches or exceeds
one or more predetermined airspeed or attitude limitations. Stability protection
for each flight axis is provided by the autopilot servos, which apply force to the
appropriate control surface(s) to discourage pilot control inputs that would cause the
aircraft to exceed the normal or "protected" flight envelope. This is perceived by the
pilot as resistance to control movement in the undesired direction when the aircraft
approaches a steep attitude, and/or the airspeed is below the minimum or above the
maximum configured airspeed.
As the aircraft deviates further from the normal attitude and/or airspeed, the
force increases proportionally (up to an established maximum) to encourage control
movement in the direction necessary to return to the normal attitude and/or airspeed
range.
When ESP has been engaged for more than fifteen seconds (cumulative; not
necessarily consecutive seconds) of a 30-second interval, the autopilot can be configured
to 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 will
indicate ‘LVL’ for vertical and lateral modes.
Level mode as activated by ESP is limited by altitude. ESP will not be able to activate
Level mode until the aircraft climbs above 2000 feet AGL. ESP will be locked out of
automatically activating Level mode after the aircraft descends below 1500 feet AGL
as well. Also note that Level mode as activated by ESP is different than manually
selected Level mode. Manually selected Level mode is not limited by altitude at all.
