2.5 ELECTRONIC STABILITY & PROTECTION (ESP™)
WARNING:
circumstances. There are in-flight situations that can exceed the capabilities
of ESP technology.
Electronic Stability and Protection (ESP) feature 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. This feature will only function when
the aircraft is above 200 feet AGL and the autopilot is not engaged.
CAUTION:
series navigator with a valid terrain database, Low Speed ESP is not
supported and all other ESP modes are functional at any altitude.
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 ten seconds (cumulative; not necessarily
consecutive seconds) of a 20-second interval, the autopilot will automatically engage
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.
