Additional Features
When ESP has been engaged for more than ten seconds (cumulative; not necessarily
consecutive seconds) of a 20-second interval, the autopilot can be configured to
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.
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.
NOTE: If AGL height data is unavailable (i.e., GPS altitude or terrain data is
unavailable), automatic engagement of Level mode is not supported.
The pilot can interrupt ESP by pressing and holding the Autopilot Disconnect
/ Control Wheel Steering (AP DISC/CWS) switch. Upon releasing the AP DISC/CWS
switch, ESP force will again be applied. ESP can also be overridden by overpowering
the servo's torque limit.
ESP is configured on the Electronic Stability Configuration page in Configuration
Mode. Refer to the Installation Manual for more information on configuring ESP.
ESP is enabled or disabled from the Automatic Flight Control System (AFCS) page or
using an externally wired ESP discrete switch.
Enabling/disabling ESP using the G3X Touch Autopilot Interface:
1) From the PFD, touch the Autopilot Status Box. The Automatic Flight Control
System page is displayed.
2) Touch the ESP button on the Automatic Flight Control System page to
enable/disable ESP.
ESP can be configured to be automatically enabled on system power-up.
