AUTOPILOT fEATURES (continued)
Level Mode (Optional)
Level Mode commands the airplane to wings level and zero vertical speed. It
is activated by pressing the blue switch (labeled LVL) at the top center of the
instrument panel. Level Mode may be activated at anytime with the autopilot
engaged or disengaged. Activation is indicated by green LVL and LVL for
lateral and vertical modes respectively. Level mode should not be relied upon if
the autopilot is operating in any failure condition.
Electronic Stability and Protection (Optional)
Electronic Stability and Protection (ESP) provides a control force feedback to
deter the pilot from operating outside a defined envelope. ESP functions only
when the autopilot is operable, but is disengaged. As the aircraft approaches the
defined operating limits, the autopilot servos automatically engage to nudge the
aircraft back to the nominal operating envelope. The pilot can easily overpower
the restoring tendency, and may interrupt ESP with the AP disconnect or
CWS switches. At any time (usually for training reasons), the ESP function
may be disabled from the AUX – SYSTEM SETTINGS page on the MFD.
When disabled in this manner, ESP OFF is displayed. ESP will automatically
re-enable after each electrical power cycle. If ESP has failed, an ESP FAIL
system message will be displayed under the MSG softkey on the PFD.
Expanded Engagement Envelope (Optional)
Expanded engagement envelope allows autopilot engagement up to the pitch
and roll attitudes shown in the autopilot limitations of Section 2. If the autopilot
is engaged at a pitch or roll attitude within the expanded engagement envelope
but beyond the maximum autopilot command limits, the airplane will be pitched
or rolled to the maximum autopilot command limits.
