Systems Description
control, depress the center lock button, pull the knob to the open
position, and then release the lock button. Pulling the knob opens the
alternate air induction door on the engine induction air manifold,
bypasses the air filter, and allows warm unfiltered air to enter the
engine. Alternate induction air should be used if blocking of the normal
air source is suspected. Operation using alternate induction air should
be minimized and the cause of filter blocking corrected as soon as
practical.

Engine Indicating

Engine information is displayed as analog-style gages, bar graphs,
and text on the MFD's ENGINE page. When the ENGINE page is not
active or in the case of an electronic display failure (backup mode), all
essential engine information is displayed along the LH edge of the
display. Engine data is acquired by the Engine Airframe Unit which
transmits the data to the Engine Indicating System for display as
described in the following pages.
A "Red X" through any electronic display field indicates that
the display field is not receiving valid data and should be
considered inoperative.
Engine System Annunciations
Engine system health, caution, and warning messages are displayed
in color-coded text in the Crew Alerting System (CAS) window located
to the right of the Altimeter and Vertical Speed Indicator. In
combination with a CAS alert, the affected engine parameter displayed
on the ENGINE page changes to the corresponding color of CAS alert
and the annunciation system issues an audio alert.
For specific pilot actions in response to Engine System
Annunciations, refer to Section 3 - Emergency Procedures,
