At the top of the Main Engine Screen are three rows of annunciators. These annunciators makeup a Crew Alert
System (CAS). The top two rows of annunciators are defined by the installer. The bottom row of annunciators is
associated with functions displayed on the Main Engine Screen. Also, at the far right of the bottom row is a
“System” annunciator. If any function found on the System Screen goes into the red or yellow, the “System”
annunciator will blink in the appropriate color. In this way the pilot is alerted of a potential problem and should view
the System Screen for further information and to stop the “System” annunciator from blinking.
If any function found on the Main Engine Screen goes into the red or yellow, the appropriate annunciator in the
bottom row will blink.
If any annunciator found on the top two rows of the Main Engine Screen goes to any color other than white, the
appropriate annunciator will light. If the lit color is red or yellow, the appropriate annunciator will also blink.
To stop the blinking of any annunciator, push any button, or rotate the SELECT knob while viewing the Main Engine
Screen. Also, acknowledging a voice warning using the external “Voice Alarm Control Panel” will stop the blinking
regardless of what screen you are viewing.
Note: To test the annunciators, push and hold the “Exit” button. All available annunciators will light.
2.6 Digital Instruments:
At the bottom of the Main Engine Screen are three areas for digital instruments. The bottom center section may be
switched between Trim (includes Gear and Flaps), Clocks, Flight Timer, Down Timer and Up Timer. Push and turn
the “Select” knob to display the various functions.
If a function displayed on a digital instrument goes in the red or yellow operating range, the digital display will blink
the appropriate color. To stop the blinking, push any button, or rotate the SELECT knob while viewing the Main
Engine Screen. Also, acknowledging a voice warning using the external “Voice Alarm Control Panel” will stop the
blinking regardless of what screen you are viewing.
2.7 External Master Caution and Warning Lights:
A red external Warning Light and a yellow Caution Light (provided with the MVP) may be mounted
in front of the pilot, high on the aircraft instrument panel. These lights provide a heads-up visual
warning. If programmed to do so, the red Warning Light will blink any time the operating level of
any monitored function reaches a red operating limit and the yellow Caution Light will blink any time
the operating level of any monitored function reaches a yellow operating limit.
Pushing any button, or rotating or pushing the Select knob when the Caution or Warning Light is
blinking will acknowledge the blinking and the blinking will stop. Also, acknowledging a voice warning using the
external “Voice Alarm Control Panel” will stop the blinking of the Caution and Warning Lights.
Acknowledging a yellow blinking display will cause the yellow Caution Light to go out. Acknowledging a red
blinking display will cause the red Warning Light to stop blinking and go solid red. At any time another function
reaches a red and/or yellow operating limit the approprate Caution or Warning Light will once again blink.
