8. Verify FADEC Auto/Manual Switch (on dash) is in AUTO

Engine Start

• Advance Throttle to IDLE position
• The Start Switch must be activated within 60 seconds of advancing the throttle or the engine will not start. To reset, set Throttle to OFF and toggle the FADEC Circuit Breaker Switch OFF, then ON. Then restart the procedure.
• Hold Start Switch for two seconds then release
  • Pilot MFD may flicker as voltage drops during start process
  • Acknowledge cautions as necessary
• Wait for NG to stabilize between 63-65%
• DC Generator Switch – ON
• AC Generator Switch – ON
• Essential Bus Switch to RUN
• Fuel Boost Switch - ON
• Particle Separator Circuit Breaker – IN
• Advance Throttle to OPEN
  • Acknowledge cautions as necessary
  • Wait for TGT and RPM to stabilize
• Set MPD Selector Switch to display NR/NP
• Increase NP/NR to 100% using the RPM Trim Switch
  • Increase until one amber chiclet is visible on the NR VSI

Warnings, Cautions, Advisories

Acknowledgement and Recall of Cautions and Advisories

Pressing the REC/ACK switch to the ACK position will delete the message from the screen.

When an advisory has been acknowledged, it will stay in memory as long as the advisory condition exists.

Pressing the switch to the REC position will return any stored caution or advisory messages to the display, up to a total of five cautions and advisories.

If more than five messages are active at one time, only five messages will be displayed plus a note of how many more messages are yet to be displayed.

The total number of active advisories is displayed to the right of the letter A at the bottom of the screen.

INFO
When a warning condition occurs, the warning is displayed, accompanied by a warning audio. The FADEC FAIL warning consists of a high/low tone. The LOW RPM ROTOR warning consists of a continuous whoop. The audio signal for all other warnings is a continuous three “bongs” per second. The audio signal can be silenced by moving the REC/ACK (recall/acknowledge) switch on the MFK to the ACK position

The Full list of Warnings Cautions & Advisories is included in the Appendix

INFO
Aircraft Caution, Warning, and Advisory messages will not display on the CPO (left) LWCMFD while in the L2MUM mode.
