Back 65

NOTE
Turning the FADEC CB switch OFF below 85% NP may result in activation of FADEC FAIL and FADEC MANUAL warnings. If the PMA fails no mesages or tones will occur. NG below 70% engine may flame out.
CAUTIONS
Engine instability or surges can occur over 13,000'
FADEC allows operation above 802 TGT in emergency mode.
Pilot must coordinate throttle and collective or an overspeed/underspeed, overtorque, or overtemp can occur.
Pilot procedures for MAN and FIXED FUEL are the same.
WARNINGS
Regaurdless of switch indication, press to insure in MAN
Failure to switch to MANUAL mode will cause main rotor droop and overspeed.

NOTES
During cold weather starts Oil pressure may exceed MPD range. Remain at engine idle until normal range is attained (2 Min Maximum)
F4 and F5 error codes indicate abnormal signal inputs. Display of these during start does not dictate maintenance.
Pilot monitoring of oil pressure is limiting to operating in the green band of the MPD and checking pressure vs. NG.
