Q

EP: Engine Restart In-Flight

A

Procedure:
-Adjust collective to maintain 90-107% NR

*52 KIAS with minimum NR allow pilot more time
-Close throttle
-FUEL VALVE switch ON
-STARTER button Press and Hold
*If N1 is below 30% throttle shall be modulated to prevent exceeding TOT
-Throttle to Idle
-TOT modulate throttle to maintain 716-768 or 716-826(If red triangle)
-Throttle advance smoothly to full open position
*If restart unsuccessful abort and secure engine
