3.2.4. RESTARTING THE ENGINE WITH WINDMILLING
PROPELLER
(1) Airspeed for best glide angle ...73 KIAS (1150 kg, 2535 lb)
........................................................68 KIAS (1000 kg, 2205 lb)
..........................................................60 KIAS (850 kg, 1874 lb)
(2) Power lever.................................................................IDLE
(3) Emergency fuel valve ............................... check NORMAL
(4) Alternate air ..............................................................OPEN
(5) Fuel transfer pump.........................................................ON
(6) AVIONIC MASTER ......................................................OFF
(7) ELECTRIC MASTER.....................................................ON
(8) Airspeed .........................................................70-110 KIAS

Note: As long as an airspeed of at least 70 KIAS
is maintained, and there is no major
mechanical engine defect, the propeller will
continue to windmill. After a complete stop
the propeller starts to windmill at airspeeds
above 115 KIAS.
CAUTION: The maximum airspeed for windmilling is
120 KIAS. Higher airspeeds may result in
propeller overspeed.
Note: Restarting the engine with windmilling
propeller is possible at airspeeds between
70 and 110 KIAS and altitudes below
14000 ft pressure altitude.
