3 − 4. AIR RESTART − ENGINE
Because the exact cause of engine failure cannot be determined in flight, the
decision to attempt a restart will depend on aircraft altitude, time available,
rate of descent, and potential landing areas.
Do not attempt restart if a malfunction is suspected.
Conditions:
At low altitude or when time is critical.
Procedures:
Close twist grip to cutoff position.
Press start/ignition button immediately.
NOTE
: Pressing the starter button actuates the igniter. If N
1
is 18 percent or above, open
twist grip immediately to ground idle. N
1
speeds of 25 to 40 percent are preferred
for coolest and fastest restarts. Maintain safe autorotational airspeed.
Conditions:
When altitude and time permit.
Procedures:
Perform normal engine start if N
1
has decayed below 18 percent. Refer to
Section IV, Engine Starting.
Recommended airspeed is 60 knots IAS.
Advance twistgrip from ground idle to full open once N
1
reaches 60 −
65%.
Collective pitch: increase as required once N
2
/N
R
are 103%.
