Hi all
LIM-70 P 1/2
STARTER
‐ 3 consecutive cycles : 2 cycles of 2 min each, followed by a 3rd cycle of 1 min .
‐ Pause between start attempts : 15 s.
-Cooling period, following 3 start attempts or 4 min of continuous cranking : 30 min .
‐ No running engagement of the starter, when N2 is above 10 % on ground, and 18 % in flight.
My question over here is that the time "4 minutes" mentioned in the FCOM is RECOMMENDED, MINIMUM or the MAXIMUM time.
