For ground starts only, the ignition duty cycle is: __ attempted starts, __ min off, an additional __ attempted starts, and __ min off.
For ground starts only, the ignition duty cycle is: 3 attempted starts, 3 min off, an additional 3 attempted starts, and 23 min off.
Explain “Cruise Flat”
As the throttles advance towards MIL, nozzle position decreases towards 0% until approximately 85%. At this point, the nozzle remains fixed at 16-22% until the throttle is advanced to where the nozzles begin to close towards zero. Best cruise performance is here in cruise flat.
