:classic_rolleyes:

:classic_ohmy: IN FLIGHT why you wanted to engage the starter....as for as in flight no need of starter dear.... Bcoz inflight BLAST OF AIR TURN THE ENG NOT STARTER... 

for the starter turbine RPM just multiply starter gear reduction ratio with the rpm of starter u will get the answer....

I hope it u got my point. 

REGARDS.

Dear at about 9600 RPM engine starter disengaged & engine had enough RPM to damged the starter shaft if bleed is open.so at about 8290 we closed the bleed by releasing start button and starter control valve closed.here is caution if it start  valve light not extinguished in 15 sec after releasing start button shut down the engine.
