Hi
Just wondering, at what N2% is it normal to turn the anti collision lights off after shutdown? (Read somewhere around 15%, correct?) Also, is there still a chance that ground personnel could get sucked in moments after shutdown?
Reason I'm asking is because, I've seen personnel walk only a few feet away from the engine after shutdown, and for me it doesn't seem that safe since it's still rotating quite fast.
Don't know how much "suction" it creates once no fuel is powering it.
Thanks
