Thank you for your posts.
I am glad that you mentioned turboprop run up, I was wondering about this subject.
Do you usually perform turboprop (even for piston engine) run up at test cell with the prop removed or installed?
Is it possible to approach (but not really close) a turboprop (even aircraft with piston engine, and not in test cell) with open cowls and in THRUST REVERSE to have a closer look to the engine?
I read somewhere that the fan of certain turbofan engine can be strapped or locked to perform engine run up (may be just on idle?).
Is this valid only for the old engines or even for the recent engines?
Is this method still used?
Feedback appreciated.
Thank you.
