engine indications
Not sure if this is in the correct area so advise if not!
I have an aero engine for a well known light single. since overhaul it has been constantly going over the red line and will only just maintain level flight at around 50rpm below red line.
I think it is not safe to be doing this but others in the industry say its fine. However why do we have red lines painted on things (oil temp/pressure etc) if it means nothing? Surely the mountings for the engine can only take a certain torque?
Answers on a postcard please - should the aircraft be grounded?
