And imagine the cost of an aircraft rolled over because it needed a pilot instead of an engineer to do the ground run but no one wanted to wait.............
I get the fact that engineers are great - I have relied heavily on their skills, graft and understanding for many years - but, when it comes to rotors running a non-tied down helicopter by someone who hasn't been taught to fly it just in case, then regardless of what the rules say (written by other engineers I suspect) I think it is plain stupid.
