Does anyone who is an EASA fan know why they decided to go through the hassle of such a change? Was there a substantive reason or did they just do it because they can?
Not sure, but many would argue that when the blades are turning you are (or should be) in command of it, whether on the ground or not, and should an accident occur you would ultimately be responsible, so it's only fair that your logged hours in command reflect that. Personally I think it's a fairer way of logging time in command.
