over some great secret hidden in some abstract paper I found on the internet, is considered "gash",...?
I think aa777888 found it and it is hardly abstract but you are too clever and knowledgeable to learn anything new....
The answer to my question was - take the crosswind from the left (or the same side as your power pedal is). Why? Because weathercock effect (the desire for the aircraft to point into wind) will require non-power pedal to overcome, meaning a lower Tq demand and a reduction in power required (important at high AUM and high DA). If you take the wind from the non-power pedal side, you need more power pedal to stop the weathercock and therefore more Tq overall.
There, that wasn't too abstract was it?
Gash is an attitude of mind - it's the opposite of professional. A bit like a closed mind not willing to embrace new knowledge compared to one striving to learn and improve.
