5) Winds affect the power we require when we are in forward flight
The question is badly phrased in that 'winds affect the power we require.......' - to do what?
Any movement of air in relation to the disc will alter the relationship of IF/RAF and therefore the maximum potential of lift will also be affected corresponding to that and pilot induced variations. So you will only need more power if you are trying to maintain datums precisely. This of course assumes W/V is constant in value and origin and it never will be. So the answer is NO.
