RE: Downwind Turns!!
Throttle and elevator usage should be identical with upwind, downwind, and crosswind turns. The problem occurs as stated before, when the person controlling the aircraft tightens the turn to keep the ground track the same as the up wind turn. This causes a steeper bank which in turn requires more elevator to maintain altitude, which in turn slows the airspeed. The slower airspeed is not noticeable as the ground speed has increased. Other than gusts and turbulence the aircraft is oblivious to wind, we only notice the wind because of the effects seen with our ground track and speed. Think of it like a boat on the Mississippi. Lets say the river is flowing at 5Kts (wind) and you are traveling at 5 Kts indicated that is a total of 10 kts down river. If you make a turn up river and don't change the throttle does the bow raise up and you suddenly are going 10kts? No you are still going 5 kts indicated and other than the fact that you are not moving in relation to the shoreline nothing has changed. You are basically in a giant mass of air all moving at a set speed and the A/C is flying in it. Wind or no wind the A/C doesn't care. Again this all excludes gusts and turbulence.
