downwind turn
wizifoz
No auto throttle or power changes at all, during the 1 minute of turn?
If yes, then its still an open question, neither of us can tell how much due to banked turn and how much due to the effect I am supporting
Well it happens with a hang glider , changes of bank and G as you go round too.
As I implied before, analysis is masked by the impact of various different packets of windspeed as you go round. It is not a problem of 'the ground looks a bit faster', its to do with the need to energise acceleration and momentum against inertia during the turn downwind, and then turning the excess speed back into height during the turn into wind.
Not discernible with big powerful aircraft. very discernible with lack of power and light aircraft
Different question once running straight downwind, then the normal wind gradient helps you flatten/stretch the glideslope,as you descend; trouble is its harder to roll into the turn back, and you may not have the height to do it
Please dont mind me , its surprising my strange concept has not killed me in the last 72 years
PS it occurs to me you might get a different view of what happens if you watch a helicopter or auto gyro and see how those wings go up and down on the way round!
