hi Hazel
just imagine you are flying the glider with only 4 instruments
altimeter, ASI, VSI and compass
so you are "connected" to air and have no clue of wind or groundspeed
so how will
The speed for max angle of climb reduce with headwind
???
when you do not know the wind ?
Besides gliders NEVER climb.
They constantly descend even in a an updraft. Right ?
