Fuzzy Logic
Tony Verhulst said,
'Ok, answer C says
'The best lift/drag speed with no regard to wind velocity.'.
So, Tony's best lift/drag speed is 50 knots and I'm
flying into a 50 knot
headwind at 50 indicated. And, I'm going ... where?
'A' is the correct
answer, IMHO. Answer 'A', in the above example, would
get you a ground
speed of 25 knots (75 - 50)- you're not going to do
much better than
that. The question, though, is poorly worded.

Hi Tony,
re gittin the mostest out of the leastest into the
winds
when in a gliduh.
'Splain yo comment pls.
I thougjht best L/D into wind was defined to be Still
Air Best L over D speed plus half of the headwind speed
or plus the headwind speed.
What think you?
And, further, it seems one must size up the glide
angle
and impacting or landing site as one goes,
seeking to get best options made for landing .
Legitimate Question:
Is this art, craft, or science? given to addressing
this situation,
or all of the foregoing?
I say,
Fuzzy Logic Rules.
Adapt, adjust, use an estimated set of perameters,
thence
adjust to best outcome considering the difficulty one
finds oneself in and changing facts at hand and in
the changing situation
in his
Gliderplane.
Dancing on clouds,
Keep it up!
