Maximise Range Vs Pitching Down while flying a Glider in a Downward Air Mass
While flying a glider, if I encounter a downward moving air mass (i.e. sink) while on final, should I fly to maximise range (best lift to drag ratio) or should I pitch downward in order to exit the ...

Why the heavier the aircraft is, the higher the airspeed must be to obtain the same glide ratio?
I know weight does not affect glide ratio. But why does higher weight need higher gliding speed?

Relationship between Load-Factor AND Gliding Ratio
I am wondering about the g-load and its relation to the so called gliding ratio.
I read this really good contribution here on this forum:
Does lift equal weight in a climb?
So the g load factor is ...

Can we show through simple geometry rather than formulae or graphs that the best glide ratio occurs at the maximum ratio of Lift to Drag?
For an unpowered glider, can we show through simple geometry involving force vector diagrams, rather than mathematical formulae or graphs, that the best still-air glide ratio is achieved at the angle-...

Why is the L/D ratio numerically equal to the glide ratio?
*L/D is ratio of two forces, lift and drag.
*Glide ratio is ratio of two distances.
Can you explain mathematically how they end up numerically equal and are they always equal?

How does retracting flaps help extend the glide of an aircraft?
As per the video from Smithsonian channel
BA flight 38's captain retracted the flaps of the Boeing 777 by 5 degrees to extend glide, to travel further. Why?

Descending on a given glide slope (e.g. ILS) at a given airspeed-- is the size of the lift vector different in headwind versus tailwind?
We had a discussion with friend and we were talking about if the airplane is on approach and the one is landing with tailwind and the other one is landing with headwind, so both have the same value of ...
