→Lift, drag and glide performance
Generally, \[
\frac{\text{horizon distance}}{\text{nm}} \approx \fracsqrt{\sqrtfrac{\text{altitude}}}{\text{ft}}}
\]
* if you have the ridge on your left, fly further out
* usually turn away from ridge, overtake very carefully

=== Lift and drag ===
For the glider to remain in (almost) level flight, it needs to produce a force opposite to the weight. This force is provided by the wings as Lift is generated when air flows across them. Lift by itself is not possible, Drag is also produced along with it.
There are many theories about how lift is actually generated on the wings.
