Summary
Description Polar curve 1.jpg |
English:
Polar curve for a glider, showing glide angle for minimum sink rate. The origin of the graph is where the airspeed axis crosses the sink rate axis at zero airspeed and zero sink rate. The horizontal line is tangent to the top of the polar curve. That tangent point indicates the minimum sink airspeed (vertical line). The sink rate increases to the left or right of this point, corresponding to a lower or higher airspeed. This minimum sink airspeed has the lowest possible rate of sink, and allows the longest possible glide time before landing

Commons:Media for cleanup
for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with
{{

.
It is recommended to name the SVG file “Polar curve 1.svg”—then the template Vector version available (or Vva ) does not need the new image name parameter. |
This graph image was
