Here you can enter the polar curve of your wing. CompetitionPilot needs the polar curve to calculate several flight parameters, such as the speed to fly, the maximum efficiency speed and the arrival height at the next waypoint or at goal. You can create a list of polar curves.

You can describe your wing polar with good precision by giving CompetitionPilot three pairs of values, each composed of the horizontal speed (Vx, in km/h) and the corresponding vertica speed (Vz, in m/s).

Warning: the last point (number 3) must coincide with the maximum speed of the wing. This allows CompetitionPilot to optimise the calculation of the speed to fly and of the wind.

To simplify entering the data, CompetitionPilot allows to enter the value of the efficiency rather than the vertical speed.

When you modify any of the values, CompetitionPilot draw the corresponding polar curve and calculated the minimum sink rate (Vz min), the maximum efficiency (Eff max) and the corresponding horizontal speeds.

For greater accuracy, expecially at the lower speeds, CompetitionPilot allows you to enter the stall speed (Vs) of your wing.

Entering, for example, 21 km/h the polar curve drawn in the previous figure is changed to:

After modifying a polar curve parameters, you can save it as a new curve or you can replace the old one by means of a specific menu.

When you exit the polar edit page, the polar curve shown is selected.

Touching name with the stylus, a list of the polar curves in memory is shown. After selecting one, its parameter are displayed and the curve is drawn. The polar curve name can be changed by means of the name text field.

Save: the new polar is saved and replaces the old one;

Save as new: add the new polar to the list. The old one is preserved.

Delete: deletes the current polar from the memory.
