Cumulus Soaring polar database

Winpilot polar database

Format of .plr files: A text line with label of glider, then mass, water ballast and three sink vs velocity points. Only the sink vs velocity data is used by the app.

*1-35A   WinPilot POLAR file: MassDryGross[kg], MaxWaterBallast[liters], Speed1[km/h], Sink1[m/s], Speed2, Sink2, Speed3, Sink3 381,   179,    98.68,    -0.74,    151.82,    -1.8,    202.87,    -3.9

You can load Polars in 2 different ways:

Method 1: Automatic
Email yourself the .plr file (Winpilot Polar). Tap the file to open it in GliderGPS. Tap 'Yes' to

import the polar.

Method 2: Manual
Tap 'Settings', then tap 'Plane'. Tap the Add button (+). Enter a name for the polar. Tap the + button to add a polar point. The more points the better. The order of the points does not matter. Enter the Speed and Sink rate at each point. Both the Speed and Sink should be Positive numbers. If you use negative numbers, you will get innacurate 'speed to fly' calculations! Tap the 'Speed' or 'Sink' header to change the units. Swipe the 'Swipe to delete', then tap the delete button to delete the polar point.

You must add three polar points to use 'speed to fly' and 'final glide' and 'altitude vs glidepath" calculations.

Make sure the units you choose match the numbers you are entering. Change units by tapping on them.
