Glider Polar Coefficients vs Alt-O-Meter Usage & Stats

Glider Polar Coefficients can be used to easily develop polar coefficients for gliders not found in your glider computer. A few swipe gestures, and the coefficients are solved for any glider. The app can also be used for customizing an existing glider polar. Glider Polar Coefficients is used by glider pilots to adjust the performance capabilities of any glider. The app generates special coefficients used by all glider flight computers. These coefficients are then entered into the flight computer for calculating glide ratios and speeds-to-fly. Simply drag the green minimum sink polar point and red cruise polar point, and the coefficients are calculated automatically. It's that simple.

Alt-O-Meter

Alt-O-Meter uses the barometer (air pressure sensor) in your late-model iPhone or iPad to calculate your precise height above sea level. Great for hiking, skiing, driving through mountain passes, flying, and more! • Reads ambient air pressure for a more precise reading than GPS. • Realistic, retro style. Looks like a classic airplane's altimeter! • Automatically calibrates for local atmospheric pressure. • ...also allows precise user calibration (optional; for advanced users) • Uses GPS hardware in devices that lack a barometer. • Completely free! No ads or in-app purchases.
