To obtain your customized Paraglider Performance Comparison table, follow the steps below.
You can read more about this project and some definition of terms that will be used.

1. You can supply data for an Extra Wing
2. Select the typical head wind W, at your favorite site : 0     (In this case: GRw = Lift/Drag) 5 km/h = 3.1 mph 10 km/h = 6.2 mph 15 km/h = 9.3 mph 20 km/h = 12.4 mph 25 km/h = 15.5 mph 30 km/h = 18.6 mph 35 km/h = 21.7 mph 40 km/h = 24.9 mph See also GR_W.
3. Define your vision of an ideal wing (Grade) by setting a relative importance to :
   • Minimum Sink Rate 10 9 8 7 6 5 4 3 2 1 0 ... useful for ridge soaring higher than other pilots.
           Established at no less than 0 km/h = 0 mph 1 km/h = 0.6 mph 2 km/h = 1.2 mph 3 km/h = 1.9 mph 4 km/h = 2.5 mph 5 km/h = 3.1 mph 6 km/h = 3.7 mph 7 km/h = 4.3 mph 8 km/h = 5.0 mph 9 km/h = 5.6 mph 10 km/h = 6.2 mph above the Stall Speed.
   • Maximum GR_W 10 9 8 7 6 5 4 3 2 1 0 ... to be able to go further after leaving a thermal or the ridge.
   • Maximum Speed 10 9 8 7 6 5 4 3 2 1 0 ... to still get decent ground speed in a strong head wind.
4. Select the sorting method :
   • First criterion : Brand Model Rating Min Sink Stall Speed Trim Speed Max Speed Speed Range Max GRw Loading Source Grade
   Second criterion : Brand Model Rating Min Sink Stall Speed Trim Speed Max Speed Speed Range Max GRw Loading Source Grade
5. Select the units for the table : km/h, m/s, kg mph, fpm, lb
6. Select the TFW positioning within the range : No correction 0% 25% 50 % 75% 100%
7. Select the atmospheric conditions :
   • Temperature : No correction -20 C / -4 F -10 C / 14 F -5 C / 23 F 0 C / 32 F 5 C / 41 F 10 C / 50 F 15 C / 59 F (OACI) 20 C / 68 F 25 C / 77 F 30 C / 86 F 40 C / 104 F 50 C / 122 F
   Altitude : No correction 0 m / 0 ft 500 m / 1641 ft 1000 m / 3281 ft 1500 m / 4922 ft 2000 m / 6562 ft 2500 m / 8203 ft 3000 m / 9843 ft 4000 m / 13124 ft
   Pressure MSL : No correction 99.0 kPa / 29.23 in Hg 99.5 kPa / 29.38 in Hg 100.0 kPa / 29.53 in Hg 100.5 kPa / 29.68 in Hg 101.0 kPa / 29.83 in Hg 101.325 kPa / 29.921 in Hg (OACI) 101.5 kPa / 29.97 in Hg 102.0 kPa / 30.12 in Hg 102.5 kPa / 30.27 in Hg 103.0 kPa / 30.42 in Hg 103.5 kPa / 30.56 in Hg 104.0 kPa / 30.71 in Hg 104.5 kPa / 30.86 in Hg 105.0 kPa / 31.01 in Hg
8. Apply filters to reduce the list of wings :
   • Universal Rating : <= = >= 1 1.5 1.75 2 2.5 3
   • Model Name Query - Format :
     Example :     Astral Omega.4
   • Source : Vol Libre Parapente Mag Extra Wing Pilot Manufacturer
   • Age of test (years) : Any 5.0 4.0 3.0 2.5 2.0 1.5 1.0 0.5
9. Interpolation between measurement points : Polar Curve - Natural Cubic Spline
