          Main Variables
     
          Wind Direction (WD)   [o]    
          Wind Speed (WS)   [knots]   [km/h]     [sm/h]
          Heading (HDG)   [o]    
          True Airspeed (TAS)   [knots]   [km/h]     [sm/h]
          Course (CRS)   [o]    
          Ground Speed (GS)   [knots]   [km/h]     [sm/h]
 
Correlated Variables
Cross Wind Component (XWC)
  [knots] - L / + R   [km/h]     [sm/h]
Head Wind Component (HWC)
   [knots] - T / + H   [km/h]     [sm/h]
Crab Angle (CRA) or Wind Correction Angle (WCA)
  [o] - L / + R    
Drift Angle* (DRA)
  [o] - L / + R    

      Unknown Variables * Note: The Drift Angle here is the angle that the aircraft would drift if the Crab Angle or
   Wind Correction Angle were not applied. If the Crab Angle is applied the aircraft's Drift
   Angle is the same as the Crab Angle but in the opposite direction.
      Known Variables

     Specify the unknown variables then enter any field that is white and see the results on the green fields. Correlated
     variables are calculated as a result of the main variables above. XWC and HWC may be entered in place of WD and WS.
     WD and WS will be calculated as a result of XWC, HWC and CRS. If entering XWC and HWC be sure to have the CRS
     set first. Showing decimal places does not affect the precision used in the calculations. Since results are calculated as data
     is entered, be sure to enter all data before interpreting results.

     Enter the CRS then enter WD and WS or XWC and HWC. When entering WD and WS the XWC and HWC will be calculated
     based on the CRS. When entering XWC and HWC the WD and WS will be calculated based on the CRS.

     Enter any two fields (i.e. Time, Speed, or Distance) in the box for the appropriate unit being used then press "Eval" for
     the remaining field and get that field's result.

  weight per volume (specific weight) based on temperature          [oC]      [oF]   

Note: results for weight per volume (specific weight) are typically accurate up to one decimal point only. Due to the inherent variability of fuels even the same type of fuel may vary greatly depending on its origin. The figures provided here are a very rough estimate.
Values based on FAA-H-8083-1A, Aircraft Weight and Balance Handbook Chart, page 7-13.
  protect type of fuel weight per volume parameters*  

     Enter any two fields (i.e. Time, Fuel Flow, or Fuel) in the box for the appropriate unit being used then press "Eval" for
     the remaining field and get that field's result. Any calculation involving weight will be based on the Weight per Volume
     parameter for the fuel selected. If changing the type of fuel after Fuel Flow or Fuel has been entered weights will
     automatically change and volumes will remain constant.

   *I have allowed the possibility of changing the fuel weight parameters in case you have a more precise value. Be very
     cautious when doing this.
