Magnetic Course

Enter any two fields (i.e. True Course, Variation or Magnetic Course) then press "Eval" on any remaining field for that field's result.

Magnetic Heading

Enter any two fields (i.e. Magnetic Course, Wind Correction Angle or Magnetic Heading) then press "Eval" on any remaining field for that field's result.

Compass Heading

Enter any two fields (i.e. Magnetic Heading, Deviation or Compass Heading) then press "Eval" on any remaining field for that field's result.

True Heading

Enter any two fields (i.e. Magnetic Heading, Variation or True Heading) then press "Eval" on any remaining field for that field's result.

Wind Triangle

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.

Cross / Head Wind Components

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.

Time - Speed - Distance

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.

Fuel - Time - Fuel Flow

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.
