Calculate Point B

This calculation is done when you know the coordinates of a starting point, and you have either

•a distance and a bearing to a second point

•a speed, time of travel and bearing to a second point

Header information

This information is used for both of the calculations - 

•A : Magnetic Variation - this default is the magnetic variation for the default station (in this case Kommetjie).  The variation can be changed if necessary

•B : Filter for the Points table - This is an optional item, but using it helps find the required point.  Type in a word(s) to filter on and then press ENTER

•C : You must say whether the bearing is a True (default) or a Magnetic bearing

•D : Click on the CALCULATE button to perform the calculation

•E : The result of the calculation will be displayed in the Answer box

oThe coordinates of Point B as Decimal Degrees

oThe coordinates of Point B as Degrees and Decimal Minutes

•F : CLEAR button to clear all the information on the form

•G : GPX button will create a GPX file with Point B as a waypoint.  This can be imported into Google Earth Pro and sent to a Rescue Vessel

Speed, time and bearing

•A : Speed - the average speed the vessel will travel in knots

•B : Time - the number of minutes they will travel for until they reach Point B

•C : Bearing - the bearing they will travel on

•D : True or Magnetic - which kind of bearing has been given

•E : CALCULATE button - click on this button to perform the calculation

•F : The answer will appear in the Answer box

oCoordinates of Point B as Decimal Degrees

oCoordinates of Point B as Degrees and Decimal Minutes

•G : GPX button - click on this button to create a GPX file with Point B as a waypoint

•H : CLEAR button - click on this button to clear all the information on the form
