Range and Bearing Calculator
The Range and Bearing Calculator menu command displays a window that calculates and displays the Range, Bearing and Speed Made Good between two waypoints. The Range is the distance between the two waypoints. Speed Made Good is the Range in nautical miles divided by the time difference between the two waypoints. The Bearing is the direction or heading with respect to true north.
To select the two waypoints to be used in the calculations, use the combo boxes labeled Waypoint 1 and Waypoint 2. Click the arrow on the right of the combo box and a list box with all the waypoints will be displayed. The waypoint number will be displayed at the far left of the list box entry, followed by the waypoint latitude and longitude. When scrolling through the list of waypoints the memo corresponding to the waypoint will be displayed in the static box directly above the combo box. To select a waypoint use the mouse or the arrow key to scroll through the list of waypoints. Then either mouse click on the waypoint or hit the enter key to choose a waypoint. To calculate and display the Range, Bearing and Speed Made Good click the Cal push button. To clear the display, click the Clear push button.
As two unique waypoints must be selected for Range and Bearing calculation, this menu command will be disabled until at least two waypoints have been entered. Waypoints may be entered using the Cursor Waypoint Activated menu option or the Waypoint List Window.
