Radius of Action Returning to Alternate Base

 Tip: To toggle full-screen mode in Google Chrome, Microsoft Edge, Firefox and Opera the primary keyboard shortcut is F11 on Windows and Ctrl + Command + F on macOS.
 


This program calculates the distance (radius of action) and necessary headings and time to fly before having to return to an alternate base that is at a certain distance and bearing from the fixed base of departure given wind conditions and the fuel time available.

Note: Radius of Action Calculations are also known as Point of Safe Return Calculations (PSR).

Instructions:
Input data in the white colored fields in the desired unit column and press "Calculate". Results will then be displayed along with a visual representation. If inputs are invalid then no results or visual representations will be displayed.

For a random example click on "Test" and then "Calculate". You may click "Test" as many times as you wish to generate an infinite amount of examples.

To clear all fields press "Reset".
