This program calculates the distance (radius of action) and necessary headings and time to fly before having to return to a different base than the base of departure but that is moving at a constant speed and course given the moving base's position in relation to the intercepting aircraft, 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.
