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).

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".
