Calculation for interception

Avatar · 02-07-08, 01:45 PM

Hey fellas,
whats the equation for intercepting a convoy. Lets say you get a radio report of a convoy that's about 100km away, travelling at 7kts, course 030. You are travelling 000 at 18 kts and the convoy is bearing 315 from your position.
what calculation do you need to perform to intercept the convoy? Mostly I estimate it visually with good results, but sometimes I believe that the target got by.
Thanks for the formula, and I hope this isnt too much of a bonehead question

edit: I guess its a physics equation and here are the values you know:
1. target course: 030
2. target speed: 7kts
3. target distance: 100km
4. own course: 000
5. own speed : 18kts
6. target bearing: 315
also, I think you need to change the knots to meters per second, which I dont know how to do. any help appreciated!
