On this topic you would have a flight plan to intercept a vor and then fly away from it on a "radial"(using this term loosely as not to get in to a long description about it). When you know you are over a vor and its x miles at xxx degrees from it to the airport you can use the tcan for the dme and the vor for the direction to fly. Each airport has a chart the tells you what radial to intercept it at and how to fly the pattern for landing/ils intercept. I just wish there was a skyvector for dcs. I have a hard time typing what im thinking I am working on a vid tutorial for reading charts and planing flights i will post it in the next few weeks.
