Time to refresh my navigation skills, fellow captains! :)I've hereby attached a simple illustration to better explain the problem. Pls use it for reference!Ok, imagine a situation when you're flying in a light GA aircraft with no autopilot and GPS on-board to determine your position along the established route - only "basic" navigation instruments. Now, let's assume that you're flying a flightplan which should take you from the airport / intersection shown as VOR1 on the image to a heading A first. To fly this route, it would be logical to tune the VOR receiver to the frequency of VOR1, and (knowing the distance from VOR1 to A) to keep the VOR needle centered along the course. After some time and patience keeping the needle centered and aircraft balanced against winds aloft, you'll definitely reach point A. This must be simple, indeed!Then comes intersection B, which deviates from your first route (VOR1 -> A) off a couple of degrees to the left BUT you're lucky - you have VOR2 ahead which is abeam your new route A -> B. This seems an easy task too - you'll just need to tune your VOR receiver to a new frequency (VOR2) and follow the path - of course, you've calculated the distance on the map beforehand!Now, comes the problem and question: WHAT if you want to fly from A to C, or even B -> C? Both VORs are scattered along the route, not abeam... How would you find the required heading (not distance) to follow from A/B to C manipulating these two VORs?!? Is it possible?PS: On the image you can see as if A-C follows the same heading as VOR1-A. But pls assume it +10-20 deg. right off the VOR1-A.Thank you very much!

Not the only way to do it, but probably the simplest to follow:Al

Thank you very much, Alan! You're very helpful, indeed!I can start my ENDU-ENAL (Norway) trip now - pure navigation and calculations, and sometimes ded-reckoning - nothing more! :)Btw, your method implies another requirement apart from considering winds aloft - making compass corrections along the route due to magnetic vs. true heading differences, doesn't it?Thanks alot!

Yup. Things are never really that simple when flying the real thing and the wind gets up, although as long as the wind isn't too wild and the distance is not too great, that kind of 'guesstimate' is usually okay. Then again, that's also why you should have a trusty E6-B in your pocket and a decent weather forecast!Al
