Depends on prevailing wind strength and direction, both of which may be variable.

The actual heading of the aircraft may not be the same as the resultant course flown.
That is correct. For decent accuracy, wind speed needs to be taken into account (and the pilot needs to compensate accordingly in his heading). No one said it was easy

It is triangulation "triangulation is the process of determining the location of a point by measuring angles to it from known points at either end of a fixed baseline, rather than measuring distances to the point directly. The point can then be fixed as the third point of a triangle with one known side and two known angles."

The range from aircraft to beacon (at both points of measurement) becomes known by using the law of sines. We have all three angles known in the triangle and we know one side (the distance traveled between the measurements).

even though you have your airspeed with dymamic weather modling you don't know your ground speed (or as AshesHouse has pointed out) any effects of drift. To determine that you'ld probably have to use visual reference to land marks (unless you have a Nordon bomb site of course) in which case your using good old map and compas and dead reconing to determine your location.
As I mentioned above in my reply to him, of course these things must be known to some degree. The accuracy of the method depends on getting those tricky variables right. There's no wind in IL-2 which is a shame. Maybe those wind and turbulence mods work, have to check it out.

If you have visual references you'ld be quicker ploting your bearing from the NDB onto your map and looking for landmarks along that line.
I would agree with that Though if can't see landmarks for whatever reason, or just don't have visual references, maybe it's worth a shot.

The lower the wind and the higher the aircraft speed, the more accurate it should be, right? Because the ratio will determine how much movement was from aircraft and how much was wind affected. Assuming we don't have a grip on the wind.[/QUOTE]

Oh but this IS the fun! We're pouring fun INTO it


Question to all - is there any way of seeing how the wind is blowing relative to the aircraft? Both when seeing the ground (not having a map to compare to) and when flying without any visual on the ground. How did people figure this out in flight way up there?
