  • N620201 and N620208 - magnetic track when tracking away from a VOR

    Hello everybody,

    the two attached pictures are showing the same problem with different data.

    Leaving out the explanation of when a DME is more precise in measuring speed, which is clear to me, the issue here is more regarding maths.

    In the first picture, we want to move away from the VOR which, in its location, has a magnetic variation of 14 degrees east. So in order to have a more precise speed, we must track directly away from it, i.e. 360 - 14 = 346 degrees magnetic. But, to make it simple, at the aircraft position we must simply track away following a track of 000 degrees true: corrected for the local variation (14 degrees west this time) gives us a magnetic track of 014 degrees, so the answer is wrong according to me.

    Same issue in picture 2. We want to track away with a 270 degrees true, that is 249 degrees magnetic at the VOR position, but it is 291 degrees magnetic at the aircraft position.

    What did I miss?
    Thanks in advance.
