An aircraft VOR is displaying 240° FROM. If variation at the aircraft is 9°W and variation at the VOR is 7°W, what true heading would be required to reach the station, assuming nil wind and ignoring any effects of the turn?
240 FROM means you are on the 240 radial heading away from the VOR. To fly TO the VOR (the station) you would need to fly the reciprocal of 240° (240° - 180°) which is 060°. This is the magnetic heading, but the question asks for (T), so we must use variation.
When using a VOR we take account of the variation at the VOR not the aircraft. Here that is 7°W.
060 - 7 = 053° (T)
