The normal radionavigation beacons, VOR's, transmit a signal that,
when received in the airplane, identify the bearing from the airplane
to the beacon. These beacons are adjusted so the bearing is aligned
with magnetic north, not true north, I believe. So, an aeronautical
map tends to be covered with little compass roses, one at each of
these beacons, and the airways between them are marked with the
magnetic heading to follow.
