Managing UDV Fixes
You can use the Fixes window to manage the fixed points that appear on the map. The Fixes overlay shows fixed points of reference that are established by and continually updated with, the latest data from the FAA. Fixes are determined using visual and electronic methods to pinpoint the position of an aircraft in relation to the Earth's surface. They are calculated by taking measurements of distances or angles from known reference points.
