Many pilots now carry a GPS (Global Positioning System), an instrument which uses satellite signals to locate its position anywhere on the earth’s surface to within a few metres. A GPS can be a useful navigational aid, but it is not a substitute for a thorough knowledge of navigation theory and practice, and may not be used in the private pilot flight test.
It takes only a few minutes to learn how to read your position, track and speed with a GPS. With a little more practice it may also be used to show bearing, distance and estimated time to a competition goal, to warn if you are close to an SZ, or to give a grid reference for where you have landed (in case you are unsure of your map-reading). A GPS is best left switched on during flight as it takes several minutes to warm up.
