To help prepare for the next tutorial , there are a few things I want to point out on the charts. For basic navigation, there are three things you need to know. All navigation in flying uses radial degrees. A radial is a circle, with 360 degrees spaced out around the circle. These degrees represent compass directions and relationships to other objects.
Navigation aids are basically beacon radio stations.
When you fly, you rarely can make radio contact with your destination airport. Navigation aids help you move between waypoints and also align yourself to approach airports. Some aids carry voice communication, while others just transmit signals. Using the degrees, you can set courses from navigation stations to move on to your next course. I'm not going to get into the differences, but for our purposes they're beacons that function to point us in the right direction.
