Going from one place to another is not difficult, | Going from one place to another is not difficult, we do it every day. We look around and go from one place to another. We see and recognise the landscape and landmarks around. We are familiar with where we are so it is easy to find our way around. | ||
If | If we go to a place we are not familiar with we would buy (download) a map to find our way around. There are street names and specific buildings we can orientate ourselves with. On our Swiss knife we have a mini compass we sometimes use to orientate the map North. | ||
Visual navigation is possible when | Visual navigation is possible when we are low enough and when the weather allows it. To orientate ourselves we use a map and a compass. Movement goes a lot faster as walking so to see where we are we have to update our position on the map often or else we would get lost quick. | ||
When there are not enough visual clues to know where | When there are not enough visual clues to know where we are we will have to rely on our equipment on-board to navigate. Lucky there is a rack of tools in our aircraft to help us find our way, even at night and high up in the sky. We just have to know how to use it. | ||
Instead of relying on visual landmarks (roads, rivers, churches, towns) radio navigation relies on radio beacons. Radio beacons can be seen with the right equipment, from far away and independent of the weather. The position of radio beacons is clearly marked on navigation maps. Radio beacons are placed near airports, can be aligned with runways and can be placed in remote areas so to mark a route over them. | Instead of relying on visual landmarks (roads, rivers, churches, towns) radio navigation relies on radio beacons.
