PPL/IFR - Allgemeine Navigation | Folge 2

Greetings and welcome to the PPL introductory course with today's episode 2 of the subject General Navigation. Last week we looked at the different types of navigation and also examined what the Earth looks like. We learned about latitudes and longitudes. And what do we need them for? Well, we need to know how to

determine our position on the globe we orbit when flying. For this purpose, a spherical navigation system, or spherical coordinate system, was mathematically placed on the Earth. From this, latitudes and longitudes, great circles, and parallels of latitude were created. This enables us to determine our position precisely. And that's where

we left off last week: latitude and longitude. So now we know it has something to do with geography, latitude and longitude. These are longitudes and latitudes, and we'll take another look at them here. Here's the name again. Geographic latitude is latitude, and geographic longitude would be longitude. Now, of course, we have to

label everything. Just because we've drawn a few lines around the globe doesn't tell us anything yet. We need a clear designation in the form of a label. We have to label every meridian and the parallels of latitude, otherwise it's useless. So, this is how it's done: we have the so- called zero circle, and

we'd like to take a look at that. Here we see the parallels of latitude again; these are the small circles. And we see the equator, which is the great circle. We also know that the meridians from north to south are also the meridians. If we look at the longitudes here on the right,

we can see it quite well. We always have to start from some kind of baseline, and we're now at the point of latitude, not longitude. So, we first want to see on which circle of latitude we are. Regardless of longitude for now, let's start with the latitude circle. The equator serves as the
