GNav Basics 4a: Convergency 1

Proud to have http://www.aviationexam.com sponsoring my videos! *Re-uploaded due to some audio issues!* This is the fourth video in a series covering the basics of GNav for ATPL students. Originally this video was going to be really long so I cut it into two parts. This first part looks at Earth convergency, and the next part will look at convergency between rhumb lines & great circles! This series of GNav Basics also includes: Video 1: https://youtu.be/qWIQYouJcJk. Refresher on Latitude & Longitude Video 2: https://youtu.be/k4-0Uk2aWRE. The Departure Formula Video 3: https://youtu.be/m5PTKRbhgDE. Great Circles & Rhumb Lines Video 4b: https://youtu.be/QrBlQ4qr9sQ. Convergency (part 2): Rhumb Line and Great Circle Convergency, & Conversion Angle. As ever, if you've found this video helpful then I'd greatly appreciate it if you could give it a thumbs up - and subscribe to the channel if you're not already.
