Thank You man ! After 15 hours going through questions, i finally understand it

[@caribbeanpilot6962]

Wow...finally someone who is a natural teacher. Thank you for this, it answered a lot of questions. I've spent weeks on KZbin going through countless videos trying to piece this all together, and I learned more in this one video, than all of the others ones combined. Very well laid out and explained. Thanks again!

[@ATPLTips]

Wow, I’m so glad to have helped you!! Keep up the hard work!!

[@helikos1]

Going less west is perfectly fine and it's how my instructor would explain things. More east = less west so you can determine whether added or subtracting. Great video Tom.

[@liberteegalitefraternite7804]

Can someone tell me what means the abbreviation GNAV when we break it down. General NAVigation or Grid NAVigation or Global NAVigation ??

[@ATPLTips]

Hi! GNav stands for General Navigation, which compliments the other exam RNav which is Radio Navigation.
