Hello,
Going direct to an airport will be difficult, as sometimes you will be going into conflicting traffic ect. Using waypoints, you can plan your journey following traffic and setting yourself up correctly for the approach into the airport of your choice.
This video will help your understanding. It’s ok the Infinite Flight official channel.
Ok thank you for your reply. But still what confuses me is that waypoints are scattered all the way and next to each other so what is the criteria of selecting the waypoints in FL.
It just gives you a more realistic and accurate. Filing a flight plan which goes directly to the airport isn’t good to follow. It can set you up better for an approach. There are no guidelines to Flight planning you can do what you want ! It’s simply for you to follow ;) Hope that’s what you’ve been after :)
