I flew from KLAX to kord with simbrief flight plan for the 1st time. And found that many fixes were not present. I know it’s billions of them around the globe and implementation of all of them is some task. But in a closed topic I read to suggest if found any missing. So here are few. Will update as I fly to more destinations.
You can use this awesome website to convert Simbrief flight plans into IF-ready ones. It even converts those fixes that don’t exist in IF into sets of coordinates and you can just paste that whole thing to IF without worrying about non existent fixes. ;)
Every month we update our navigation database as well as our airport database with contributions from the community.
So you could add these fixes yourself by working with the airport editing team.
