I’m hoping Simbrief will update the app to reflect VFR flight rules. For instance, in the US, VFR flight rules prohibit flights over 17,999 feet. I am able to generate flight plans that takes me up to 41000’. Also, flights should end in 500. A VFR plan should look like 5500’ and never 5000’.
I suspect trying to model flight rules for the whole world is a challenge. I believe Navigraph’s Simbrief team is up to the challenge.
