I have always found the flight conditions menu confusing
For Weather and Time
What’s the difference between Live, Preset and Custom ?
I guess Live is the current weather conditions and current time - but don’t know how Preset and Custom differ. Also if I switch on Live - the error message should not appear I hope
For Air Traffic
What’s the difference between Live, AI and Off ?
I guess Off switches off live air traffic, but don’t know what the difference is between Live and AI
I am on single player - so the setting for multiplayer will always be off
As this is a public forum, full of experts, I will preface my reply with “as I understand it”.
Live weather is the weather at the time you open the simulator, as read from the internet, the time can be live or not, it does not affect the weather, which is always the weather at the time in the real world, not the time set in the simulator.
A weather preset is one of the fixed choices, such as “Clear Skies”
Custom weather is what you may have created and saved as one of your own choices of weather.
Live air traffic reads the real world traffic data from the internet and uses that to place AI aircraft.
AI traffic uses the simulator to place aircraft.
Off places no AI aircraft.
