Declaring an emergency

I am currently grade 3 and for a while now I have been trying to figure out how to declare an emergency. Sometimes I do flights so I can practice for emergencies and I am aware there is a communication where you can let ATC know that you are low on fuel and whatever but I always thought you could do it on expert server and be at least grade 3. Anyone know about this…

You have to have been flying for at least an hour I believe it is.

Grade doesn’t make a difference.


To add on to what Chatta said, I would recommend reading this as well.
