1.
2.
3.
Pressing Esc twice will take you back to your flight.
If you want to change the unit, you have to configure weather manually :
Then you can choose the unit and your choice will be kept if you revert to real world weather.
X-plane 11 manual can be found online by googling X-plane 11 manual :

It is also available offline here :

Can you edit the tags you chose for your question, so that this thread can be found more easily by other users, and thus be more useful?
Regards,
