Can you add fuel to your company AC before a mission? My plane is starting a mission and it has no fuel. When I go to the EFB and try to add it has no effect. Thanks. 

Been experiencing that also on my latest missions. Must have broken something in the last patch. Can't add fuel prior. But, you can add midflight or prior to flight. Assign a key to add fuel shortcut, which will add 25% fuel. You might encounter crashes if you use the one shortcut to fill up the tank, so don't use that one.

Found a good fix:

 

You can load fuel, when you accept a mission, you will get to a screen with your aircraft in a hangar, then on the right you see the aircraft type and options 'Management' and 'Change Aircraft'. and near the bottom you see the distance and fuel calculation. Remember the number  for fuel. 

Then click on 'Management', this opens the aircraft management screen. Go to the 'Fuel and payload' screen, Then find the 'Manage Fuel' button lower left. You can add fuel like this, for the Cessna 172 I usually make sure I have the fuelnumber of the mission screen + 5 lbs spare.

At first this method was not clear, but after finding it, I have no fuel issues.

 

 

Nothing is broken. As mentioned above, you do it under management pre-flight, same screen where you see the maintenance, there's a fuel tab up tab where you fill up. 

Well dang. How could I have missed that, seriously. Indeed, never seen it. Will try on the next flight.
