Official SEOW

In the West Front winter map we have put airplanes in airfields and airbases in our templates
But there isn´t a symbol of airport in the SEOW map for the airfields(T) and we can´t select a flight of these airfields to edit a mission.

This is the warning message we see

No flights can be scheduled from en route
This airfield is inoperative or under enemy attack!

Why can´t we use it??

Sorry, I found the solution in another post.
Use temporary airbases on

Ok well done
In this map there are several types of airbases:
- Normal Winter airbases (concrete airbases --> White airbase icon)
- Normal Winter Temporary airbases (grass airfields--> Little white cross)
- Temporary Winter Hidden airbases (Hilversum Airbase) does not appear in mini-map.
- Summer airbases (Berck sur Mer) Only summer (Green airbase icon)
- Summer airbases (Tournes Belval) (Winter: Hidden)
