Welcome over Flanders fields,
Hobomaniac!
The real air war with single seat fighters involved began only in 1916.
The early areas of heavier fighting were the battle of the Somme, and the fighting for Verdun.
If you want to fly as a French and "shoot Germans", I recommend the Verdun area in spring or summer 1916.
You can generally say, that the air war will get busier and harder from month to month - 1918 is hell
in many areas, and the aircraft have devolped from Fokker Eindecker or Morane Parasol, to Fokker D.VII
and SPAD XIII - huge differences.
So if you enlist a new pilot, click on the "Manual enlistment" button in the lower right corner;
then select flying for France, and flying a fighter.
Now you can go through all the fighter units, or Escadrilles, you have in WOFF.
You can click the time arrows for years, months and even days with every unit, and thereby see,
where they were based, when they moved elsewhere, which planes they had at each time,
which morale and aces etc. etc.
That way, you should be easily able to find yourself a good unit, area and time, where you can go
and "shoot Germans".
Enjoy it (but take care: they'll shoot back)!
