Corsaire31, I just have a look back to the rules and I haven't found the rule you are talking about ...

Does it means if there are 2 patrols in a day in the campaign, we must fly 2 patrols the same day ? (for me it will be quite impossible to fly every day,or more than 1 patrol in a day ...)

In the rules it says that we must pass 3 hours on 2 seaters before transfering to a fighter unit, Morane L is a 2 seater isn't it ? I hope that the staff members will validate my training hours without passing by martial court copter
