If it takes more than 22.5 minutes to complete your missions, you'll be penalized an increasing amount as the time lengthens. Be aware that the clock starts as soon as the cockpit screen comes up, so don't waste a lot of time looking at the map. You should have your attack plan set beforehand by looking at the map during the briefing.
With this type of scoring, you're rewarded for taking risks and using the realistic modes of the simulation. Since other important parts of the game, such as rank and medals, are based mainly on your score, it's to your benefit to understand how this system works.
