1) When your observer spots an unidentified or enemy plane it would be most realistic if you got an on screen message like "Observer: enemy aircraft 5 o'clock high!" In life the observer would slap you on the shoulder and point to impart this rather urgent news. I know he will track enemy aircraft with his Mg but you have to look back, often from external view to see it. This is vital stuff which your observer would not keep to himself!!
Great idea..thought about this myself. Think i may have mentioned it aswell somewhere. Just needs to come up the same way as the instructor messages come up. You could even have "pull left\right" etc etc. Do it bold with exclamation marks if urgent!
