I think it was late 80's when I played an airplane game where you had a biplane and had to accomplish some different scenarios e.g. shooting motorcycles and refuel with a zeppelin.
You chose the task by flying to it on a map and the action happened as a 2D-sidescroller with a possible additional split view from above.
I've tried to search for this game every now and then for years but haven't come up with anything. Maybe some smart gamer knows the game I'm talking about.
