Just one tip, when you see a grid reference e.i. M13 with an enemy group i.e, 5 Heinkells at 4000M you need to allow for the group to have moved into the next sector on their flightpath by the time you read it on screen. Open your map and navigate to intercept somewhere ahead or behind to pick them up

Make sure your altitude is higher than the enemy group, you will see them much easier and, as you approach, scan for enemy escorts before engaging.
