Feeling a lot better now....cough all but gone and cold symptoms pretty much gone too. Still at home until Friday so, knowing some things could do with sorting, I tidied up/updated my flying paperwork and thought....hmmm....I have a table with figures on it for calculating the Wind Angle for level bombing....what about a hand held calculator!
I printed off a basic compass and the wind angle dial found in the IL2 bombsight and found a filing clip used for keeping paperwork together. The compass is to show the aircraft heading and wind direction, the wind angle dial for the aircraft heading and the clip is for the wind direction.
Enter the aircraft heading onto the compass using the aircraft, place the wind direction pointer on it's heading and there is the offset angle...in this case 50 degrees to starboard.
Works a treat
