Now I'm not much of a mathematician......I was fine until the alphabet decided to get involved....but after being instructed by ATC to turn left to 370 degrees I must admit I was stuck.
Was constantly nagged to continue turn to 370 degrees after ignoring them and flying my own approach to Heathrow. If I had had the room and time I might have tried turning to 010 to see if that satisfied them but didn't think till too late. I love it when someone else messes up. Makes me feel so much better.
Logs attached. Kindest regards Steve.
