Sadly it's something that a poor FIC fails to address and there's plenty out there.
I would recommend going back to your FIC instructor and askin this question.
Failing that, call Lindsay Brown at Bourn Airfield (RFC Bourn) as I know he is currently sidelined with medical probs so would probably give you some of his free time and he'll have you doing diagram after diagram until you are sick of it - seen many a budding FI doing similar down there!
