When I was at flight school many moons ago, I was a cadet "tagged" to a fixed wing course. The fixed-wing cadets (we'll call them planks) studied "Principles of Flight Fixed-Wing" as it was a know science. For the bold, courageous, handsome rotary-wing cadets (all 2 of us), it was called "Theory of Flight Helicopters" as some of it was still an unknown science and still a theory.
To answer your question, not a clue mate, it was a long time ago. Good luck with the flying
