I can't speak for the BTEC but the degree course of same subject generally only covers the cockpit so far as control geometry's impact upon flight mechanics.
I interviewed half a dozen Aero-Eng graduates for a job a few years ago and took along with me a blown up cockpit photo. Each of them I put a copy in front of them and asked them to point out the main controls and explain what they did - most of them couldn't manage.
