EASA PPL subject 081 — aerodynamics & control
Principles of Flight (081) covers the four forces acting on an aircraft: lift, weight, thrust and drag. You learn how the aerofoil generates lift, when a stall occurs and how the control surfaces work together.
Topics covered
Draw the force diagram for climb, descent and level flight.
Stall is the most tested topic: know all factors that affect stall speed.
Connect principles of flight to the cockpit: when do you use trim, and why?
Use flight simulator videos to visualise different flight attitudes.
