Aerodynamics & Systems: Commercial Pilot Airplane Knowledge Test (CAX) topic guide

Aerodynamics & Systems carries 16% of the Commercial Pilot Airplane Knowledge Test (CAX) blueprint used in this course, the third-largest of its 6 weighted areas. It spans 14 concepts. The course teaches it in 3 study units: Load Factor & Stall Speed, Stalls & Spins and Complex Aircraft Systems.

  • How does load factor affect stall speed, and what is the formula? — FAA-H-8083-25 Ch. 4 (Aerodynamics of Flight)
  • What does the Vg (V-n) diagram show, and what are its structural limits? — FAA-H-8083-25 Ch. 4 (Aerodynamics of Flight)
  • Why does maneuvering speed (Va) DECREASE as aircraft weight decreases? — FAA-H-8083-25 Ch. 4
  • What is an accelerated stall, and when is it most likely to occur? — FAA-H-8083-25 Ch. 4
  • What is the fundamental aerodynamic definition of a stall, and what factor determines stal — FAA-H-8083-25 Ch. 4
  • What is a spin, how does it develop from a stall, and what is the PARE recovery sequence? — FAA-H-8083-3 Ch. 4
