Module 12 — Helicopter Aerodynamics, Structures and Systems

12.5(a) — Airframe Structures — General Concepts

Practice questions test what you know. This note teaches what you don’t.

Question banks train recall. The questions that decide a pass are the borderline ones, where two answers look right — and those are won by understanding. That is what this note is written for.
