Aero Fact: V-n Diagram Basics

Flight envelope defined by load factor vs airspeed; maneuvering speed marks stall/intersection boundary.

Definition: Operating limits shown on axes of load factor and airspeed.

Physics insight: Stall boundaries and structural limits (n_max, n_min) define intersections.

Example: At VA, full deflection is stall-limited; above it, structural risk rises.

V_A = V_S √n_limit

Rules of thumb: Know turbulence penetration speed and VA; both vary with weight.

Common pitfalls: Assuming VA is constant; ignoring weight dependence.
