Module 11 — Aeroplane Aerodynamics, Structures and Systems

11.11(a) — System Description

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.

Locked Inside this note

Hydraulic systems provide the force to operate flight controls, landing gear, brakes, nose wheel steering, thrust reversers, flaps, slats, spoilers, and cargo doors. Transport aircraft typically have three independent hydraulic systems for redundancy, operating at 3,000 psi (newer aircraft: 5,000 psi for weight savings).
