Aviation Glossary :: G Load Stability  Aviation Glossary :: G Load Stability FAA Written Test Preparation
Aviation Glossary Welcome to the Dauntless Aviation Glossary!

At Dauntless, our editorial staff maintains the web's largest unified glossary of aviation terms. This glossary is built from a combination of official, quasi-official, and proprietary sources (including original material that we develop oursselves). Uniquely, we often provide multiple definitions of a given term so that you can find that which best applies to you. In order to maximize your learning efficiency, this glossary (and similar ones for our international users) is incresingly fully integrated into our aviation learning apps, including our FAA written test prep and FAA practical test prep software and apps. If you like this glossary, you'll love them with their polished learning environments and world's best and clearest content (please do give them a try.).

G Load Stability
G Load Stability
The tendency of an aircraft to restore any g-load disturbance or variation back to the original 1g loading. Any disturbance, wind or flight path change, will change the g-load of the aircraft – it’s effective weight. G-load stability infers that the attitude of the rotor disk and its resultant lift force will self-adjust to restore the g-load back toward normal 1g. In a gyroplane, g-load stability means that the Rotor Thrust Vector (RTV) is physically located aft of the CG of the aircraft. This is verified in flight testing by increasing the g-load on the aircraft by establishing a steady bank, and verifying that aft stick pressure is required to maintain the original straight and level trimmed airspeed. In the banked and turning flight, the CG located forward of the RTV, causes the nose to pitch lower, requiring aft stick pressure to maintain original airspeed. This is analogous to g-load stability in an airplane that also requires the CG to be forward of the Thrust Vector of the wing. G-load instability would be indicated by the requirement to provide forward stick pressure to maintain original straight and level airspeed while in a banking turn. G-load instability would result in divergent pitch and airspeed resulting from a g-load disturbance – upon reduced g-load in a down gust for instance, the nose of the aircraft would drop, further reducing the g-load on the aircraft and continuing this process to increasing nose-down pitching.
