What are SPEEDBRAKES/FLIGHT CONTROL SPOILERS?! Explained by CAPTAIN JOE
Captain Joe・2 minutes read
Flight control spoilers, ailerons, inboard ailerons, speed brakes, and ground spoilers play vital roles in controlling and maneuvering aircraft, ensuring safety, stability, and efficiency during various flight phases. These components work together to counteract adverse yaw moments, create drag, decrease lift, and maximize braking efficiency, ultimately contributing to a safe and controlled landing and flight experience.
Insights
- In high-speed flight, ailerons can induce stress on the wings, mitigated by inboard ailerons on planes with expansive wing spans.
- Flight control spoilers serve various functions, including enhancing roll authority, countering adverse yaw moments during turns, and maximizing wheel brake efficiency during landing.

Recent questions
What are the functions of flight control spoilers?
Flight control spoilers serve to enhance roll authority and response during landing and flight, among other purposes.
How do ailerons operate on jet airliners?
Ailerons on jet airliners are operated hydraulically, with redundant hydraulic systems for safety in case of failure.
What is the purpose of inboard ailerons on planes with large wing spans?
Inboard ailerons on planes with large wing spans counteract stress on the wing during high-speed flight, preventing twisting and bending moments.
How do flight control spoilers counteract adverse yaw moments during turns?
Flight control spoilers increase drag on the downgoing wing, reducing yawing and enhancing rolling moments to counteract adverse yaw moments during turns.
Why are ground spoilers extended during landing on aircraft?
Ground spoilers are extended during landing to maximize wheel brake efficiency, dump lift, press the aircraft weight onto the landing gear, and create aerodynamic drag for a safe landing.
