What is the function of the landing gear oleo strut?

• A. Provide hydraulic fluid to wheels
• B. Absorb landing shock and support aircraft weight on ground
• C. Generate electricity
• D. Improve tire grip

Answer: (B)

The landing gear oleo strut is there to absorb the shock of touchdown while supporting the aircraft’s weight on the ground. It combines hydraulic fluid and compressed gas in a cylinder with a piston so that, on landing, the strut compresses and the hydraulic fluid damps the motion while the gas provides a spring force. This cushions the impact, reduces peak loads on the airframe, and helps keep the aircraft stable and level as it taxis. It does not supply fluid to the wheels, generate electricity, or directly improve tire grip.
