Which statement is NOT a listed function of a shock strut?

• A. Absorbs shock of landing
• B. Dampen movements
• C. Stores hydraulic fluid
• D. Connects bogie to aircraft structure

Answer: (C)

The main idea here is how a shock strut (oleo strut) functions in supporting and shaping the landing and ground-handling experience. It is designed to absorb the impact of landing by compressing under load, using a combination of gas and oil to cushion the strike. The oil flow through restricted paths provides damping, converting some of that kinetic energy into heat to prevent a felt jolt. The strut also serves as the mounting link that connects the bogie (the wheel assembly) to the aircraft structure, helping to carry the aircraft’s weight and keep the wheel aligned during operations on the ground.

Storing hydraulic fluid isn’t a listed function because, while the damping action relies on hydraulic oil inside the strut, the strut itself isn’t a reservoir for hydraulic fluid. The hydraulic fluid is part of the broader hydraulic system of the aircraft, with reservoirs outside the strut. So the statement about storing hydraulic fluid is not a function of the shock strut.
