Which medium is utilized along with oil pressure to power aircraft elevators?

• A. Oxygen
• B. Hydrogen
• C. Nitrogen
• D. Argon

Answer: (C)

The medium that is utilized along with oil pressure to power aircraft elevators is nitrogen. Nitrogen is commonly used in hydraulic systems because it is an inert gas that can be compressed, allowing it to serve effectively as a cushion in some hydraulic applications. In aircraft systems, nitrogen is often used in hydraulic accumulators to provide additional pressure support, ensuring that the hydraulic system can maintain consistent performance during operation. Given the context of aircraft systems, nitrogen's properties make it suitable for maintaining efficiency in hydraulic operations, which is critical for controlling surfaces like elevators. The other gases mentioned—oxygen, hydrogen, and argon—do not possess the same inert, non-reactive, and compressible qualities that make nitrogen ideal for this purpose.
