In aircraft systems, flexible hoses are classified by what dimension?

Flexible hoses used in aircraft systems are classified primarily by their inside diameter. This measurement is crucial because it determines the flow capacity of the hose, ensuring that the system can deliver the proper volume of fluids or gases under various operating conditions. Knowing the inside diameter is essential for compatibility with fittings and other hardware, as it affects pressure drops and the overall performance of the system.

The inside diameter allows engineers and technicians to select the correct size hose for specific applications, ensuring efficient operation and minimal risk of leaks or blockages. Additionally, aircraft systems often require precise flow rates, making the inside diameter a critical factor in maintaining system integrity and performance. Understanding this aspect of flexible hoses plays an important role in aircraft design and maintenance practices.
