Why Do Aircraft Need PCA Hoses?

There’s an element of maintenance that aircraft require that other vehicles don’t need. In order to maintain cabin air temperature and quality, PCA hoses are hooked up to the aircraft once on the ground. Other modes of transportation such as buses don’t often experience extreme temperature and humidity changes that long distance air travel does. PCA hoses help keep the aircraft full of comfortable air that’s safe for passengers, pilots and equipment.

Different Options Available

Having PCA hoses attached to aircraft while on the ground saves a lot of money on aircraft damage caused by condensation and unsafe temperatures. Different types of aircraft are likely to encounter different environmental conditions that affect the plane, which makes it important to know which PCA hoses will work best to keep the air quality consistent. The different types of hose include vented hoses which prevent condensation from getting inside the cabin and wearing out equipment, lay flat hoses that are folded flat to allow for easier storage and use, and rigid duct hoses divided into flexible sections that avoid damaging wear and tear.

A Necessity for Aircraft

Unlike other vehicles, aircraft cabins are more airtight to resist the change in pressure and other elements that can affect equipment in the cockpit . PCA hoses allow expensive and sensitive equipment to remain at a constant temperature at all times for the ground support crews. If it wasn’t for PCA hoses, planes would cost much more to maintain because of possible damages to the elaborate system of electronic instrument panels and other parts that most vehicles don’t possess. Preserving equipment conditions wouldn’t be as easy without the use of various PCA hoses available, which is why they have become a crucial part of overall aircraft maintenance measures.
