Planes are seen as reliable modes of transport for a reason—they’re often the safest and most tightly engineered machines in the world, capable of flying hundreds of passengers at a time completely safely. The countless different machines and systems involved in running the plane, however, all need hydraulic fluid to run at their best, which is why aircraft managers make sure they’re only ever getting the best hydraulic fluid available on the market.
1- Fire resistance
Skydrol is one of the most popular brands of hydraulic fluid in the world for one particular reason: it’s incredibly safe and reliable in emergency situations. Planes have a lot of moving parts and heavy engines that generate a lot of heat, and if something goes wrong, a minor issue would likely result in a fire breaking out. The great thing about this hydraulic fluid is its high flash point, which means it’s not flammable, ensuring that any fire that breaks out remains contained and can easily be dealt with by the flight on board. If the hydraulic fluid in use didn’t have this characteristic, fires could spread much faster through the rest of the plane, which could result in irreparable damage.
2- Thermal stability
As previously mentioned, planes are massive, with engines big enough to transport hundreds of passengers at a time, and all of this activity leads to a ton of heat generation. Even if there isn’t a fault, this heat does lead to some minor difficulties from time to time, as lesser hydraulic fluids could get damaged and perform poorly if there is enough heat in the vicinity. This brand, on the other hand, is far more stable, so plane managers are able to send their planes on flights with a clear mind because they know the hydraulic fluid in the plane will be good to go no matter how hot the internals get.
3- Corrosion protection
Corrosion is another important thing to consider in planes since planes cost millions of dollars and are only able to pay off that initial investment if they’re able to fly for years, if not decades, continuously. This long-term use could lead to corrosion over time, especially if they’re docked in coastal climates, but this is another area where the best hydraulic fluid can prevent damage since it protects against corrosion and rust and, since the hydraulic fluid is coated over the most important parts of the plane, they’ll rust less, leading to a longer lifespan for each part, or maybe even for the plane as a whole.
4- Long-term use
The long-term use of any hydraulic fluid is important because planes are not constantly docked for repairs or to be topped off. The best brands in the world can be used for several flights in a row without needing to be changed, giving the best performance possible without anything breaking down or any operational issues. On the other hand, if you get your hands on some hydraulic fluid that costs less but doesn’t last as long, you’ll find yourself having to replace it far more often, and, as a result, you may even have to spend more money than you planned.
5- Environmental resistance
As previously mentioned, rust and corrosion prevention is a crucial characteristic of this brand of hydraulic fluid. There are more contaminants in the air besides just humidity, though, including dirt and dust from the flight, which can get into the internal parts of the plane, getting into some of the most crucial things needed for a flight and, over time, cause a plane to be far less efficient. However, hydraulic fluid that coasts these parts will keep out all of the dirt that piles up after each flight, resulting in you needing to repair your plane far less often.
Conclusion
Hydraulic fluid is a central tool in the management and functioning of planes since it is the primary thing that ensures pilots are in control of the wings, rudders, landing gear, and everything in between. Hydraulic fluid needs to be incredibly safe, last a long time, and be easy to replace; few fluids on the market have all of these characteristics, but if you use the information in this article, you’ll be able to find the one that transforms your plane and its flying capabilities.
