Modern aircraft depend on a wide array of systems to perform, many of which are powered by hydraulic or pneumatic mechanisms. While both systems are grounded in the principles of fluid dynamics, they operate in fundamentally different ways; hydraulic systems use incompressible liquids to generate force, whereas pneumatic systems harness compressed gases to produce motion. In this blog, we will examine how each system type is implemented across aircraft platforms, beginning with their distinct operational characteristics before taking a comparative look at which tasks hydraulics and pneumatics are typically chosen to perform.
Learn MoreHydraulic systems are vital in multiple areas of aircraft, responsible for generating the force behind tasks ranging from fine-tuned control surface movements to powering the various tasks required of landing gear assemblies. These systems transmit energy through the circulation of pressurized fluid—typically a specialized, non-compressible oil—delivering consistent and controlled mechanical power.
Learn MoreThe attitude indicator (AI), also known as the artificial horizon, is an important flight instrument found in every aircraft. The AI helps the pilot maintain awareness of the aircraft’s position relative to the Earth’s horizon. It is particularly useful in times of inclement weather or other instrument meteorological conditions - conditions which require pilots to fly primarily or completely by the use of their instruments because of lack of visibility.
