If you’ve ever flown on a plane, you’ll know that the entire industry is a carefully constructed balance of managing costs and providing planes with enough support and resources to ensure they can fly and run properly. A core component of this is the power unit, a tool that has quickly become synonymous with the airplane industry because of how often it’s used and how important it is to the entire process.
- Uses
The ground power unit is an integral part of the aviation industry for a simple reason: it provides electricity to an aircraft at the most vital parts of the flight experience, namely the liftoff and after landing. Planes get their electricity from the engine and plane battery during the flight. Still, these are two massive pieces of equipment and need time to start before they’re ready to provide power. During that time, GPUs ensure that pilots, engineers, and passengers can enjoy the convenience of having air conditioning and other systems while system checks are performed. Systems checks are a vital part of the pre-flight process, too, as pilots check the plane’s avionics and control systems before starting the flight, and none of this would be possible without the energy supplied on the ground using these units.
- Types of GPUs
There are many types of GPUs, but the most important types are mobile GPUs and fixed ones, each with different applications. Fixed GPUs are perhaps the most important for major companies and businesses, as they’re installed in dedicated parking spots for planes before liftoff, adding an extra layer of convenience when passengers are boarding and when routine maintenance has to be performed. However, airports are home to a lot more planes than just commercial jets, from smaller cargo planes to private jets, and these often use mobile GPUs that are attached to small vehicles that can shuttle them anywhere in the airport, allowing greater flexibility in day-to-day operations.
- Components
GPUs are made using a lot of different components, but the most important ones are diesel engines, a generator, control panels, and a lot of cables that connect to the input receptacles on a plane. As the industry tries to rely less and less on fossil fuels, many GPUs are beginning to offer purely battery-driven power outputs, but every other part of the unit remains the same. Engineers are able to connect the cables of the unit to the plane easily while ensuring they’re always in control of how much power is being supplied using the control panels, whether it’s shifting the output voltage or cutting off power entirely once the plane battery kicks in.
- Benefits of using GPUs
The biggest benefits of GPUs are that they speed up operations and flights during an average business day in an airport, allowing flights to happen routinely and faster than they would’ve otherwise. As previously mentioned, airplane batteries and auxiliary power units take some time to start, and it’s only after they’re powered on that planes can take advantage of their output. GPUs ensure that passenger boarding and systems checking can occur, while this process takes dozens of hours off of flight time each week.
- How relied-upon GPUs are
Since GPUs are so inherently tied to the energy needs of planes, especially in the initial stages of the flight, airports all over the world are totally reliant on them, installing several of them at vital gates where planes are stationed, in hangars where maintenance takes place, on vehicles to supply mobile power and more. This is why so much research and development is being poured into developing and improving GPUs by integrating renewable energy and even more types with countless potential applications, all hoping that airport procedures will become even faster and more efficient.
Conclusion
Planes are behemoths that need far more attention than you’d think, including regular maintenance, check-ups, and, most importantly, ground support. Machines that provide this support, including GPUs, are so important because they help in every step of the flight, from providing enough electricity to power the pre-liftoff passenger experience to allowing pilots to check how their plane is performing so that there aren’t any issues during the flight.
