Ground Power Units (GPU) are essential parts of equipment in the aviation industry. They serve as a primary power source for aircraft parked at the gate or on the tarmac. Ensuring that GPUs are certified is of primary importance since it guarantees the aircraft’s reliability, safety, and compatibility.

In the following article, we will talk about GPU certification, including its significance, the calibration and servicing process to be followed after installation, as well as its maintenance.

Servicing Ground Power Units

Operating or maintaining GPUs requires specially trained staff. For this reason, many airports and airlines rely on dedicated teams of professionals to service their ground power units.

These teams conduct inspections, fault-finding, and repairs on the GPUs to make sure they continue delivering peak performance. During the servicing stage, technicians closely check all aspects of the GPUs. If there is any sign of wear or damage to a part, they will replace the entire unit right away.

They also perform routine maintenance work such as cleaning and lubrication, as well as replacing parts when needed. Additionally, technicians conduct thorough tests and functional checks to ensure that all safety limits are met during the operation of a GPU.

GPU Certification Process

A GPU must pass comprehensive tests before it can be labeled as a certified aircraft, and the GPU certification process follows a number of steps to ensure it meets the standards of the industry and the manufacturer.

Ground power unit certification tests will cover factors such as whether the GPU is safe and reliable, the performance of the unit, toughness in withstanding crashes under heavy seat loads, voltage regulation, lithium-ion batteries, and monitoring the unit’s ability to handle different climatic conditions, just to name a few facets of it.

What’s more, the ground power unit certification process also requires that the GPU specifications be documented in full, including the power it outputs, which aircraft are compatible, and whether it meets safety codes. This documentation carries particular importance since airlines, airports, and regulatory authorities depend on it to check whether a GPU can meet their specific requirements.

Ground Power Unit Calibration Process

Calibration is a vital aspect of GPU certification, and it’s something that any aircraft owner should have in mind. It involves aligning and adjusting the sensors, controls, and measuring devices to ensure that the GPU is accurate and reliable. Calibration is crucial, as it also helps maintain the performance of the GPU and ensures that it provides accurate readings and power output.

The calibration process usually involves special equipment and tools to compare the measurements made by the GPU with known standards. Technicians make changes to the internal settings of the GPU, such as voltage protection, frequency, and power factor, to bring it in line with desired values. Regular calibration extends the life of the GPU, increases its efficiency, and minimizes electrical system accidents and failures.

GPU Maintenance Service

Maintenance is an ongoing process that plays a vital role in the longevity and reliability of GPUs. Regular maintenance covers such tasks as routine cleaning, inspection, and overhauling; periodically replacing parts; as well as updating the software and firmware used by modern GPUs to maintain high-performance levels.

GPU maintenance also involves following the preventative maintenance schedules set out in the service contract, which may call for planned shutdowns lasting several days at a time to allow comprehensive inspections and system tests.

In addition, teams recording all activities of maintenance in great detail provide important information for evaluating the operation of the GPU, any recurring problems it may have, and future work plan tasks required to meet the system’s needs.

The Crucial Role of GPU Certification, Calibration, and Maintenance

In the aviation industry, it’s utterly necessary to certify the ground power units used for aircraft operation. By following strict standards and guidelines, ground power units that have been certified can provide the power needed to start diesel engines, operate various electrical systems, and keep onboard equipment running smoothly.

Through rigorous testing and evaluation, manufacturers and regulatory agencies together ensure that these units meet the highest standards for quality and performance, thus adding to the overall safety and efficiency of handling airplanes.
