You're planning a flight. What's the most reliable ground power unit for your aircraft?

When planning a flight, the most reliable ground power unit for an aircraft is typically a diesel-driven generator or a solid-state ground power unit. These units provide consistent and stable power to the aircraft's systems during ground operations, ensuring reliability and safety. Additionally, it's important to consider factors such as compatibility with the aircraft's power requirements, ease of use, and availability of maintenance support when selecting a ground power unit.

Ground Power Units (GPUs) for aircraft come in various types, including Mobile (mounted on vehicles), Fixed (permanently installed), Diesel-powered, Electric-powered, Hybrid (combining features), and Frequency Converters for adjusting electrical frequency. Selection depends on factors like airport infrastructure and environmental considerations.

Choosing a GPU for aircraft, consider factors such as: Type: Decide between mobile or fixed units based on your airport's needs and flexibility requirements. Power Source:Choose between diesel or electric GPUs, considering factors like efficiency and environmental impact. Capacity:Ensure the GPU can provide sufficient power for the aircraft fleet, considering both current and potential future needs. Technology:Opt for reliable brands with advanced features that align with industry standards. Maintenance: Regular upkeep is crucial for reliability, so choose a GPU with accessible maintenance and service options. Compatibility:Ensure the GPU meets the electrical requirements of the aircraft it will support, including voltage and frequency.

To use a Ground Power Unit (GPU) for aircraft: Connectivity: Ensure the GPU is compatible with the aircraft's electrical requirements and connect it to the aircraft's power receptacle. Power On:Activate the GPU by following the manufacturer's guidelines. This may involve starting the engine (for diesel GPUs) or switching on the power supply (for electric GPUs). Monitor:Keep an eye on the GPU's status indicators to ensure it is providing a stable power supply to the aircraft. Disconnect:When aircraft systems are adequately powered or when the aircraft is ready to start its engines, disconnect the GPU safely. Shutdown: Follow the proper shutdown procedure for the GPU to avoid unnecessary wear and tear.

Ground Power Units (GPUs) for aircraft vary in design and reliability. Many airports use diesel or electric GPUs, and reliability depends on factors like maintenance, build quality, and technology. Brands like ITW GSE, Hobart, and JBT AeroTech are known for producing reliable GPUs. Choosing the most suitable unit depends on specific airport requirements and the type of aircraft it will support. Regular maintenance and adherence to industry standards contribute to the overall reliability of ground power units.

Modern airports now offer GPUs integrated into their air bridge systems which are using the main power source of the airport to supply the required power levels to different aircraft by having a control system and circuitry. They have so many advantages such as being quiet, having different output selections, less risk of tripping under high load demands and also being connected to the airport emergency power source so that they ensure the required electrical power is always supplied to the aircraft. Apart from that, and in smaller airports, GHAs shall select the units which are reliable and having the required output levels for the types of aircraft flying to those airports, as modern aircraft are quite sensitive to power trips and surges
