The Hidden Power Behind Efficient Ground Operations

More Than an External Power Source

An aircraft is on the ground, critical onboard systems must continue to operate reliably. Avionics, lighting, communication equipment, and maintenance procedures all depend on a stable power supply. This is where modern Ground Power Units (GPUs) play a vital role. Often overlooked as part of airport infrastructure, these systems have a significant impact on operational efficiency, aircraft availability, and overall operating costs.

ELME Elektromechanik develops Ground Power Units for a wide range of applications, from compact mobile units for light aircraft to high-performance 28 V DC and 400 Hz AC systems for business aviation, MRO facilities, airports, and military operations. The company's portfolio includes mobile, stationary, and vehicle-mounted solutions, ensuring reliable power for virtually every ground handling scenario.

More Than an External Power Source

A Ground Power Unit does much more than simply provide electricity. Delivering a clean and stable power supply protects sensitive onboard electronics, supports maintenance activities, and enables safe operation during extended ground time. Whether technicians are performing avionics inspections, software updates, or routine servicing, dependable external power minimizes the risk of voltage fluctuations and system interruptions.

Reducing Aircraft Wear and Operating Costs

Many operators still rely on the aircraft's Auxiliary Power Unit (APU) to supply electrical power while parked. Modern Ground Power Units offer a cost-effective alternative. By providing external electrical power, they significantly reduce APU operating hours, helping operators lower fuel consumption while minimizing wear on one of the aircraft's most maintenance-intensive systems. Over hundreds of turnarounds, this translates into substantial savings in both maintenance and operating costs.

Scalable Solutions for Every Operation

Every operation has different power requirements. Flight schools and smaller maintenance organizations often require compact 28 V DC units, while larger aircraft demand powerful 400 Hz systems capable of supporting complex onboard equipment. ELME Elektromechanik offers scalable solutions ranging from portable power cases to high-capacity systems designed to deliver continuous high-current output and reliable peak performance under demanding operating conditions.

Engineered for Everyday Reliability

Ground support equipment must perform consistently in challenging environments, from extreme temperatures to continuous daily operation on busy aprons. Reliability, durability, and ease of use are therefore central to the design philosophy behind ELME Elektromechanik's Ground Power Units. Developed and manufactured in Germany, these systems are built to withstand demanding operational conditions while providing long service life and dependable performance.

Whether in a maintenance hangar, on the apron, or during fast aircraft turnarounds, Ground Power Units have become an essential component of modern aviation infrastructure. By ensuring reliable electrical power whenever an aircraft is on the ground, they help keep maintenance, servicing, and flight operations running smoothly and efficiently.
