SCG trolleys are often equipped with various systems and equipment that supply power, air, or fuel to the aircraft during ground handling or maintenance procedures. For example, an SCG trolley can be used to supply air to the aircraft when the aircraft’s air conditioning system is off or to provide electrical power to run the aircraft's systems.

The 2-170-700-21 (Triumph PN EMC-100) is a sophisticated, low cost, dual channel engine control in a single housing. The unit consists of two dissimilar, mechanically separated channels operating independently, but cooperating with each other. The software is organized in a multi-partition architecture which includes COTS real-time operating and application specific control system software. Most of the software has been developed to RTCA/DO-178B Level A (flight critical standard), but the software architecture permits partitions which perform non-critical functions to be developed to lower levels, thereby reducing life-cycle costs.

The key competence of the HELZEL team is the expertise in HF techniques, in particular in over-the-horizon radar technology. This includes the required signal processing hardware and software. The HELZEL high-frequency over-the-horizon radar OTHR uses fast and accurate software beam-forming utilising an automatic self-calibration technique. The low-noise, non-interrupted FMCW operation mode provides the best range / power performance on the OTHR market. This allows operation with quite low power levels (1 kW) to get a range of up to 200 Nautical Miles
