Which function is described as being provided by the Digital Electronic Control?

• A. An idle control function
• B. A fuel temperature control function
• C. A load sharing function
• D. An exhaust gas recirculation function

Answer: (C)

The Digital Electronic Control provides load sharing. In a two-engine helicopter like the UH-60, the DEC continuously coordinates the two engines so they contribute roughly equal torque to meet the pilot’s demand. It monitors engine outputs and adjusts fuel flow to each engine, maintaining balanced power, preserving symmetrical thrust, and helping keep rotor speed and handling stable during climbs, descents, or maneuvering. This automatic balancing is why load sharing is the function described. Other functions listed—such as idle control, fuel temperature control, or exhaust gas recirculation—are separate engine-management tasks and do not describe the DEC’s role in balancing engine power between engines.
