Which of the following is listed as a component of the UH-60S engine control system?

• A. PCLs
• B. Pitot Tube
• C. Altimeter
• D. Radar Altimeter

Answer: (A)

Power Control Levers are the pilots’ interface to engine power, and they are a direct component of the engine control system. In the UH-60S, each engine’s power is commanded through its PCL, which the FADEC reads to regulate fuel flow and turbine speed to achieve the desired power setting while staying within safety limits. This is the mechanism that actually controls how the engine responds to pilot input.

The other items belong to different systems: a pitot tube is part of the air data system that measures dynamic pressure to determine airspeed, while an altimeter and a radar altimeter measure altitude for flight guidance and avoidance of obstacles. They don’t control engine output, which is why they aren’t considered components of the engine control system.
