About this Exam
Prepare with the Utility Helicopter 60 Black Hawk (UH-60S) Academics Exam 2 Practice practice quiz. This question bank includes 10 questions covering engine, description, correctly, utility, and helicopter. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.
Sample Questions
Question
1
Which description correctly describes the Digital Electronic Control (DEC) in this system?
Explanation:
The Digital Electronic Control is the solid‑state engine control unit that governs how the engine runs by processing sensor data and commanding the fuel system and other actuators. It’s placed beneath the compressor casing so it can monitor engine parameters directly and stay within easy reach of cooling air. It’s powered from the aircraft’s electrical system—either the alternator or AC power—so it remains powered as the engine shifts its electrical load. Cooling comes from airflow through the scroll case, which carries heat away from the DEC while the engine is operating. This setup reflects its role as an electronic controller rather than a hydraulic device, a cockpit switch, or a thermal insulation component.
Question
2
For missions longer than 6 hours, where should the engine oil level be?
Explanation:
On long missions the engine oil heats up for an extended time, causing the oil to expand and some amount to be consumed. You want a level that can accommodate that expansion without risking overfill, while still providing enough reserve oil for continued lubrication if some oil is consumed during the flight. Keeping the oil at mid-level gives that buffer: it’s not so full that hot oil would push it into an overfull/foaming condition, and not so low that expansion or consumption would lead to oil starvation. So mid-level is the safest, most practical target for missions longer than six hours.
Question
3
The NP parameter is described as which?
Explanation:
Rotor speed is kept constant by the helicopter’s governor. NP refers to the main rotor speed, and in normal flight the governor adjusts fuel flow to hold NP at a set value. This stable rotor speed ensures predictable blade pitch and lift, making flight control smooth and safe. The throttle or collective changes primarily affect Ng (gas generator speed), not NP, because the system is designed to keep the rotor speed steady while the engine’s gas generator varies to meet power demands. So NP is described as constant because the rotor speed is actively regulated to stay at the commanded setting, rather than continually rising or falling during standard operation.
Question
4
Which of the following is NOT a Hot Section Module Component?
Explanation:
Hot section modules are the parts that directly handle the hottest gases produced in the engine, meaning components that live in the combustion and turbine flow path. The combustion liner is the inner wall of the combustor where fuel burns, and the stage 1 nozzle is part of the hot gas path that shapes and directs those hot gases into the turbine. The gas generator stator consists of fixed vanes in the gas generator section that guide the high-temperature flow and withstand extreme temperatures. The exhaust frame, on the other hand, sits in the exhaust/structural area downstream of the turbines and serves as a support/attachment structure rather than a component that participates in the hot gas path. So it is not considered a hot section module component.
Question
5
How is a leak in the 1st stage primary servos isolated?
Explanation:
The test is about quickly isolating a hydraulic leak by targeting the affected stage. In the UH-60, the SERVO OFF switch is used to shut off hydraulic flow to a specific servo stage. Setting it to the 1st stage removes hydraulic pressure from the first-stage primary servos, effectively isolating that stage from the rest of the system. This contains the leak, reduces fluid loss, and prevents contamination from spreading, while preserving the other hydraulic circuits for continued control. Other actions aren’t appropriate for this situation: turning off the master battery cuts power to the entire helicopter, pulling a tail rotor circuit breaker doesn’t isolate the first-stage servos, and closing a bleed valve isn’t a reliable way to stop a leak or isolate the affected circuit.
