🔍 Key Concepts

• Controllable pitch propeller (CPP) hydraulic oil system – why oil pressure and temperature matter for safe operation • Required alarms vs. instrumentation – what conditions must trigger an alarm on a propulsion system • Difference between an indicator (display) and a protective alarm

💭 Think About

• Ask yourself: which of these options is simply information for the operator, and which conditions could immediately threaten loss of thrust or serious machinery damage if not alarmed? • Think about how a CPP actually changes blade angle: which parameter must be kept within a safe range by an automatic alarm, and which parameter is already continuously shown to the operator? • For oil systems that control pitch, which situation is clearly dangerous if it goes too low or too high, and would almost certainly have to raise an alarm under machinery‑space safety standards?

✅ Before You Answer

• Identify which choice is a position indication (shows current pitch) rather than a condition of the oil system. • For each oil‑related option, consider: would abnormal pressure or temperature directly affect the ability to control propeller pitch and thus require an alarm? • Before choosing, separate in your mind: (1) what must be alarmed for protection vs. (2) what is simply displayed for monitoring.
