What action should you take if full power vibration limits are exceeded on a gas turbine engine?

🔍 Key Concepts

• Manufacturer’s operating limits for vibration on gas turbine engines • Difference between immediate control actions vs maintenance procedures • Purpose of vibration monitoring on high‑speed rotating machinery

💭 Think About

• When an instrument shows a limit being exceeded, what is the first priority: protect the machinery now, or plan maintenance later? • Which of these choices can be done instantly by the watch stander from the control station, and which require the engine to be shut down and cooled for maintenance? • Think about why vibration limits exist on gas turbines—what kind of short‑term action best prevents further damage or failure?

✅ Before You Answer

• Identify which options are operational adjustments versus scheduled maintenance actions • Ask: On an exam, when a limit is exceeded, do you normally take immediate corrective control action or schedule a future inspection? • Eliminate any option that implies doing nothing when a protective limit alarm is exceeded
