Why is monitoring engine parameters crucial during operation?

Monitoring engine parameters is vital for ensuring safe operation and detecting any abnormalities that may arise during engine performance. Continuous evaluation of various engine metrics, such as temperature, pressure, RPM, and fuel flow, allows operators to identify trends and anomalies that could indicate a malfunction or potential failure.

By keeping a close eye on these parameters, operators can make informed decisions to maintain safety, prevent accidents, and address issues before they escalate into more serious problems. For instance, a sudden increase in temperature could signal an impending failure, allowing for corrective actions to be taken in time, such as reducing power or diverting the aircraft.

While other considerations such as profitability, historical performance, and adjustments to flight plans are relevant to overall operation and management, the primary focus of monitoring engine parameters is on the operational safety and reliability of the engine itself. Ensuring that the engine is functioning correctly is paramount, as it directly impacts the safety of the flight and the well-being of passengers and crew. This makes it the most critical reason for monitoring during operation.
