Name two basic propulsion system parameters a pilot monitors during operations.

• A. Fuel flow and EGT
• B. RPM and Oil pressure
• C. Altitude and airspeed
• D. Cabin pressure and APU load

Answer: (A)

Monitoring fuel flow and EGT provides a direct read on how the engine is burning fuel and producing thrust. Fuel flow shows how much fuel is being delivered to the engine, which helps you manage power settings and detect issues in fuel delivery or consumption. EGT, the exhaust gas temperature, indicates combustion efficiency and potential overheating; it rises with more fuel being burned and should stay within certified limits to avoid damage. Together, these two parameters give a clear, immediate view of propulsion performance across operating conditions.

While RPM and oil pressure are important indicators of engine health, they don’t convey the combustion and fuel management status as clearly as fuel flow and EGT. The other options relate to non-propulsion aspects of flight.
