General Authority of Civil Aviation (GACA) Aeronautical Information Publication (AIP) Practice Exam

What should be checked during an engine run-up to minimize ice buildup?

1. Area behind the airplane is clear

2. All passengers are seated

3. Engine oil is at normal level

4. Fuel tanks are full

The correct answer is: Area behind the airplane is clear

During an engine run-up, checking that the area behind the airplane is clear is crucial for safety and minimizing the risk of ice buildup. This procedure is part of ensuring that the aircraft is being operated safely and effectively, particularly in conditions where ice might form or affect performance. When the engine is run at high RPMs, it can stress components and create conditions that may lead to ice forming in certain areas of the aircraft, especially if moisture is present in the atmosphere. Additionally, ensuring that the area is clear helps prevent any foreign object damage (FOD) or injury to personnel nearby. While other checks like seating of passengers, engine oil levels, and fuel tank status are important for overall flight safety and operational readiness, they do not directly relate to minimizing ice buildup during an engine run-up. Ensuring the area is clear allows the pilot to conduct the run-up safely, which indirectly supports optimal engine performance and reduces the risk of ice-related issues.
