What power setting should be used for a section takeoff?

• A. 80%
• B. 85%
• C. 90%
• D. 95%

Answer: (C)

For a section takeoff, using a power setting of 90% is optimal as it provides a balance between thrust and engine performance necessary for a safe and efficient ascent. At this setting, the aircraft can achieve the required climb rate while maintaining adequate margins for engine reliability and fuel efficiency. Setting the power at 90% allows for controlled performance in various conditions without overtaxing the engine, which could lead to potential overheating or mechanical issues. This level ensures that the aircraft can better handle the aerodynamic load during takeoff while still allowing for response to necessary adjustments during the climb phase. Choosing a power setting that is significantly lower, such as 80%, may not provide enough thrust for aggressive climbs or may lengthen the time taken to reach the desired altitude. Conversely, settings above 90%, such as 95%, may increase stress on the engine, potentially reducing its longevity and efficiency over time, particularly during prolonged operations. Thus, 90% is seen as the ideal compromise for performance and safety during a section takeoff.
