Which of the following is NOT a power setting category?

• A. Power-On Cautionary
• B. Power-Off Transient
• C. Power-On Sustained
• D. Power-Off Minimum

Answer: (C)

The category labeled "Power-On Sustained" is not a recognized power setting category in the context of aircraft performance and operation. Instead, the established categories typically include distinctions focused on power settings for both power-on and power-off conditions, which are crucial in understanding aircraft handling and performance limits.

The categories serve to categorize how the aircraft behaves under specific power conditions—whether it is operating under stable power or experiencing transient variations. In contrast, options like "Power-On Cautionary" and "Power-Off Minimum" accurately reflect recognized categories for managing power settings during flight operations, where caution and minimum thresholds are essential for safety and performance monitoring.

Understanding the appropriate voltage and power settings for both power-on and power-off operations ensures optimal performance and safety during all phases of flight, and recognizing the incorrect category helps reinforce the structured framework of power management in aviation.
