What is a direct outcome of FADEC scheduling fuel to the nozzles?

• A. Prevents overshooting power changes and over-temperature conditions
• B. Increases engine overshoot risk
• C. Prevents any changes in engine power
• D. Disables engine monitoring systems

Answer: (A)

The direct outcome is preventing overshoot in power changes and keeping turbine temperatures within safe limits. FADEC tightly controls fuel flow to the nozzles based on the commanded power and real-time sensor data (like N1, EGT, pressures), ramping fuel delivery smoothly rather than delivering it instantly. This gradual adjustment helps avoid sudden jumps in engine thrust that could push the engine past safe temperature or pressure limits, so accelerations and decelerations stay within designed margins. In other words, fuel scheduling is about making power changes smooth and within safe operating envelopes, not about stopping any change, not about increasing overshoot, and not about disabling monitoring.
