During which range should torque be stabilized on the ground?

The correct range for stabilizing torque on the ground is 62% to 80%. This range is critical for ensuring the engine operates efficiently and reliably during ground operations. Stabilizing torque in this specific range allows for optimal engine performance, preventing excessive wear and tear on engine components while also ensuring sufficient power is available for ground maneuvers.

When the torque is stabilized within this range, the engine operates smoothly, which is vital for pre-flight checks and engine run-ups. Maintaining torque within these limits also helps in achieving the necessary power output without straining the engine, thus enhancing its longevity and performance during subsequent flight operations.
