What does control instruments' calibration allow pilots to do?

Calibration of control instruments is crucial for pilots as it ensures that the instruments provide accurate readings and feedback, which allows them to make precise adjustments. By having well-calibrated instruments, pilots can adjust inputs into the aircraft's systems in defined increments, which is vital for maintaining control, especially in varying flight conditions.

For instance, during climbs, descents, or turns, precise adjustments to the throttle, pitch, and bank angles are necessary to maintain desired flight paths and performance. This accuracy directly impacts the pilot's ability to manage the aircraft effectively. The other options do not relate to the fundamental purpose of instrument calibration; rather, they focus on operational aspects or actions that require instrument accuracy but do not encompass how calibration specifically enhances pilot control through precise input adjustments.
