Aerospace Dimensions Module 2 Practice Exam

What is the primary way feedback control contributes to attitude stabilization?

It relies on manual pilot input only. It uses sensor data to adjust actuators, reducing deviations and maintaining the desired orientation. It ignores sensor data to simplify control. It increases attitude deviations to test responsiveness.

Correct Answer:

It uses sensor data to adjust actuators, reducing deviations and maintaining the desired orientation.

Explanation:

Feedback control stabilizes attitude by closing the loop between measurement and action. Sensors continuously measure the vehicle’s current orientation, a controller computes the error between where you want to be and where you are, and actuators are commanded to reduce that error. This automatic correction keeps the attitude steady and brings it back after disturbances, maintaining the desired orientation. Manual input can influence attitude, but the primary stabilizing mechanism is the sensor-driven, automatic adjustments that continuously correct deviations. Ignoring sensor data or deliberately increasing deviations would remove or defeat this corrective loop.
