What three aspects does the AHRS primarily control?

The correct answer focuses on the primary functions of the Attitude and Heading Reference System (AHRS), which are fundamental to an aircraft's operation during flight. The AHRS primarily controls and provides information regarding attitude, rate of turn, and skid/slip.

Attitude refers to the aircraft's orientation in three-dimensional space — specifically, how it is pitched, rolled, and yawed relative to the horizon. This is crucial for maintaining controlled flight and ensuring the aircraft is in the desired position relative to its intended flight path.

The rate of turn is the speed at which the aircraft is changing its heading. This measurement is essential for pilots to execute turns safely and effectively, maintaining proper altitude and ensuring that the aircraft remains coordinated and stable during the turn.

Skid/slip refers to the side-to-side movements that can occur during turns, indicating whether the aircraft is flying straight or banked. This information helps pilots maintain coordinated flight, which is vital for avoiding unwanted aerodynamic effects such as losing control or entering a stall.

In summary, the AHRS plays a critical role in providing real-time data on attitude, rate of turn, and the balance of the aircraft, thereby ensuring safe and efficient flight operations.
