What factors does the TAD use to make adjustments?

The correct choice is based on the comprehensive understanding of how the TAD (Torque Adverse Yaw) system functions in aircraft operations. The TAD actively monitors various flight parameters to maintain stability and control, particularly during turns.

Torque, altitude, pitch rate, and airspeed are all critical factors that influence an aircraft's performance and handling characteristics. When the torque generated by the engine changes, it affects the yawing motion of the aircraft, which can lead to undesirable flight dynamics if not compensated for.

Altitude is also essential because it impacts air density and, in turn, the aircraft's aerodynamic performance. Pitch rate is a measure of how quickly the aircraft is changing its pitch, and it can indicate how the aircraft is responding to control inputs. Airspeed, being a fundamental aspect of flight dynamics, directly influences lift and drag characteristics, which are crucial when making adjustments to ensure smooth and controlled flight.

The combination of these factors allows the TAD to make precise adjustments, enhancing flight safety and performance. Understanding the interplay of these elements is vital for effective aircraft management, especially in variable flight conditions.
