Which device senses engine torque, altitude, airspeed, and pitch rate to compute a desired rudder trim tab position?

The trim aid device (TAD) is specifically designed to enhance aircraft stability and control by automatically adjusting the rudder trim tab position based on various flight parameters. It uses inputs such as engine torque, altitude, airspeed, and pitch rate to determine the ideal position for the trim tab, which helps to minimize pilot workload and ensure smoother flight operations.

This device is particularly useful in managing the asymmetrical thrust produced by multi-engine aircraft, where different torque levels can lead to unbalanced flight. By analyzing the real-time data related to engine performance and current flight conditions, the TAD optimizes rudder trim adjustments, allowing for better handling and reduced pilot effort, especially during critical phases of flight like takeoff, climb, and descent.

In contrast, an altitude sensor primarily focuses on measuring altitude, which is essential for various flight calculations but does not actively sense or compute rudder trim requirements. The flight management system oversees overall flight planning and navigation but does not specifically adjust the rudder trim based on torque or airspeed. The air data computer processes information relevant to airspeed and altitude but does not calculate desired rudder trim positions either.
