Which component of the GPWS interface provides altitude rate and Mach information?

The Air Data Computer (ADC) is responsible for measuring and processing various types of flight data, including altitude, airspeed, and Mach number, which indicates the aircraft’s speed relative to the speed of sound. The ADC takes inputs from various sensors and provides this crucial information to multiple systems, including the Ground Proximity Warning System (GPWS).

By supplying altitude rate and Mach information, the ADC plays a vital role in enhancing situational awareness for pilots and assists in preventing terrain and obstacle conflicts. The altitude data is particularly important for maintaining safe flight levels, while Mach information helps pilots manage the aircraft's performance efficiently, especially at higher speeds.

Other components such as the Flight Control Computer, Terrain Awareness System, and Navigation Management System have specific functionalities but do not offer the same comprehensive altitude rate and Mach information as the ADC. Understanding the role of the ADC is essential for insights into how various systems interact in ensuring safe aircraft operation.
