Which information is NOT depicted by the Air Data Computer (ADC)?

The Air Data Computer (ADC) is designed to process and provide various critical flight data based on the inputs it receives from sensors in the aircraft. This includes calculating and displaying airspeed, altitude, and vertical speed, which are fundamental parameters for flight operations.

Airspeed is determined from dynamic pressure measured from pitot tubes, allowing the ADC to compute the current speed of the aircraft through the air. Altitude is typically derived from static pressure and is crucial for maintaining a desired flight level. Vertical speed, indicating how quickly an aircraft is climbing or descending, is again based on changes in static pressure over time.

In contrast, yaw rate, which measures the rate of rotation around the vertical axis of the aircraft, is generally obtained from a gyroscopic sensor or an inertial measurement unit, rather than from the air data system. As such, the Air Data Computer does not provide yaw rate information, making it the correct choice for the information not depicted by the ADC.
