Which ADS system would primarily utilize TAT 1 and ADSP 1/2?

The correct choice, ADS 1, accurately represents the system that primarily utilizes Total Air Temperature (TAT) 1 and Air Data Sensor Probes (ADSP) 1 and 2. ADS 1 is responsible for collecting critical airspeed, altitude, and temperature data, which are essential for flight operations.

TAT 1 provides the necessary temperature measurement for flight performance calculations, and the ADSPs function to measure total pressure and static pressure for determining airspeed and altitude. By integrating data from these sources, ADS 1 can deliver accurate information required for the aircraft's air data systems and enhance overall operational safety and efficiency.

While the other options refer to alternative versions or iterations of the aircraft's air data system, they do not utilize TAT 1 and ADSP 1/2 in the same way that ADS 1 does, which makes it the correct answer in this context.
