Which system serves as the secondary pitot static systems?

The secondary pitot static systems are critical for ensuring accurate readings of airspeed and altitude in case the primary systems fail. In this context, the correct choice indicates that the pitot tube is located on the left side of the aircraft while the static port is on the lower right.

This arrangement of the secondary systems is designed for redundancy, allowing the aircraft to maintain functionality despite potential primary system failures. The pitot tube measures dynamic air pressure, essential for calculating airspeed, whereas the static port measures static air pressure to gauge altitude and vertical speed. Having these components on the left and lower right sides of the aircraft ensures they are both optimally positioned to provide reliable readings while also being spaced apart to reduce the risk of both being affected by the same malfunction.

This configuration is specifically chosen to help mitigate the risk of interference from airflow patterns or obstructions that might affect one system but not the other. Overall, the design illustrates a careful balance of functionality, reliability, and safety in aircraft instrumentation.
