Which function does the Mission Computer perform regarding avionic data?

• A. Data conversion from mux avionic equipment
• B. Data conversion from non-mux avionic equipment
• C. Engine control
• D. Flight control

Answer: (B)

The Mission Computer’s role with avionic data is to translate and normalize inputs from sources that aren’t already sharing a common data format. Non-mux avionic equipment outputs data in various formats and timing, so the MC converts those diverse signals into a single, standard digital representation that the rest of the aircraft systems can use for processing, display, navigation, and control tasks.

Mux (multiplexed) avionics already feed data on a common bus and protocol, so they generally require less conversion for the MC. The MC isn’t performing engine control or direct flight control; those functions are handled by dedicated control systems and actuators.
