The mission computer system (MC1) receives altitude information from which source?

The mission computer system (MC1) receives altitude information from which source?

• A. Altitude information from the pitot-static system.
• B. Altitude information from the electronic altimeter system.
• C. Altitude information from GPS data.
• D. Altitude information is not used by MC1.

Answer: (B)

Altitude information for the MC1 comes from the electronic altimeter system. The pitot-static system provides raw air-pressure data, but the electronic altimeter processes that data into a calibrated altitude value and feeds that finished figure to the mission computer. GPS can supply a vertical position in some setups, but the MC1 in this context relies on the electronic altimeter’s reading as the authoritative altitude source.
