Static ports function to

Static ports function to

• A. Sense atmospheric pressure and use one or more ports on each side of the fuselage
• B. Measure ram air pressure
• C. Sense cabin pressure and provide air conditioning
• D. Convert static pressure to electrical voltage

Answer: (D)

Static ports provide the ambient atmospheric pressure that the aircraft uses as a reference for its instruments. In modern systems, that pressure information is sent to a static pressure transducer, which converts the pressure into an electrical signal (often a voltage) that drives the instrument readings and avionics. So, the role of the static ports can be understood as supplying static pressure to be converted into an electrical signal for the flight instruments. This differs from ram air pressure, which comes from the pitot tube, and from cabin pressurization or air conditioning, which are separate systems.
