What is the purpose of the Pitot/static system?

  • A

    To prevent the buildup of static electricity on the aircraft.

  • B

    To adjust the airspeed indicator to read zero when the aircraft is stationary on the ground.

  • C

    To measure both total and static air pressure.

  • D

    To prevent the Pitot tube from icing up.

Refer to figure.
An aircraft pitot-static system comprises several sensors that detect the ambient air pressure affected (pitot pressure) and unaffected (static pressure) by the aircraft's forward motion. These pressures are used on their own or in combination with each other to provide indications of various flight parameters.
