What are the major components of the pitot-static system?

The major components of the pitot-static system are indeed the impact and static pressure chambers, along with the associated lines. This system is crucial for measuring airspeed and altitude in an aircraft.

The pitot-static system operates by gathering data from the environment around the aircraft. The pitot tube measures dynamic pressure, which is directly related to the aircraft's airspeed, while the static port measures static pressure, which is essential for altitude readings and understanding air density. These measurements are transmitted through lines to instruments like the airspeed indicator, altimeter, and vertical speed indicator, thereby providing vital flight information to the pilot.

Understanding these components is fundamental because accurate readings from the pitot-static system are essential for safe flight operations, particularly during critical phases like takeoff, landing, and in various weather conditions. The other options offered do not pertain to measuring airspeed or altitude and are unrelated to the functionality of the pitot-static system.
