Vertical speed indicator, cabin altimeter, and cabin rate-of-change indicator

Vertical speed indicator, altimeter, and airspeed indicator

The pitot-static system is crucial in providing pilots with accurate flight information related to altitude and airspeed. The correct instruments connected to this system are the vertical speed indicator, altimeter, and airspeed indicator.

The vertical speed indicator measures the rate of climb or descent, providing critical information about the aircraft's vertical performance. The altimeter, which relies on changes in atmospheric pressure sensed through the static line, indicates the aircraft's altitude above sea level. The airspeed indicator uses the dynamic pressure from the pitot tube in conjunction with the static pressure from the static port to determine the aircraft's speed relative to the air around it.

Understanding these functions highlights why these instruments are integral to the pitot-static system, as they all rely on the same pressure inputs to deliver essential data to the pilot.
