Which aircraft instruments are typically connected to the pitot-static system?

The instruments that are typically connected to the pitot-static system are the altimeter, vertical speed indicator, and airspeed indicator. The pitot-static system is critical for measuring various atmospheric pressures, which are essential for accurate performance readings in aviation.

The altimeter measures the aircraft's altitude by comparing the static pressure outside the aircraft to a preset standard pressure. The vertical speed indicator uses the static pressure information to determine how quickly the aircraft is ascending or descending. The airspeed indicator relies on dynamic pressure from the pitot tube, which measures the difference between static and total pressure to display the aircraft's speed.

This setup allows pilots to receive vital information about their flight environment, contributing to operational safety and control.
