Name the instruments connected to the pitot-static system.

• A. Airspeed indicator, altimeter, vertical speed indicator
• B. Attitude indicator, heading indicator, turn coordinator
• C. Airspeed indicator, altimeter, turn coordinator
• D. Airspeed indicator, altimeter, vertical speed indicator

Answer: (D)

The pitot-static system provides pressure information that feeds three instruments: the airspeed indicator uses the ram pressure from the pitot tube plus static pressure as a reference to calculate airspeed; the altimeter uses static pressure to indicate altitude; and the vertical speed indicator uses changes in static pressure to show the rate of climb or descent. The other instruments listed are gyroscopic or attitude/heading devices that do not rely on pitot-static pressure. So the instruments connected to the pitot-static system are the airspeed indicator, the altimeter, and the vertical speed indicator.
