Final answer:
The pitot static system supplies variable air pressure inputs to the altimeter, vertical speed indicator, and airspeed indicator, thereby providing pilots with vital flight data.
Step-by-step explanation:
The pitot static system supplies variable air pressure inputs to all of the above mentioned devices: (a) Altimeter, (b) Vertical Speed Indicator, and (c) Airspeed Indicator. The system captures static and dynamic pressures to provide pilots with accurate altitude, vertical speed, and airspeed readings. The function of the pitot static system is to measure the pressure levels that correlate to speed and altitude. Specifically, the airspeed indicator measures the difference between the dynamic pressure captured at the pitot tube’s front-facing opening and the static pressure from a separate port, the altimeter measures static pressure to determine altitude, and the vertical speed indicator measures the rate of change in static pressure to deduce the rate of climb or descent.
