Summary:
The pitot static system measures the static air
pressure, rate of change of static air pressure,
and the difference between pitot tube air
pressure and static pressure to provide Mach/
airspeed, altitude, and rate-of-climb information.
The flight instruments receiving pitot static input
are the altimeter, the Mach/airspeed indicator,
the VSI, and the HUD.
