What is the purpose of the pitot-static system and what readings may indicate a problem?

The pitot-static system provides the airspeed information from the pitot tube and the altitude and vertical speed information from the static pressure port. These readings are essential for basic flight calculations and instrument indications. If something in the system isn’t functioning properly, you’ll typically see erratic or unreliable indications on the airspeed indicator and the altimeter/VSI. A blocked or leaking pitot line usually causes the airspeed indicator to behave strangely (it can read too high, too low, or even zero or freeze). A compromised static system affects the altimeter and the vertical speed indicator, causing the altitude to appear incorrect or not to change as you climb or descend, and the VSI to show improper rates. When these readings don’t correlate with the actual flight conditions, that signals a system issue. Note that this system does not provide cabin temperature or attitude information, and the readings do influence flight calculations by driving the airspeed, altitude, and rate-of-climb indicators.
