Pitot Tube Cover (5/16" Cap) w/ 12" Remove Before Flight Safety Streamer

[Music] damn hear from you escort flight academy bring you a quick lesson on the pitot static system three instruments are powered by the pitot static system the airspeed indicator the altimeter and the vertical speed indicator for vsi the airspeed indicator is the only instrument that uses both the pitot tube and Static port it measures ram air pressure versus static pressure to give us our airspeed the altimeter only uses the static for it to measure your altitude it uses aneroid wafers that expand as a static air pressure decreases and it contracts of the air pressure increases the vsi works by measuring differential pressure using a diaphragm and a calibrated leak through a small hole the size of the hole restricts the airflow so it can't move in and out as fast as the diaphragm can this creates a pressure differential that causes a needle to move this is also where we get our trend
