Static air is always present whether aircraft is moving or at rest. Dynamic pressure is only present when an aircraft is in motion. What is the air speed indicator? - ....ANSWER ...-It is the speed indicated based on the dynamic pressure. There is static pressure delivered to both sides of the tube which cancels out static pressure and leaving dynamic to be displayed on instrument. What two flight instruments use static pressure? - ....ANSWER ...-Altimeter and VSI What happens if the primary static source becomes blocked? - ....ANSWER ...- There is a secondary system found in the flight deck and due to the venturi effect the air flowing around the fuselage the air pressure inside the flight deck is lower than exterior pressure. ....FOR STUDY PURPOSES...©️2025 ALL RIGHTS RESERVED... 1
