AVIT 222 Stage 131 Exam Questions With
Accurate Answers
What is the purpose of Anti-Ice? - ANSWER Prevents the formation of ice.
What is an example of an Anti-Ice system? - ANSWER Heat/Defrost.
What is the purpose of De-Ice? - ANSWER Removes ice already present on critical
surfaces.
What is an example of a De-Ice system? - ANSWER Pneumatic Boots.
What instruments are part of the Pitot-Static system? - ANSWER Airspeed Indicator
Altimeter
VSI
How does the airspeed indicator work? - ANSWER It measures dynamic pressure, which
is the difference between the Ram Air Pressure from the pitot tube and Static Air
(Ambient) Pressure from the static port.
How does the altimeter work? - ANSWER Inside the altimeter are sealed aneroid wafers.
As the barometric pressure increases/decreases, it causes the wafers to expand or
contract. As the pressure decreases, the aneroid wafers expand and indicate an
increase in altitude, and vice-versa.
What is the device used to "tune" the altimeter? - ANSWER Kollsman Window
How does the VSI work? - ANSWER There is a diaphragm in the VSI that is connected to
the static source. The area around the area also receives static pressure by a calibrated
, leak. As the diaphragm expands/contracts, the indicator moves to display the current
rate of climb.
What instruments use PITOT pressure? - ANSWER Airspeed Indicator
What instruments use STATIC pressure? - ANSWER Airspeed Indicator
