Avit 415 Stage 18 Exam Questions and
Answers with Verified Solutions | Latest
Updated 2026
Comprised of the Airspeed Pitot Static Sysem
Indicator, Altimeter, and VSI.
Measurement of change in How does the Airspeed Indicator
ram air to static and displayed Operate?
through mechanical linkage.
an aneroid wafer expands and How does the Altimeter operate?
contracts as atmospheric
pressure changes and is
displayed through a shaft and
gear linkage.
In a climb or descent air How does the VSI operate
pressure immediately escapes
outside the diaphragm while a
calibrated leak slowly releases
air outside the casing. This
causes a slow change in the
diaphragm and display on the
display.
Indicated-Read right off the Types of Airspeed
instrument
Calibrated-correction for
instrument or position error
Equivalent- 250k or 10000
, True Airspeed-Corrected for
non standard temperature or
pressure
Indicated-instrument read Types of altitude
True-altitude above sea level
absolute-Distance above
terrain Pressure-distance
above standard datum plane
density-pressure altitude
corrected for variation from
standard temperature
Rigidity in Space-Preventing a Gyroscopic Principles
gyro's axis to tilt as the Earth
Rotates Precession-applied
force is felt 90 degrees from
application
Works off rigidity in space. Heading Indicator operation
Fixed through mechanical
linkage to a compass card,
double gimbaled and rotates
about the vertical axis to
display heading information.
Work off rigidity in space. Attitude Indicator operation
Horizontally mounted and
measures pitch and bank
about the lateral or
longitudinal axis
displays rate of turn and rate Turn coordinator operation
of roll through precession.
