AVIT 323-255 ORAL EXAM 3 MOCK ORAL
QUESTIONS WITH MODEL RESPONSES 2026
◉ Calibrated airspeed.
Answer: indicated airspeed corrected for installation errors
◉ True airspeed.
Answer: Calibrated airspeed corrected for altitude and nonstandard
temperature
◉ Equivalent airspeed.
Answer: calibrated airspeed corrected for compressibility
◉ Indicated altitude.
Answer: the altitude read on the altimeter given a Kolsman window
setting
◉ Absolute altitude.
Answer: Altitude of the airplane above the Earth's surface (AGL)
◉ True altitude.
,Answer: the altitude of the aircraft above mean sea level (MSL
altitude)
◉ Pressure altitude.
Answer: the altitude of the aircraft above the standard datum plane
(29.92" Hg)
◉ Vertical speed indicator.
Answer: diaphragm in this instrument receives direct static
pressure. it has a CALIBRATED LEAK that lets air into the CASE at a
slower rate than what goes into the instrument's diaphragm. this
creates a pressure differential that causes the diaphragm in the
instrument to expand/contract, which turns gears and linkages to
display the needle indicating a climb/descent
◉ sensitive altimeter.
Answer: a ground adjustable barometer that has sealed aneroid
wafers that expand and contract based on the static pressure inside
the case.
◉ Attitude indicator.
Answer: gyroscopic instrument. works on the principle of rigidity in
space. usually vacuum driven. only instrument that shows pitch AND
bank at the same time. Aircraft rotates AROUND the gyroscope
, ◉ Heading indicator.
Answer: Indicates the aircrafts heading in relation to magnetic
north. Usually vacuum driven, and relies on the rigidity in space
principle
◉ Rigidity in space.
Answer: A spinning gyroscope is held in place by the rotational force
of the spin.
◉ Gyroscopic precession.
Answer: A force applied to a spinning gyroscope is felt 90 degrees in
the direction of rotation from which the force is applied.
◉ Turn and slip indicator.
Answer: Indicates QUANTITY of turn. usually electrically powered.
This instrument relies on the principle of gyroscopic precession.
◉ Turn Coordinator.
Answer: Indicates QUALITY of turn. The gyroscope in this
instrument is mounted at a 30 degree angle, which allows it to sense
roll AND yaw. Usually electrically powered. Relies on the principle of
gyroscopic precession.
◉ True altitude equation.
