Aircraft Instrument

Question 1

Combined system
that utilizes the
static air pressure
and the dynamic
pressure due to
the motion of the
aircraft through
the air

Answer 1

Pitot-Static Instruments

Question 2

An instrument that measures
the height of an aircraft
above a given pressure leve

Answer 2

Altimeter

Question 3

read directly from the
altimeter (uncorrected) when it is set to the
current altimeter setting.

Answer 3

Indicated altitude

Question 4

the vertical distance of the
aircraft above sea level. Often expresses as
feet above mean sea level (MSL)

Answer 4

True altitude

Question 5

the vertical distance of an
aircraft above the terrain, or above ground
level (AGL)

Answer 5

Absolute altitude

Question 6

: the altitude indicated when
the altimeter setting window is adjusted to
29.92” Hg or 1013 hPa. This is the altitude
above the standard datum plane.

Answer 6

Pressure altitude

Question 7

pressure altitude corrected for
variations from standard temperature. If
temperature is above standard, density
altitude is higher than pressure altitude and
vice versa

Answer 7

Density altitude

Question 8

Sometimes called a vertical
velocity indicator (VVI),
indicates whether the aircraft
is climbing, descending, or in
level flight.

Answer 8

Vertical Speed Indicator (VSI)

Question 9

Rate of climb or descent is
indicated in

Answer 9

feet per minute
(fpm)

A sensitive, differential
pressure gauge that
measures and promptly
indicates the difference
between pitot and static
pressure.
