Flight Instruments
Those that help visualize the attitude, location andspeeds of the aircraft.
Those which indicate the relationship to the air through which we are flying
Those which relate to our position in space
without considering the air.

Pitot-static System
Dynamic Air Pressure - Pressure caused by movingair.
Ambient Static Air Pressure - Pressure of non-moving air just outside the aircraft.

Airspeed Indicator
Differentialpressuregauge thatmeasures thedifferencebetweendynamic andambient static
air pressure.

Airspeed Indicator
Indicated airspeed
The speed of an aircraft as shown on the airspeedindicator.
True airspeed
The speed at which an aircraft is moving relative to thesurrounding air.
Calibrated airspeed
Indicated airspeed of an aircraft, corrected for
installation and instrument errors.

Altimeter
A barometer thatmeasures theabsolute pressure of the air.

Altimeter
Indicated Altitude The altitude shown by an altimeter set to
current altimeter setting.
Pressure Altitude Height above the standard pressure level of
29.92 in.Hg.
Density Altitude Pressure altitude corrected for nonstandard
temperature variations.

Altimeter
True Altitude The actual height of an abject above mean sea
level.
Absolute Altitude Actual height above the surface of the earth,
either land or water.

Vertical Speed Indicator
The rate of climb indicator
Serves only asa backup for thealtimeter andairspeedindicator as apitch indicatinginstrument.
Helps the pilotestablish a rateof climb or descent.

Blockage Of The Pitot-Static System
Pitot Tube Affects only the airspeed indicator, but a
clogged static system affects all three pitot-static instruments.
If the pitot tube is blocked and its drain holeremains open, the airspeed reading will drop tozero.
If both pitot tube and the drain hole clog, theairspeed indicator will react like an altimeter.

Blockage Of The Pitot-Static System
Static port The indicated airspeed increases as the
airplane descends and decreases when itclimbs.
The altimeter: air pressure in the system willnot change and neither will your indicatedaltitude.
VSI continually indicates Zero.

Gyroscopic Instruments Rigidity In Space Once a gyroscope is spinning, it
tends to remain in a fixed position in space andresist external forces applied to it.

Gyroscopic Instruments Precession The
tilting or turning of agyro in response topressure.
The reaction to thisforce occurs in thedirection of rotation,approximately 90 ahead of the pointwhere the force wasapplied.
