ANEROID – sensitive component in an altimeter or barometer that measures absolute pressure of the air. -Sealed, flat capsule made of thin corrugated disks of metal soldered together and evacuated by pumping all of the air out of it.
PRESSURE – amount of force acting on a given unit of area and all pressure must be measured from some known references.
BAROMETRICSCALE/KOLLSMAN WINDOW- small window in the dial of a sensitive altimeter in which the pilot sets the barometric pressure level from which the altitude shown on the altimeter is measured.
AIRSPEED INDICATOR – A flight instrument that measures the differential between the pitot, of ram air pressure and the static pressure of the air surrounding the aircraft.
BOURDON TUBE – type …show more content…

ISOGONIC LINE – a line drawn on an aeronautical chart along which the angular difference between the magnetic and geographic north poles is the same.
AGONIC LINE – a line drawn on an aeronautical chart along which there is no angular difference between the magnetic geographic north poles.
RATE GYROS – mounted in single gimbals and they operate on the characteristic of precession.
