CAF 101 Theory of Flight Instruments ALIAC PROPERTY Unauthorized Reproduction & Dissemination is prohibited 6 BASIC FLIGHT INSTRUMENTS ALIAC PROPERTY Unauthorized Reproduction & Dissemination is prohibited  FLIGHT INSTRUMENT - Are instruments installed in the cockpit of an aircraft that provide the pilot with the data about the flight situation of the aircraft. 1. Airspeed Indicator 2. Attitude Indicator 3. Altimeter 4. Turn Coordinator or Turn and Slip Indicator 5. Heading Indicator 6. Vertical Speed Indicator ALIAC PROPERTY Unauthorized Reproduction & Dissemination is prohibited  FLIGHT INSTRUMENT - Are instruments installed in the cockpit of an aircraft that provide the pilot with the data about the flight situation of the aircraft. 1.

PRESS (MW) URE -the pressure (Force) exerted in every direction by the weight of the atmosphere.(MW) ALIAC PROPERTY Unauthorized Reproduction & Dissemination is Atmospheric pressure -force or Weight exerted on any object by the column of air above the object. Pressure decreases from the point of measurement at sea level to the top of the atmosphere. TEMPERATU RE -Degree of hotness or coldness measured on a definite scale. “COLD” “HOT” Why is it hotter at lower altitudes? SUN “Terrestrial Radiation” Earth DENSI -mass per unit volume. TY -amount of matter present in a given volume. “LESS DENSE” “MORE DENSE” Mercury Barometer Consists of a glass tube, sealed at one end, and contains Mercury (Hg). It has an open end immersed in an open Mercury reservoir in the form of a dish.  At mean sea level: Standard Barometric pressure of Internatio 29.92 in. Hg. (1013.25 hPa or millibars)/ 14.7 lbs/in² nal Standard Temperature of 15˚C Standard (59˚F) Atmosphe Mean sea level- The level of the surface of the sea especially at Standard lapse rates: Standard pressure lapse rate: 1 in. Hg/ 1000ft. re its mean position midway between mean high and low water Standard temp. lapse rate: 2°C/1000ft (1.98°C) or 3.5°F/1000ft END ALIAC PROPERTY Unauthorized Reproduction & Dissemination is
