Systems in an aircraft which make it possible for the occupants to operate in an environment that does not support life. Oxygen systems and pressurization systems are examples of life-support systems.
Industry:Aviation
Tactics used in military aircraft to evade or deceive enemy radar. Chaff, made of strips of metal foil or metalized glass fibers, is released to form a large radar return to decoy the enemy radar away from the true target.
Electromagnetic radiation over a wide band of frequencies can prevent the enemy receiving radio transmissions. This form of ECM is called jamming.
Industry:Aviation
Tactics used in military aircraft to reduce the effectiveness of the countermeasures used by the enemy against electronic countermeasures.
Industry:Aviation
Tapered metal cones placed over a splined propeller shaft to hold the propeller centered on the shaft. A single-piece bronze cone is used as the rear cone and it slips over the shaft and contacts the thrust bearing retainer nut that is screwed onto the propeller shaft. The front cone is a two-piece, chrome-plated steel, matched set. It contains a groove into which a flange on the propeller retaining nut fits.
When the retaining nut is tightened, the propeller hub is squeezed between the two cones which centers it on the shaft.

Taxiways and apron (ramp) areas not under the control of air traffic.

Temperature lower than that needed to cause water to freeze.
Industry:Aviation
Temperature measured by a thermometer not affected by the evaporation of water. Relative humidity is measured by finding the difference between wet-bulb and dry-bulb temperature.
The thermometer that measures wet-bulb temperature has a wick around its sensitive end. This wick is saturated with water, and air blown across it evaporates the water. The evaporation causes the wet-bulb temperature to be lower than the dry-bulb temperature, and the amount lower is determined by the humidity, or the amount of water vapor in the air.
Industry:Aviation
Temperature measured from absolute zero on a scale using the same divisions as are used in the Celsius system. Water freezes at 273°K and boils at 373°K.
Industry:Aviation
Temperature measured on a scale that sets the freezing point of water at 0° and its boiling point at 100°. There are 100 equal graduations called degrees between these two points. Absolute zero is –273°C. Celsius temperature was formerly called centigrade temperature.
Industry:Aviation
Temperature measured on a scale that uses 32° as the point at which pure water freezes, and 212° as the point at which pure water boils under standard atmospheric pressure. There are 180 equal graduations between the freezing and boiling points of water. Absolute zero (the point at which molecular motion stops) is –460°F.
