A system that spreads a mixture of alcohol and glycerin along the propeller blades when the aircraft is flying in icing conditions. The alcohol and glycerin prevent water reaching the metal of the propeller blade and freezing on it.

A system that uses satellite relay, data link, high frequency, or other approved communication system which extends beyond line of sight.

A system that warns the pilot when the angle of attack of the wing reaches a point that will likely produce a stall. Stall warning systems measure the angle of attack. Some systems use a small air-operated vane on the leading edge of the wing to detect the high angle of attack. Others use an angle of attack probe on the fuselage. A few of the smaller airplanes have a reed-type horn in the wing that changes its sound as the angle of attack changes.
Some stall warning systems turn on a light or sound a warning horn when the angle of attack gets too near the angle that could cause a stall. Some of the more elaborate systems, called stick shakers, vibrate the control column, and stick pushers actually push the control column forward when a stall is approached.

A system used for changing decimal numbers into binary numbers. Each digit from 0 through 9 is represented with four binary digits:
Decimal Binary Decimal Binary
: 0 = 0000 5 = 0101
: 1 = 0001 6 = 0110
: 2 = 0010 7 = 0111
: 3 = 0011 8 = 1000
: 4 = 0100 9 = 1001
The decimal number 126 for example, expressed in BCD, is: 0001 0010 0110.

A system used to identify and characterize the different air masses according to a basic scheme.
The system most commonly used classifies air masses primarily according to the thermal properties of their source regions: tropical (T); polar (P); and Arctic or Antarctic (A). They are further classified according to moisture characteristics as continental (c) or maritime (m).
Industry:Aviation
A system used with some of the large reciprocating engines in which a mixture of water and alcohol (methanol) is sprayed into the engine with the fuel when operating at extremely high power.
The fuel-air mixture is automatically leaned to allow the engine to develop its maximum power, and the ADI fluid absorbs the excessive heat when it vaporizes.
ADI does not increase the engine power, but, by absorbing some of the heat released during full-power operation, the engine is able to develop more power without detonating.
Industry:Aviation
A system whose output does not change in the same proportion as the input. If the output voltage of a system changes as the square of the input voltage, the system is nonlinear.
Industry:Aviation
A systematic and sequential list of all operations that must be performed to properly accomplish a complex task. Checklists are used in preflight inspections as well as 100-hour and annual inspections of aircraft, to ensure that no required operation is overlooked.
Industry:Aviation
A systematic check of an aircraft and its components.
The purpose of an aircraft inspection is to detect any defects or malfunctions before they become serious. Preflight, 100-hour, annual, and progressive inspections are the most commonly used types of aircraft inspections.
Industry:Aviation
A systematic set of rules or processes by which a problem can be solved in a specific number of individual steps.
