A material whose permeability is greater than that of a vacuum (permeability of one) but less than that of a ferromagnetic material. The permeability of a paramagnetic material does not change as the magnetizing force applied to it changes. Some alloys of nickel and titanium are paramagnetic.
Industry:Aviation
A material with a high coefficient of friction and the ability to maintain its friction and strength when it is hot. Brake linings were at one time made with asbestos, but modern brake linings contain no asbestos.
Industry:Aviation
A material with a negative temperature coefficient that causes its resistance to decrease as its temperature increases.
Industry:Aviation
A material, such as microballoons, added to a resin to give it body and increase its workability.
Industry:Aviation
A material, such as silica gel, that is able to absorb moisture from the air. When precision equipment is stored, bags of silica gel are packed with it. The silica gel absorbs moisture from the air and prevents the moisture damaging the equipment.
In pneumatic power systems, the high-pressure compressed air passes through a desiccant which absorbs all the moisture in the air. If moisture were left in the air, it would freeze when the air expands and its temperature drops.
Industry:Aviation
A material, such as synthetic rubber, that can be stretched at room temperature to at least twice its original length. When it is released, it will return to its original size and shape.

A mathematical curve plotted in such a way that the coordinate of any point varies as the logarithm of the other coordinate.

A mathematical fraction with whole numbers for both its numerator and its denominator. An example of a simple fraction is 3/4. Fractions that are not simple fractions are called complex fractions. An example of a complex fraction is: 1/2 / 3/4.

A mathematical time saver used when working with very large and very small numbers. When using scientific notation, all numbers are changed into a positive number between one and 10 by moving the decimal point and attaching the number ten, raised to the power showing the number of places the decimal has been moved.
A negative (minus) number is used if the decimal was moved to the right, and a positive number is used if it is moved to the left. Using this system, 1,000 = 1 · 103, and 0.001 = 1 · 10-3.
Industry:Aviation
A mathematically derived runway capacity standard.
EPS’s are calculated for each airport on an individual basis and reflect that airport’s aircraft mix, operating procedures, runway layout, and specific weather conditions. EPS’s do not give consideration to staffing, experience levels, equipment outages, and in-trail restrictions as does the airport acceptance rate (AAR).
