A condition in which the aircraft or component meets the conditions of its type design and is in a condition for safe operation.
Industry:Aviation
A condition in which the brakes do not fully release when pressure is removed from the brake pedal. The brakes are partially applied all the time, which causes excessive lining wear and heat.
Dragging brakes can cause serious overheating, and may be caused by a malfunction in the brake master cylinder or by warped disks.
Industry:Aviation
A condition in which the breaker points in an aircraft magneto bounce open, rather than remaining closed when the cam follower moves off of the cam lobe. Breaker-point bounce is caused by a weak breaker-point spring.
Industry:Aviation
A condition in which the effect of gravity is cancelled or nullified by the force of inertia. Zero gravity is felt in a high-performance aircraft when it is flying in a parabolic, or curved, flight path, and in a satellite when it is orbiting the earth.
Industry:Aviation
A condition in which the flame in a gas turbine engine goes out because of an overly rich fuel-air mixture. For fuel to burn in a turbine engine, it must be mixed with air in a ratio of between 8 and 18 parts of air for 1 part of fuel, by weight. If there is either more fuel or more air than this in the mixture, the flame will go out.
Industry:Aviation
A condition in which the flame inside a gas turbine engine goes out because there is not enough fuel for the amount of air flowing through the engine. Turbine engine fuel controls are designed to measure the air flowing through the engine and adjust the fuel flow so a lean flameout, or lean die-out, cannot occur. A lean flameout is also called a lean die-out.
Industry:Aviation
A condition in which the fuel-air mixture inside a gas turbine engine ignites and burns, but the RPM does not build up high enough for the engine to continue to run without help from the starter. A false start, also called a hung start, is caused by the starter not turning the engine fast enough for it to start properly.
Industry:Aviation
A condition in which there are more electrons (negative charges) than there are protons (positive charges). A negative condition is indicated by a minus sign (–) in front of the value. For example, –6 volts is negative six volts.
Industry:Aviation
A condition in which there is an excess or deficiency of electrons on a body. If there is an excess of electrons, the charge is negative. A deficiency of electrons results in a positive charge.
Industry:Aviation
A condition in which there is no complete path for electrons to flow from one terminal of the source of electrical energy to the other terminal.
