A condition in which a parameter sensed by the EICAS exceeds the limits for which it is programmed.
Industry:Aviation
A condition in which a physical action lags behind its cause. A spring is often slow to return to its original length when the load is removed. This slow return is caused by friction within the material of which the spring is made. This internal friction causes hysteresis.
Industry:Aviation
A condition in which an aircraft reciprocating engine tries to run after the ignition is turned off. Dieseling normally occurs when the engine is overheated. Carbon particles inside the cylinders become incandescent and ignite the fuel-air mixture in the cylinder and keep the engine running.
Industry:Aviation
A condition in which an increase in voltage across a device causes a decrease in current through it. Under certain operating conditions, a tunnel diode shows negative resistance (the more voltage across it, the less current through it).
Industry:Aviation
A condition in which certain types of metal become brittle from absorbing hydrogen while they are being electroplated.
Industry:Aviation
A condition in which helicopter rotor blades track on the ground and in a hover, but one blade flies higher than the other in flight.
Industry:Aviation
A condition in which oil drains into the lower cylinders of an engine and leaks past the piston rings to fill the combustion chamber. If this oil is not removed before the engine is started, it can cause serious damage.
The propellers on all radial, inverted V-, and inverted in-line engines must be pulled through by hand before they are cranked with the starter to be sure that none of the cylinders have hydraulic lock.
Industry:Aviation
A condition in which something has a level of importance just below that which is most important.
Industry:Aviation
A condition in which something is complete or unbroken. An electrical circuit is said to have continuity when current can flow from one end of the circuit to the other.
