An FAA field office staffed with Flight Standards personnel. ACDOs serve the aviation industry and general public on matters related to the certification and operation of scheduled air carriers and other large aircraft operations.
Industry:Aviation
An FAA-approved document published by the airframe manufacturer that lists the operating conditions for a particular model of aircraft. Engine operating parameters are included in the POH.
Industry:Aviation
An FAA-approved manual that must be in an aircraft any time it flies. The flight manual contains information regarding speed limitations, weight and balance, allowable maneuvers, engine operating limits, and other limitations that apply to the specific aircraft.
Industry:Aviation
An ICAO term for an air traffic control facility primarily responsible for ATC services being provided IFR aircraft during the en route phase of flight. The U.S. equivalent is an air route traffic control center (ARTCC).
Industry:Aviation
An ideal body which absorbs all the light that falls on it. It appears perfectly black at all wavelengths because it does not reflect any wavelength of light.
Industry:Aviation
An ignition system malfunction caused by a fine track of carbon deposited inside the distributor of an aircraft magneto.
The resistance of the air inside the distributor at high altitude is so low that it is possible for a spark to jump between the distributor terminals. As this spark moves across the surface of the distributor block, it leaves a thin track of carbon. The resistance of this carbon track is so much lower than that of the material of which the distributor block is made that high voltage leaks through it during normal engine operation. This high-voltage leakage can cause misfiring, loss of engine power, and possible engine damage.
Industry:Aviation
An ignition system of an aircraft reciprocating engine that has two of every critical unit, including two spark plugs in each cylinder.
Dual ignition provides safety in the event of one system malfunctioning, but more important, igniting the fuel-air mixture inside the cylinder at two locations provides more efficient expansion of the air in the cylinder.
Industry:Aviation
An ignition system problem in which the high voltage in the magneto distributor jumps to the wrong terminal. Flashover causes the wrong spark plug to fire, and this reduces the engine power and produces vibration and excessive heat.
Flashover is often caused by moisture inside the distributor, but it also occurs when flying at high altitude where the air inside the distributor does not have enough density to act as an effective dielectric. Physically large distributors, low-tension ignition systems, and pressurized distributors have been used to prevent flashover.
Industry:Aviation
An image formed on a radarscope by energy reflected or scattered from a target.
Industry:Aviation
An imaginary center line about which a body or object is symmetrical, or has the same
shape on either side.
