An oxygen system used for emergency or backup use. Solid blocks of a material that releases oxygen when burned are carried in special fireproof fixtures. When oxygen is needed, the candles are ignited with a built in igniter, and oxygen flows into the tubing leading to the masks.
Industry:Aviation
An unbalanced atom having more electrons spinning around the nucleus than there are protons in the nucleus.
Industry:Aviation
An unbalanced electrical condition caused by a deficiency of electrons. A positive charge can be produced by chemical cells, photocells, and thermocouples.
Industry:Aviation
An unbalanced electrical condition caused by there being more electrons than there are protons.
“Negative contact” (air traffic control). A term used by pilots to inform ATC that the previously issued traffic is not in sight, or they are unable to contact ATC on a particular frequency.
Industry:Aviation
An undesirable condition in an automatic flight control system in which the system oscillates back and forth on either side of a stable condition. The control system seeks, or hunts for, its stable condition, but each time it approaches it, it overshoots and must seek it again.
Industry:Aviation
An undesirable condition, also known as cross modulation, in which the output from one system or part of a system is fed over into another system. The output contains the signal that has been fed into it as well as the desired signal.
Cross talk occurs when signals on one channel or circuit are unintentionally fed over so they appear on another channel or in another circuit.
Industry:Aviation
An undesirable, low-amplitude oscillation about both the yaw and roll axes that affects many swept wing airplanes. Dutch roll is minimized by the use of a yaw damper.
Industry:Aviation
An ungrounded, half-wave antenna whose resonant frequency is determined by its distributed capacity. This capacity, and therefore its resonant frequency, is determined by the antenna length.
Industry:Aviation
An uninterrupted descent (except where level flight is required for speed adjustment; e.g., 250 knots at 10,000 feet MSL) from cruising altitude or flight level to the interception of a glideslope or to a minimum altitude specified for the initial or intermediate approach segment of a nonprecision instrument approach. The profile descent normally terminates at the approach gate where the glideslope or other appropriate minimum altitude is intercepted.
Industry:Aviation
An unmanned facility at an airport designed for pilot self-service briefing, flight planning, and filing of flight plans.
