A weather observation in which winds are measured by radar tracking a balloon-borne target.
Industry:Aviation
A weather radar designed to detect hydrometeors of precipitation size. Storm-detection radar is used primarily to detect storms containing large drops of water or hailstones, as opposed to clouds and light precipitation of small drop size.
Industry:Aviation
A weight permanently installed in an aircraft to bring its center of gravity into allowable limits.
Industry:Aviation
A weight permanently installed in an aircraft to move the center of gravity to a location within its allowable limits.
Industry:Aviation
A weight suspended on a rod or cable from a fixed point, free to swing back and forth. The period of a pendulum, the time required for one complete swing, is determined by its length. A pendulum is used as the regulating device in a clock because the period of a fixed-length pendulum is always the same.
The clock spring or weights add a tiny bit of energy to the pendulum each time it swings, and by adding as much energy as the pendulum loses because of friction, the pendulum can be kept swinging.
Industry:Aviation
A welded joint in an aircraft steel-tube fuselage made where a number of tubes meet at a common point.
Industry:Aviation
A welding torch in which the oxygen and fuel gas are supplied at the same pressure. Each gas has its own valve to control the amount delivered to the tip.
Industry:Aviation
A west wind or the westerly component of a wind. Zonal wind is conventionally used to describe large-scale flow that is neither cyclonic nor anticyclonic.
Industry:Aviation
A wheel fitted with vanes, or buckets, radiating out from its circumference. Kinetic energy in a fluid flowing through the vanes is converted into mechanical power by the impulse or reaction of the fluid with the vanes.
Industry:Aviation
A wheel-like control in an airplane cockpit used by the pilot to move the ailerons and elevators. Rotation of the wheel moves the ailerons, and back-and-forth or in-and-out movement moves the elevators. Because the wheel does not rotate in a complete circle, most aircraft control wheels are not round, but are, rather, only segments of a wheel.
