The location near, but not at, the south geographic pole, at which the magnetic lines of flux of the earth’s magnetic field enter. These lines of flux are considered to leave from the north magnetic pole and enter at the south magnetic pole.
Industry:Aviation
The location of the southern spin axes of the earth. The south geographic pole is located at 90° south latitude.
Industry:Aviation
The location on a navigational chart to which a VORTAC station has been electronically moved by an Area Navigation (RNAV) system. A waypoint is located by keying in the radial from the VORTAC station on which the waypoint is to be located, and the distance in nautical miles from the station along the selected radial.
By using waypoints, rather than flying directly to the physical station, a flight can be made in a straight line, and radio navigation can be used directly to a destination having no radio facility. A waypoint may be defined relative to a VORTAC station or in terms of latitude/longitude coordinates.
Industry:Aviation
The location on the earth near the north geographic pole to which compass magnets point. The earth is a huge magnet spinning about its axis in space. Lines of magnetic flux leave the earth at its magnetic north pole and enter at its magnetic south pole, a location near its south geographic pole. Magnetic compasses align with this magnetic flux, with one end pointing to the magnetic north pole.
Industry:Aviation
The location on the surface of an aircraft where the static air pressure used in the altimeter, airspeed indicator, and the vertical speed indicator is picked up. Static pressure is often taken from flush static ports on the sides of the fuselage or on the sides of the vertical tail surface. In other installations, static pressure is picked up from ports in the side of a combination pitot-static tube.
Static pressure pickups must be located in an area where there is no movement of air in a direction that could blow into the static holes.
Industry:Aviation
The location within a body at which its entire mass is considered to be balanced.
Industry:Aviation
The locations on a magnet at which the lines of flux leave and enter. All magnets have both a north pole and a south pole. The lines of flux leave the magnet at right angles to the face of the north pole and enter at right angles to the face of the south pole.
Industry:Aviation
The locations on a magnet where the lines of magnetic flux leave and where they enter. In a ferromagnetic metal, groups of atoms whose electrons have their spin axes in alignment are called magnetic domains. When all of the domains are aligned in the same direction, the material is magnetized.
All magnets, regardless of their size, have two poles, a north pole and a south pole. Lines of magnetic flux leave the magnet at its north pole and return through its south pole. All the lines of flux leave and enter the poles at right angles to the surface.
Industry:Aviation
The logic condition of a conductor in a piece of digital electronic equipment — that is, whether the conductor is carrying a logic zero or a logic one.
Industry:Aviation
The long visible trail resembling a cloud left behind some airplanes as they fly at high altitude. Contrails form when water vapor from the hot engine exhausts condense and freeze into tiny ice crystals. These crystals reflect light from the sun and form the visible track across the sky.
