Navigation system that uses satellite rather than ground-based transmitters for location information.
Industry:Aviation
The visibility determined for a particular runway by a transmissometer.
Industry:Aviation
As used in radio frequency (RF) antenna systems, a direction-sensing device consisting of two fixed loops of wire oriented 90° from each other, which separately sense received signal strength and send those signals to two rotors (also oriented 90°) in the sealed direction-indicating instrument. The rotors are attached to the direction-indicating needle of the instrument and rotated by a small motor until minimum magnetic field is sensed near the rotors.
Industry:Aviation
The instrumentally derived horizontal distance a pilot should be able to see down the runway from the approach end, based on either the sighting of high-intensity runway lights, or the visual contrast of other objects.
Industry:Aviation
The illusion of the cessation of a turn while still in a prolonged, coordinated, constant rate turn, which can lead a disoriented pilot to a loss of control of the aircraft.
Industry:Aviation
Data broadcast by the GPS satellite containing very accurate orbital data for that satellite, atmospheric propagation data, and satellite clock error data.
Industry:Aviation
The shortest distance across the surface of a sphere (the Earth) between two points on the surface.
Industry:Aviation
The first fundamental skill of instrument flight, also known as “cross-check;” the continuous and logical observation of instruments for attitude and performance information.
Industry:Aviation
Non-movable metal trim tab on a control surface. Bent in one direction or another while on the ground to apply trim forces to the control surface.
Industry:Aviation
A coastal breeze blowing from sea to land caused by the temperature difference when the land surface is warmer than the sea surface. The sea breeze usually occurs during the day and alternates with the land breeze that blows in the opposite direction at night.
