A junction field effect transistor in which the gate-to-channel junction acts as a photodiode. The light sensitivity of a photofet is about ten times as great as that of an ordinary phototransistor.
Industry:Aviation
A junction transistor in which emitter-collector current flows when light shines on the reverse-biased collector-base junction. A small window in the housing allows light to shine on the junction and control the current. Phototransistors produce a current gain and are often used in place of photodiodes.
Industry:Aviation
A kerosine-type fuel similar to Jet-A fuel except that it contains additives that decrease its freezing point to –58°F. Jet-A1 fuel is used in aircraft that remain at high altitudes for long periods of time. Jet-A1 fuel is similar to NATO JP-8 fuel.
Industry:Aviation
A kerosine-type fuel used in most commercially operated jet-propelled aircraft. Jet-A is similar to military JP-5 fuel. Its flash point is between 110° and 150°F, and its freezing point is –40°F.
Industry:Aviation
A knot that runs through the depth of a beam, perpendicular to the annual rings. Spike knots appear most frequently in quartersawed wood.
Industry:Aviation
A knot used to make individual spot ties for securing a bundle of electrical wires in an aircraft. A clove hitch is actually two half hitches around the wire bundle secured with a square knot.
Industry:Aviation
A L/MF or UHF radio beacon transmitting nondirectional signals. The pilot of an aircraft equipped with direction finding equipment can determine his bearing to or from the NDB and home on or track to or from the station.
Industry:Aviation
A landing in which the aircraft is flared out (leveled off) several feet above the surface of the ground. As the aircraft loses its forward speed and aerodynamic lift, it drops to the ground in a flat attitude.
Industry:Aviation
A landing in which the aircraft is moving in the same direction the wind is blowing. Normal landings are made into the wind, or upwind, allowing the wind to slow the ground speed of the aircraft.
When an aircraft lands into the wind, its ground speed is its airspeed minus the speed of the wind. When it lands downwind, its speed over the ground is equal to its airspeed plus the speed of the wind.
Industry:Aviation
A landing made by an aircraft when the engine is producing no power.
