kerf The slot or groove left by a cutting tool as it cuts through a material.

kerosene A thin, colorless, flammable hydrocarbon material distilled from crude oil and used as a base for turbine engine fuel and as a solvent for cleaning parts.

Kett saw A metal cutting, hand-held, power-operated tool. The head can be turned to any desired angle for cutting sheet stock aluminum. Uses various sizes of blades.

Kevlar Trademark of DuPont. A strong, lightweight aramid fiber used as a reinforcement fiber.

keyhole saw A small U-shaped hand saw with a stiff, narrow blade used to cut a larger hole from a small drilled hole.

keying The process of modulating a continuous carrier wave (cw) with a key circuit to provide interruptions in the carrier in the form of dots and dashes for code transmission.

keyway A slot or groove machined into a hole or a shaft onto which a key is fitted.

Kilo

KILOGRAM

Kidde A manufacturer of fire detection systems.

kilo (K) A metric term used to indicate one thousand. Kilo is also used as the prefix for kilogram, kilometer, and kilohertz.

kilogram (kg) One thousand grams. 1 kg = 1,000 grams.

kilohertz A frequency of 1,000 cycles per second.

kilomega An outdated term for one thousand million (i.e., a billion or 1,000,000,000). Giga is now used.

kilovolt 1,000 volts.

kilovolt amperes reactive (KVAR) A measure of reactive power.

kindling point That temperature at which combustion can take place for a particular fuel/oxygen combination.

kindling temperature The temperature required for a material to burn when combined with oxygen.

kinds of operations list A list found in the pilot s operating handbook (POH) of an aircraft that includes all equipment originally installed in the aircraft at the time of certification. It also includes notations on which equipment must be operational for various types of flight including day and night VFR.

kinematic viscosity The ratio of absolute viscosity and density, expressed in units of centistokes.

kinesthetic learners People who prefer to be doing something and primarily absorb information through actual hands-on experience. Kinesthetic learners ascertain more from performing a preflight inspection than from studying a checklist.

KINETÝC

K
inetic energy

kinetic energy Energy due to motion, defined as one half mass times velocity squared.

kink A sharp twist or bend in a piece of wire, sheet metal, or a piece of tubing.

Kirchhoff s current law The algebraic sum of the currents entering and leaving any junction of conductors is equal to zero. Simply stated, this means that all of the current that arrives at a point must leave that point.

Kirchhoff s voltage law The law of electrical circuits that states the sum of voltage that drops around a series circuit is equal to the applied voltage.

kirksite An alloy of aluminum and zinc.

KNOT1

kite A framework covered with paper, cloth, metal, or other material, intended to be flown at the end of a rope or cable, and having as its only support the force of the wind moving past its surfaces.

Klyston tube An electron tube in which modulation is accomplished by varying the velocity of the electrons flowing through the tube.

knife edge A sharp-edged piece of steel or other hard material used as a balance point or fulcrum for precision balance of a control surface or a propeller.

knife edge filter A piece of metal shaped like a cylinder whose surface is cut with incoming and outgoing sharp cut grooves. When inserted in an oil passageway, contaminants remain in the incoming groove and clean oil squeezes between the knife edge and the casing and through the outgoing groove to the oil jet.

knife edge tip Thin metal rims on a shrouded-tip turbine blade. These sealing tips establish their own clearance to the shroud ring by contact loading and wear.

knife switch A switch that uses a blade that fits between two spring-loaded contacts to complete a circuit. When the blade is rotated out of the slot between the contacts, the circuit is opened.

knock A loud knocking or banging noise made inside a reciprocating engine cylinder during the compression stroke. The knock is an explosion rather than a smooth burning process and is caused by the almost instantaneous release of heat energy from fuel in an aircraft engine caused by the fuel air mixture reaching its critical pressure and temperature.

knot 1. One nautical mile per hour, or 1.1508 statute miles per hour. 2. A round, hard section of a tree branch embedded in a board and that weakens the overall strength of the board.

known traffic With respect to ATC clearances, aircraft whose altitude, position and intentions are known to ATC.

knuckle pin The hardened steel pin that holds an articulating rod in the master rod of a radial engine.

knurl A series of small ridges on the surface of a material to aid in gripping.

Kollsman window Registered trade name for the altimeter setting window of a Kollsman altimeter. Sometimes erroneously used to describe the altimeter setting window of any altimeter.

Koroseal Plastic lacing used for support and anti-chafing protection of wires and lines.

Kraft paper Strong brown paper such as the material of which grocery sacks are made.

Kreuger flap A leading edge wing flap hinged at the bottom side of an airfoil. When it is actuated, the leading edge bends downward, increasing the overall wing camber and allowing the wing to develop additional lift at lower airspeeds.
