A landing made in a direction across, or nearly perpendicular to, the direction from which the wind is blowing.
Industry:Aviation
A language, made up of zeros and ones, that is usable by a digital computer. Machine language is difficult to write into a computer, so compilers and assemblers are used. A compiler is a special program that converts a high-level language that is easy for a programmer to use, into machine language that can be used by the computer. An assembler converts assembly language programs into machine language the computer can use.
Industry:Aviation
A lapse rate greater than the dry-adiabatic lapse rate, greater than 3°F per thousand feet.
Industry:Aviation
A large bending tool used to make straight bends across a sheet of metal. The metal to be bent is clamped between a flat lower jaw and an upper jaw fitted with a radius bar having the proper bend radius.
A heavy leaf, mounted on a hinge, folds up to bend the metal over the radius bar. A leaf brake is also called a cornice brake.
Industry:Aviation
A large block of metal that was molded as it was poured from the furnace. Ingots are further processed into sheets, bars, tubes, or structural beams.
Industry:Aviation
A large metalworking machine that uses heavy matched dies to form compound curves in sheet metal.
The sheet of metal to be formed is placed over a female die, and a heavy, matching male die is raised above it and dropped into the female die, forming the metal into the shape of the dies. Drop hammers are also used to forge semimolten metal in a die.
Industry:Aviation
A large piece of heavy, waterproof canvas, fitted along its edges with eyelets. Ropes can be tied through the eyelets to hold the tarpaulin tight over whatever device it is protecting.
Industry:Aviation
A large resistor in the ground circuit of a heavy-duty aircraft generator through which all of the generator output current flows. The voltage drop across this resistor is used to produce the current in the paralleling circuit that forces the generators to share the electrical load equally.
Industry:Aviation
A large shear used to make straight cuts across a sheet of metal. Squaring shears used for light-gage steel and thin aluminum alloy sheets are operated by a foot pedal, and shears used to cut heavy plate steel are operated by energy stored in a large flywheel by a small electric motor.
Industry:Aviation
A large shop tool used to make straight bends across a sheet of metal. The sheet of metal is clamped in the brake, and a heavy steel leaf is lifted to bend the metal. The distance between the clamping jaw and the hinge line of the leaf determines the radius of the bend. Cornice brakes are often called leaf brakes.
