A defined path, consisting of one or more courses in a horizontal plane, which aircraft traverse over the surface of the earth.
Industry:Aviation
A defined rectangular area on a land airport prepared for the landing and takeoff run of aircraft along its length. Runways are normally numbered in relation to their magnetic direction rounded off to the nearest ten degrees, such as Runway 01 or Runway 25.
Industry:Aviation
A deformation, or physical change, in a material caused by a stress. According to Hooke’s law, the strain in a material, the amount it stretches or compresses, is directly proportional to the stress, until the elastic limit of the material is reached. Spring scales and certain types of torque wrenches work on the principle that strain is proportional to stress.
Industry:Aviation
A dense and horizontal roll-shaped cloud located on the lower leading edge of a cumulonimbus, or less often on a rapidly developing cumulus. Roll clouds indicate the presence of turbulence.
Industry:Aviation
A dense, airtight film formed on the surface of aluminum or magnesium alloy to prevent oxygen or electrolyte reaching the surface and causing oxidation or corrosion.
Industry:Aviation
A departure time restriction issued to a pilot by ATC (either directly or through an authorized relay) when necessary to separate a departing aircraft from other traffic.
Industry:Aviation
A depression (usually smooth) in the surface of a material caused by the part being struck or pressed on by some outside object. A dent, unlike a gouge, removes none of the material.
Industry:Aviation
A descending motion of the air in the atmosphere over a rather broad area.
Industry:Aviation
A design of compressor blade used in some of the modern axial-flow gas turbine engines. The leading edge is thicker than that of the conventional circular arc blade.
Controlled diffusion blades minimize transonic drag rise and prevent separation of the air over their surface. The thicker leading edges erode far less than the leading edges of circular arc blades.
Industry:Aviation
A designation of sky cover when part of the sky is hidden by surface-based obscuring phenomena.
