Aviation Supplies & Academics, Inc. (ASA) develops and markets aviation supplies, software, and books for pilots, flight instructors, flight engineers, airline professionals, air traffic controllers, flight attendants, aviation technicians and enthusiasts. Established in 1947, ASA also provides ...
A semisolid lubricant made by mixing oil with calcium carbonate. Lime grease is more suitable for use around water than grease having a sodium carbonate base.
Industry:Aviation
A semisolid lubricant made of lithium salts and fatty acids. Lithium grease is highly water resistant and is useful for low-temperature lubricating applications.
Industry:Aviation
A sensitive electronic device used to detect and display alpha waves from the human brain.
Industry:Aviation
A sensitive instrument that measures the amount of force exerted on an object because of its acceleration. Accelerometers are calibrated in G-units (Gravity units). One G-unit is a force equal to the weight of the object.
Industry:Aviation
A separation of the layers of a laminated material. Plywood is made up of layers, or laminations, of wood glued together. When the glue weakens, the layers can separate and the plywood is said to be delaminated.
Delamination of bonded composite materials causes the materials to lose strength.
“Delay indefinite (reason, if known) expect further clearance (time)” (air traffic control). A phrase used by ATC to inform a pilot when an accurate estimate of the delay time and the reason for the delay cannot immediately be determined. Such delays could be a disabled aircraft on the runway, terminal or center area saturation, or weather below landing minimums.
Industry:Aviation
A series of alphanumeric characters that may be formed by segments made visible, usually by light-emitting diodes (LED) or liquid crystal displays (LCD). The segments are selected by a dedicated digital computer to form the appropriate character.
The most widely used numerical display is made of seven segments arranged to form the numeral eight (8). By selectively energizing two or more segments, any numeral between zero (0) and nine (9) may be formed.
Industry:Aviation
A series of baffles, or partitions, inside an aircraft fuel tank. These baffles have holes in them that allow the fuel to feed to the tank outlet, but prevent the fuel from surging enough to uncover the outlet.
Aircraft fuel tanks carry such large quantities of fuel that the sloshing (surging back and forth) of the fuel in a partially full tank could cause severe control problems.
Industry:Aviation
A series of circular cracks in the dope film on a fabric-covered aircraft. Ringworms appear when a blunt object presses against the fabric that is covered with a dope film that has become brittle because its plasticizers have dried out. Ringworms can be removed by rejuvenating the dope.
Industry:Aviation
A series of circumferential grooves cut into the tread of a tire. A rib tread pattern provides superior traction and directional stability on hard-surfaced runways.
Industry:Aviation

: V2 — takeoff safety speed.
: V2min — minimum takeoff safety speed.
