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 ...
The certificate issued by the Federal Aviation Administration authorizing a person to perform certain aviation-related duties.
Airman certificates are issued to pilots, mechanics, and parachute riggers.
Industry:Aviation
The change in pressure and velocity of a supersonic flow of air as it passes over a surface, which drops away from the flow. As the surface drops away, the air tries to follow it. In changing its direction, the air speeds up to a higher supersonic velocity, and its static pressure decreases.
There is no change in the total amount of energy as the air passes through an expansion wave, and so there is no noise as there is when air passes through a shock wave.
“Expect (altitude) at (time) or (fix)” (air traffic control).
A portion of an instrument departure clearance, to provide a pilot with an altitude to be used in the event of two-way radio communication failure.
“Expect departure clearance (time)” (air traffic control). The time an operator can expect a gate release. This is used in the Fuel Advisory Departure (FAD) program.
“Expect further clearance (time)” (air traffic control). The time a pilot can expect to receive clearance beyond a clearance limit.
“Expect further clearances via (airways, routes, or fixes)” (air traffic control). This phrase is used by air traffic controllers to inform a pilot of the routing he may expect if any part of the route beyond a short range clearance limit differs from that filed.
“Expedite” (air traffic control). A warning used by air traffic controllers when prompt compliance is required in order to avoid the development of an imminent situation.
Industry:Aviation
The change in resistance of a potentiometer that varies directly with the number of degrees of rotation of the potentiometer shaft.
Industry:Aviation
The change in rotor blade velocity to compensate for a change in the distance between the center of mass of the rotor blade and the axis of rotation of the blade as the blades flap in flight.
Industry:Aviation
The change in the physical size of a material caused by the material absorbing heat. Thermal expansion causes a material to expand both in its length and in its volume.
Industry:Aviation
The change of a value, such as resistance, capacitance, or physical length, with temperature in such a way that the value increases as the temperature increases.
Industry:Aviation
The change of barometric pressure within a specified period of time. For aviation weather observations, the time period is normally three hours.
Industry:Aviation
The characteristic of a gyroscope that prevents its axis of rotation tilting as the earth rotates. This characteristic is used for attitude gyro instruments.
Industry:Aviation
The characteristic of a liquid that relates to its ability to vaporize, or change into a gas.
