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 publication of the Federal Aviation Administration containing information on all airports, seaplane bases, and heliports open to the public. The A/F Directory contains communications data, navigational facilities, and certain special notices and procedures.
Industry:Aviation
A publication put out by the Department of Defense and used for flight planning, en route, and terminal operations.
Industry:Aviation
A published altitude representing the maximum usable altitude or flight level for an airspace structure or route segment. It is the highest altitude on a Federal airway, jet route, area navigation low or high route, or other direct route for which an MEA is designated in 14 CFR Part 95, at which adequate reception of navigation aid signals is assured.
Industry:Aviation
A published altitude representing the maximum usable altitude or flight level for an airspace structure or route segment. MAA is the highest altitude on a Federal airway, jet route, area navigation low or high route, or other direct route for which an MEA is designated in 14 CFR Part 95, at which adequate reception of navigation aid signals is assured.
Industry:Aviation
A published description of the flight paths aircraft must follow when approaching an airport for landing and when leaving the airport after taking off. All aircraft following the same flight pattern minimizes the danger of in-flight collision.
Industry:Aviation
A pulley in a belt-drive system used to adjust the tension on the belt that joins a drive pulley with a driven pulley. The idler pulley does not change the direction of rotation of either pulley, nor does it change the speed relationship between the pulleys.
Industry:Aviation
A pulse generator in a piece of electronic equipment used to synchronize the timing of switching circuits. In a digital computer, the clock determines the speed of the CPU.
Industry:Aviation
A pulse of electrical energy used to initiate an operation in certain types of electronic equipment.
Industry:Aviation
A pulse of high voltage produced across a coil when current flowing through it is interrupted. When direct current flows through a coil, a magnetic field surrounds each turn of wire, and this magnetic field is sustained as long as the current flows.
When the current is interrupted, the magnetic field instantly collapses, and the lines of magnetic flux cut across each turn of the coil. This collapsing field induces a short-duration pulse of voltage into the coil that is many times greater than the original voltage. This pulse of high voltage is called an inductive kick, or a transient voltage spike.
Industry:Aviation
A pulse-type electronic navigation system that shows the pilot, by an instrument-panel indication, the number of nautical miles between the aircraft and a ground station.
The DME transmitter in the aircraft transmits a specific pulse of electrical energy. This pulse is received by the ground station and retransmitted on another frequency. When the pulse is received back in the aircraft, the time used for its travel to the ground station and back is converted into terms of nautical miles to the station. DME is a portion of the military TACAN (Tactical Air Navigation) system.
