ICAO Doc 9830 defines A-SMGCS as follows: Advanced surface movement guidance and control system (A-SMGCS). A system providing routing, guidance and surveillance for the control of aircraft and vehicles in order to maintain the declared surface movement rate under all weather conditions within the aerodrome visibility operational level (AVOL) while maintaining the required level of safety.
For groundwater "potentiometric surface" is a synonym of "piezometric surface" which is an imaginary surface that defines the level to which water in a confined aquifer would rise were it completely pierced with wells. [1] If the potentiometric surface lies above the ground surface, a flowing artesian well results.
The Airport Movement Area Safety System (AMASS) visually and aurally prompts tower controllers to respond to situations which potentially compromise safety. AMASS is an add-on enhancement to the host Airport Surface Detection Equipment Model 3 ( ASDE-3 ) radar that provides automated aural alerts to potential runway incursions and other hazards.
In the United States, airport diagrams are published as part of Terminal Procedures Publication and are updated every 56 days unless there is a critical safety issue. [1] Commercial providers such as Jeppesen also published their own version of airport diagrams and can include additional airport details. [8]
Airport weather stations are automated sensor suites which are designed to serve aviation and meteorological operations, weather forecasting and climatology. Automated airport weather stations have become part of the backbone of weather observing in the United States and Canada and are becoming increasingly more prevalent worldwide due to their ...
After several high-profile accidents including Eastern Airlines 111 and the 1991 Los Angeles airport runway collision, the National Transportation Safety Board highlighted the need to find new technologies that could address the issue. In 1991, the NTSB issued a formal safety recommendation that the directed the FAA to develop "an alternate ...
A typical runway safety area, marked in brown color. A runway safety area (RSA) or runway end safety area (RESA, if at the end of the runway) is defined as "the surface surrounding the runway prepared or suitable for reducing the risk of damage to airplanes in the event of an undershoot, [1] overshoot, or excursion from the runway."
The FAA's design criteria for new airports designate Runway Safety Areas (RSAs) to increase the margin of safety if an overrun occurs and to provide additional access room for response vehicles. A United States federal law required that the length of RSAs in airports was to be 1,000 feet (300 m) by the end of 2015, in a response to a runway ...
