show an idea of "topological structures plus number theory" for designing new-type GPWs
(abbreviated as Topsnut-GPWs, [8-10]).
Required all air carrier aircraft to be equipped with GPWS
by December 1975.
Synthetic vision is an integrated solution and will rely on traditional subsystems similar to traffic alert collision avoidance (TCAS), ground proximity warning system (GPWS
), flight management system (FMS) and displays to provide warning functions.
There was no planning for an enhanced GPWS
, and little management faith in or support for "growing" the program.
While the overall rate of aviation accidents has declined dramatically over the last 30 years, little improvement has been seen over the last 15 years despite the continued evolution and improvement of automated cockpit systems such as the Ground Proximity Warning System (GPWS
) and Traffic Collision Avoidance System (TCAS).
A requirement from the Australian Civil Aviation Safety Authority (CASA) that all aircraft be equipped with a Ground Proximity Warning System (GPWS
) has raised concerns that airfares will increase.
A related phenomenon has been noted in aviation automation, where it has been suggested that cockpit automation, such as Ground Proximity Warning Systems (GPWS
), by removing humans from the information processing loop, may diminish situation awareness by the flight crew and thereby fail to achieve the intended goal of reducing the danger of Controlled Flight Into Terrain (CFIT) (von Thaden, 2000).
Despite a standard onboard alert system known as the Ground Proximity Warning System (GPWS
), commercial airplane pilots fly into mountains with alarming regularity.
The warnings came from the plane's Ground Proximity Warning System (GPWS
), a device containing a computer-generated voice linked to a radar that is automatically activated when the plane gets dangerously close to the ground or to a natural obstruction while in flight, said an unnamed official.
Its predecessor, GPWS
, looked down but not ahead, has been in use in the U.S.
Early designs of some automated alerting systems, such as the Ground Proximity Warning System (GPWS
), were not trusted by pilots because of their propensity for false alarms.
Consider the example of the Ground Proximity Warning System (GPWS
), recently recounted by Jeff Brazil in the Los Angeles Times.
