A ground proximity warning system (GPWS) is a system designed to alert pilots if their aircraft is in immediate danger of flying into the ground or an obstacle. The United States Federal Aviation Administration (FAA) defines GPWS as a type of terrain awareness and warning system (TAWS). [1]
Bateman in 2012. Charles Donald Bateman (8 March 1932 - 21 May 2023 (aged 91)), often known as Don Bateman, was a Canadian electrical engineer and the inventor of the Ground Proximity Warning System (GPWS), a device that is responsible for a marked decline in controlled flight into terrain accidents, such as the Mount Erebus Disaster with Air New Zealand Flight 901.
GPWS was found to be superior in that it would warn only when necessary, provide maximum warning time with minimal unwanted alarms, and use command-type warnings. [6] Based on these reports and NTSB recommendations, in 1992 the FAA amended §135.153 to require GPWS equipment on all turbine-powered airplanes with ten or more passenger seats. [6 ...
TERPROM (terrain profile matching) is a military navigation Ground Proximity Warning System (GPWS) employed on aircraft and missiles, which uses stored digital elevation data combined with navigation system and radar altimeter inputs to compute the location of an aircraft or missile above the surface of the Earth. It is also used as a warning ...
At 12:49 pm, the ground proximity warning system (GPWS) began sounding a series of "whoop, whoop, pull up" alarms, warning that the plane was dangerously close to terrain. The CVR recorded the following: [ nb 2 ]
At 4:38 PM EST, LaGuardia ATCT stated, "You are cleared to land, Delta five fifty-four," and the first officer acknowledged the landing clearance. The CVR recorded the sound of the ground proximity warning system (GPWS) announcing minimums. About a second later, the captain stated that he had the approach lights in sight.
The U.S. FAA defines GPWS as a type of terrain awareness warning system.[1] More advanced systems, introduced in 1996,[2] are known as enhanced ground proximity warning system, although sometimes confusingly labeled with the TAWS term. I think this should be rephrased. As far as I know, the EGPWS is a TAWS. TAWS is the system, EGPWS is a ...
Seconds before impact, the ground proximity warning system (GPWS) activated, and sounded alarms warning the crew of the imminent collision with the mountains. First Officer Boonyayej warned Captain Suttimai and urged him to turn the aircraft around, but possibly due to his frustration from the communications with ATC, Suttimai erroneously ...
