The Runway Awareness and Advisory System (RAAS) is an electronic detection system that notifies aircraft flight crews on the ground of their position relative to their allocated runway. It is a type of Runway Situation Awareness Tool (RSAT).
The civilian aircraft frequency for voice distress alerting is 121.5 MHz. Military aircraft use 243 MHz (which is a harmonic of 121.5 MHz, and therefore civilian beacons transmit on this frequency as well). Aircraft can also signal an emergency by setting one of several special transponder codes, such as 7700.
Jeju Air initially said that the crashed aircraft was not involved in any prior incident, but data from the Korea Airports Corporation showed that in February 2021, the aircraft was damaged when its tail struck the runway during takeoff from Gimpo International Airport in Seoul, for which Jeju Air was fined 2.2 billion won ($1.5 million) by the ...
The system operates with ground and approach sensor systems to ascertain aircraft locations in approaching and ground movement situations. It uses airport radars, state-of-the-art signal processing, and advanced computer technology to improve airport safety. In this program, 40 systems were to be delivered to the Federal Aviation Administration.
On 25 September 1979 a light aircraft 'G-BGHR' left at 1pm from Stansted airport; it descended from 31,000ft to 12,000ft, in an exercise at 2.36pm; it flew in circles, after the pilot became ill from hypoxia, and the plane began to make four-mile-wide circular paths for six hours, moving south, and crashed in a French vineyard at Le Tremblay at ...
NTSB investigators reported discovering critical controls on some Boeing 737s — including its MAX airplanes — could jam after discovering a part that could fail.
A voice warning system is a system designed to alert the crew of an aircraft to imminent safety hazards. It is often known as a Bitchin' Betty, a slang term used by some pilots and aircrew and submariners (mainly North American). The enunciating voice, in at least some aircraft systems, may be either male or female.
FLARM is a proprietary electronic system used to selectively alert pilots to potential collisions between aircraft. It is not formally an implementation of ADS-B, as it is optimized for the specific needs of light aircraft, not for long-range communication or ATC interaction. FLARM is a portmanteau of "flight" and "alarm".
