Aircraft recognition generally depends on learning the external appearance of the aircraft, both friendly and hostile, most likely to be encountered. Techniques used to teach this information have included scale models , printed silhouette charts, slide projectors , computer aided instruction and even specially-printed playing cards .
The encoded number changes day-to-day. When the number is received and decoded in the aircraft transponder, a further cryptographic encoding is applied. If the result of that operation matches the value dialled into the IFF in the aircraft, the transponder replies with a Mode 3 response as before. If the values do not match, it does not respond.
Avionics software is embedded software with legally mandated ... Most modern commercial aircraft with auto-pilots use flight computers and so called flight management ...
Automatic target recognition (ATR) is the ability for an algorithm or device to recognize targets or other objects based on data obtained from sensors. Target recognition was initially done by using an audible representation of the received signal, where a trained operator who would decipher that sound to classify the target illuminated by the ...
A Royal Air Force Boeing E-3 Sentry over North Yorkshire. An airborne early warning and control (AEW&C) system is an airborne radar early warning system designed to detect aircraft, ships, vehicles, missiles and other incoming projectiles at long ranges, as well as performing command and control of the battlespace in aerial engagements by informing and directing friendly fighter and attack ...
This is a list of aircraft used by the United States Air Force and its predecessor organizations for combat aerial reconnaissance and aerial mapping. The first aircraft acquired by the Aeronautical Division, U.S. Signal Corps were not fighters or bombers but reconnaissance aircraft. From the first days of World War I, the airplane demonstrated ...
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). [1]
Warren built a prototype FDR called "The ARL Flight Memory Unit" in 1956, [9] and in 1958 he built the first combined FDR/CVR prototype. [8] [10] It was designed with civilian aircraft in mind, explicitly for post-crash examination purposes. [11]
