A squawker is a type of air traffic controller used by commercial airliners. It has a display that shows the location of the aircraft. The display shows the position of the aircraft and if it is in range to receive radio frequency data from the satellite.
A squawker is able to communicate with the control tower of the airfield. Most squawkers are wireless and can be located in an area such as a control tower or an airport.
A transponder is a small electronic device that generates a specific response when it receives an electromagnetic signal from a radio-frequency probe. Commercial airline aircraft have transponders on board to help in identifying them during air traffic management Squawkia.com. In aviation, a squawk is used primarily for communication between the control tower and the control room.
Some squawkers are also used by pilots to communicate with other pilots over a common system of radio frequencies known as Digital Control (DAC). Aircraft may also have squawkers mounted on the outside of the fuselage as well as in the engine compartment for the same purpose.
Some research has shown that squawking is best for non-flight critical situations such as initial take-off, in-flight landing, and emergency landing scenarios. However, there have been some questions as to the accuracy of some early flight-critical conditions. In any case, most of today’s squawking systems incorporate sufficient warning cues for aircraft as to the state of their engines and the direction they need to fly in to reach their destination.
Modern air traffic controllers often carry additional data sources such as radars and satellite communications and can instantly identify any problems with the aircraft’s performance. As new technologies and applications are developed, the scope of squawking will broaden and become more widespread in the aviation industry.
