About TCAS which helps planes from colliding each other in the air
This time, let’s see what helps prevent planes from colliding with each other in the air.
September 25, 1978 Southwest Airlines flight no. The 182 collided with a Cessna small plane and crashed at San Diego Airport. 144 passengers were killed.
Following the tragedy, the FAA (Faderal Aviation Admistration) devised a system to prevent aircraft from colliding with each other in the air.
This system is called TCAS (Traffic Alert and Collision Avoidance System). It sounds like Tee Cass.
Before the system could be widely used, another tragedy occurred in 1986 when Aeromexico Airlines DC-9 collided with a four-seater Piper Archer aircraft at Cerritos Airport in California. Following the deaths of 82 people, the FAA ordered the installation of all TCAS aircraft flying over US airspace.
Other countries soon followed suit. The first commercial aircraft was assembled in 1990, and all American commercial aircraft were completed in 1993.
Here is what you know about TCAS.
TCAS is a system that constantly interrogates other aircraft to prevent collisions between aircraft. It detects the signal emitted by the transponders of another aircraft and alerts the pilot.
The TCAS antenna is mounted one at the bottom of the aircraft and one at the top.
In other words, the distance is calculated by radar when the interrogate signal is transmitted to another aircraft and the 4-digit and altitude transmitted by the aircraft’s transponder is captured. Shape color-based color warning; The dashboard alerts you to notice the audio alloys.
It is given different names depending on the distance between the other aircraft and your own aircraft. These include a 20-mile-wide surveillance range or other advisory range, and a 3.3-mile-wide traffic issuance or traffic-advisory range within 2.3 miles of your aircraft.
The pilot alerts the pilot as soon as the machine detects an intruder entering this range. The pilot can also avoid collisions with each other by diverting his aircraft according to the instructions of the engine, especially in the resolution advisory range.
The transponder in the machine detects all aircraft entering the specified distance as soon as it starts operating in the air. The machine calculates the altitude with the 4 digit code captured by nearby aircraft.
The dashboard then shows the location and altitude of all aircraft around the aircraft. The display panels vary depending on the manufacturer.
As an audible signal:
– Climb Climb
– Desend Desend
– Increased climb increased climb
– Level off level off
The pilot is alerted. The pilot then shuts off the auto pilot and manually adjusts the altitude of the aircraft to avoid mid-air collisions.
In modern systems, better methods can be used. TECAS 1, TCAS 2, TCAS 3 and so on.
