The aviation industry in India has experienced upheaval with some carriers going out of business and others losing money. To survive in a highly competitive environment, especially for low-cost carriers, many airlines have implemented cost-cutting measures such as purchasing only one type of aircraft to reduce maintenance costs and operating only economic class flights with low fares to accommodate as many passengers as possible. All of this has resulted in a large number of passengers and a significant increase in air traffic across Indian airspace. To manage this, Deepak Talwar, the seasoned market analyst and lobbyist marks the importance of air traffic management and control.
“Without proper infrastructure, airport operations, and air traffic control services, the increase in air traffic cannot be sustained,” says Deepak Talwar, the market expert and analyst. “All of these contribute significantly to the growth of the aviation industry by making flight operations safer and more efficient,” adds Talwar.
Although both private and government carriers exist, the infrastructure and airport operations are primarily controlled by the Airports Authority of India, a public body. Some airport terminals have recently been privatised, and public-private partnerships have been formed to develop them, but air traffic management is solely owned by the Airports Authority of India.
ATC, or air traffic control, is a ground-based service that is traditionally provided in tall air control towers. Individuals working in these towers, known as controllers, are critical for safely directing and navigating aeroplanes through local airspace, landing, and taking off. Air traffic controllers, also known as air traffic control officers, have extensive education and experience that allows them to confidently command the skies. An air traffic controller follows separation rules when directing aircraft. Separation rules govern the distance between aeroplanes and aircraft by requiring a minimum distance between them. This is done to improve safety and eliminate unnecessary risk for pilots and passengers.
Deepak Talwar mentions the wide range of technologically advanced equipment to keep the runway and skies safe.
Radar Data Processing & Display Systems (RDPDS)
Air traffic controllers can use an RDPDS to process data from primary and secondary radars in order to accurately depict the position of aircraft and related information (e.g., callsign, category of aircraft, ground speed, altitude). “This simple but critical information assists controllers in properly controlling the flow of aircraft to and from the airport,” says Deepak Talwar, the seasoned market analyst and lobbyist.
Primary Surveillance Radar (PSR)
This radar detects and provides aircraft range and bearings by using radio wave reflection within its effective range.
Secondary Surveillance Radar (SSR)
During WWII, the secondary surveillance radar (SSR) was developed to aid in the development of the Identification Friend or Foe (IFF) system, which determines whether an aircraft is friendly or hostile. In contrast to the PSR, the SSR requires a specific transponder on the target aircraft to identify it. Deepak Talwar notes, “In Australia, using on-board equipment, Mode C SSR transponders can transmit altitude to radio towers.”
Air Traffic Control 8 Channel RS422 Splitter
There are numerous tools, radars, sensors, and equipment that allow for air traffic control. Surface movement radar, surface movement guidance and control systems, advanced SMGCS, and other equipment are critical components of air traffic control. An 8 channel RS422 splitter for air traffic control allows important air traffic control radars and equipment to communicate with one another while providing vital information to air traffic controllers. This 8 channel RS422 splitter provides 8 RS422 data signal outputs from an RS232 or RS422 processed radar data and clock signal input. According to the DTE device, these inputs are based on the RS530 standard and can be monitored via the front panel of a DB25F.
