The Russian Air Force began to equip aircraft with a domestic collision prevention system instead of the American

In May 2021, it became known about the introduction in the aircraft of the Russian Air Force of a domestic air collision prevention system (SSAR), which replaced the American TCAS. The technology is used for flights in airspace in most countries of the world.

Now the introduction of our system on military aircraft is very active. SSP is located on IL-112 military transport aircraft, on IL-76MDM, IL-76MD-90A, IL-78 air refueling tank, on Tu-134. No foreign blocks will be needed, "said Sergey Baburov, First Deputy General Director of Navigator JSC (system developer), to TASS.

He explained that the domestic system, in the face of increasing sanctions by the United States, is a lifeline for Russian manufacturers of military and civilian aircraft, as well as for government customers.

Our system allows you to completely replace the product of the American manufacturer and carry out flights both in Russia and abroad, fully implementing the function of the defendant and the function of preventing collisions in the air of aircraft, "he said.

According to Baburov, by May 2021, most design bureaus and airlines complain that TCAS equipment with the TCAS-2 function fails or the manufacturer's warranty obligations end. Because of this, there is nothing to equip aircraft.

According to the Aviation Rules, the operation of aircraft not equipped with such a system is prohibited worldwide.^[1]

It is noted that the TCAS system has a number of limitations:

• TCAS can only give instructions on  vertical echeloning;
• The air traffic control system  does not receive instructions issued by TCAS to ships, so  air traffic controllers  may not be aware of such instructions, and even give contradictory instructions, which is the reason for the confusion of crews;
• For the efficient operation of TCAS, it is necessary that all aircraft be equipped with this system, since the aircraft detect each other from the responders.
