How many Terminal Surveillance Radars (TSRs) are present in Canada?

The correct choice indicates that Canada has 27 Terminal Surveillance Radars (TSRs). TSRs play a critical role in air traffic management as they provide real-time information on the position of aircraft in the terminal airspace, which includes the area around airports. Unlike en-route radars that monitor aircraft over long distances, terminal radars focus more closely on the approaches and departures from airports, ensuring safety and efficient handling of air traffic in busy areas.

Canada has a network of 27 TSRs strategically placed to cover major airports and busy air traffic sectors. This extensive coverage is essential for managing the high volume of traffic in Canadian airspace, especially during peak flying hours. Each radar facility contributes to enhancing situational awareness for air traffic controllers, helping them ensure that aircraft maintain safe distances from one another while landing and taking off.

The number 27 reflects a comprehensive approach to aviation safety in Canada, fulfilling both regulatory requirements and operational needs across the vast geographical landscape of the country.
