Were no navigation aids to help pilots find their way. The Evolution of Airway Lights and Electronic Navigation It was installed in the late 1940s and early 1950s. Tower controllers issue landing and taxi clearance to get the aircraft to its parking position at the airport.The perfection of the Very-High-Frequency Omnidirectional Radio Range (VOR) airways made the four-course radio range obsolete. Low level or terminal air traffic controllers issue instructions to the pilot to line the airplane up with the runway so they are in the correct position to land. The air traffic controller ensures the plane has a safe separation distance from other aircraft approaching the airport. When a plane approaches its destination, high or low level controllers instruct the pilot on safe descent routes. As your plane passes from one to the other, or climbs into high level airspace, it is monitored on radar screens and control is passed from one controller to another. That same controller, or a teammate, will then give takeoff clearance when the runway and airspace are clear and it is safe to do so.Īs an aircraft travels over land or sea, and at various altitudes, the airplane may pass through different pieces of airspace. The chart below illustrates who is in control as you make your way from one airport to another.Īt an airport with a control tower, the pilot contacts a tower controller to obtain clearance to move from their gate to their assigned runway, via a specific path. Working in teams, each responsible for different areas of airspace, our air traffic controllers coordinate with various units across the country to ensure each plane is operating safely at each stage of flight. Our air traffic controllers use sophisticated systems and technology, often designed and developed by NAV CANADA employees, to track the location of aircraft and make decisions to ensure efficient flow of traffic. When you fly, our air traffic controllers are with you every step of the way. Air traffic controllers ensure aircraft maintain vertical, lateral or time separation, while following strictly defined rules, procedures and regulations. Our air traffic controllers instruct pilots to climb, turn, descend and move safely, whether they are on the ground at an airport or thousands of feet in the sky. They work with pilots operating all types of planes, from single-engine aircraft to large multi-engine jets. Managing 18 million square kilometres of Canadian and oceanic airspace, our air traffic controllers direct planes, either from the cab of a control tower or on a radar screen in an area control centre (ACC), 24 hours a day, 7 days a week.
