Understanding Aviation Radar

Air Radar/Ground Control Aviation

Ground Control is a set of air-controllers that pilots speak to so as to ensure safe landing or take off. Ground control is responsible for tracking air craft movement on the runaway. Prior to take off or landing, pilots are transferred to the Local Control (Tower). The Local Control ensures that there is a clear runaway for takeoff or landing procedure within a five mile radius in the airport.There is always a disciplined communication on the ground involving the Ground Control and Local Control to ensure safety on the ground.

Communication involves meticulous request and approval system. Supposing the plane is landing, the Ground Control team guides it through the gate after the Tower Control team has guided it from active runaways.The time taken by the plane to reach the gate depends on various factors. However, the primary factor is the number of planes ready for take off or heading towards the gate.The more the number of planes on the ground, the more time a plane takes to reach the gate. Additionally, the layout of the airport plays a major role in guiding planes on the ground. Airports that have straight taxiways make aircraft to reach higher taxing speed compared to those with more turns and less taxiways.

An aircraft that is airborne is normally transferred to the Approach Departure Control, responsible for monitoring aircraft that is 5 miles out to 50 miles from the airport using Airport Surveillance Radar.Just like other radar systems, airplane radar contains high frequency pulses transmitted in short phases.Radio waves from the radar are transmitted by magnetron,an equipment present in the system.

When an obstruction comes in the path of the transmitted pulses,it gets reflected to the radar system, thereby helping detect the object and how far is it from the aircraft.The air radar also comes in handy during bad weather conditions such as fog. Even though bad weather cannot obstruct radio waves, the device helps the operator to view planes in close proximity to avoid collision.
