Coordinates control air flights

The Speed of cars on the road can be monitored using 35Q DID
traffic lights and cameras. Unlike cars, airplanes in flight are
difficult to track and monitor. There are no traffic lights in
air space. How do air traffic controllers manage the planes 200..^
from their control towers? How do they inform the pilots
when they are safe to take off or land? In real life, air traffic
is managed and regulated using coordinate geometry.
An air traffic controller tracks the location of every aircraft jP
at any particular moment in time using coordinates. Every
aircraft's movement updates the coordinates in the system.
The coordinate system is one of the most important tools in
airtransport.
