primary airport''s control tower.
A control tower, as the name suggests, is an air traffic control tower in more specific terms. Located in airports, a control tower is the connection between the pilot of the plane and the airport staff. Control towers are usually high above ground and have windows that are tilted out all around the room so that they can get a clear view of the planes in the airport in order to direct them around. Without the control tower, airport staff would not be able to send signals to the pilots and the airport will not be able to function at all as the planes would not know when and where to take off and land, park, move around and so on.
four main areas are terminal building airport information systems flight planning and control and control tower
You may be able to tour an air traffic control tower. You will need to contact the airport and ask if they allow tours.
