The control tower is, if only by its height, the most characteristic building on an airfield. It is easily recognizable, even if it is integrated into a service area or the terminal building.
The structure and function of this building gives it the look of the sceptre of the airport.
It is both a "nerve centre" and the "eye" of the airport.
Its image is also representative of the technical progress which has enabled the sky to be conquered. Does the control tower cabin not in fact, represent the entity governing aerial movement, landings, take-offs, ie, the work of the airport?
The presence of the control tower also has a symbolic role: it reassures users, who have a link between the aeroplane and the ground before their very eyes.
It is from the control tower cabin that the airfield is controlled. All equipment necessary for control of the airfield is linked to equipment located in the control tower cabin and the service area. It has become normal to give the general name of control tower to the shaft and the control tower cabin, or the control tower cabin alone when this is more or less linked to its support building
