Why do Aerodrome Controllers have large windows with a downwards angle?

Aerodrome Controllers have large windows with a downwards angle primarily to provide them with an unobstructed view of the entire airfield. This design allows controllers to visually monitor all aspects of the aircraft operations, including takeoffs, landings, and taxiing. By having panoramic visibility, they can effectively manage air traffic and coordinate movements on the ground, ensuring safety and efficiency in operations.

The downwards angle of the windows helps in reducing any visual obstructions that could block the controller's line of sight. It also aids in reducing sun glare, which could impair vision and situational awareness. However, the primary focus remains on the ability to maintain constant visual contact with the aircraft and ground vehicles operating in and around the aerodrome.

The design of the windows does not address sound reception significantly nor does it primarily serve to enhance ventilation, which are considerations that may have their own merits but do not closely relate to the necessity for effective visual control of the airfield.
