5.2.1 Visual presentation

The visual presentation replaces the OTW view of a conventional tower, with the purpose of providing a view of the aerodrome and its vicinity (i.e. area of responsibility). It may take different forms and designs depending on the specific technical solution. A common design used for implementation to date comprises a display that presents a wide field-of-view image (similar to the OTW view obtained from a conventional tower) derived from a central location on the aerodrome, typically a ‘camera tower’ comprising one or several cameras. This design is commonly known as a ‘panorama’ or ‘panoramic’ view. The ‘panorama’/‘panoramic’ view may also be supported by additional ‘hot spot/gap filler’ cameras (i.e. cameras situated in other locations around the aerodrome), as need be. Another design that has emerged is the so-called video wall view, where several sensors from various locations around the aerodrome are presented/stitched together in a combined view, hence presenting different view images from different locations around the aerodrome in a combined manner on this video wall. This set-up using a distributed camera system may e.g. be fit for use at larger multiple runway aerodromes, to support situational awareness also when distances are large.
