The invention relates to a device and a method for supplying informatics to pilots, especially in poor visibility, about, for instance, the borders of a runway (1). Along the long sides of the runway and at its beginning and end, signal means (2, 5) are arranged, which are translucent to e.g. UV radiation and which comprise a fluorescent material which converts the radiation penetrated by illumination into visible light. In the daytime, the UV radiation originates from sunlight. The converted light will then reinforce the usual light from the signal means, which originates from the sun's illumination thereof with visible light. As a result, in will be much easier to observe the signal means especially against the light. It is further suggested according to the invention that at night the signal means are illuminated by UV searchlights (34, 35). By a great number of signal means being illuminated simultaneously by a small number of searchlights, a great amount of electric equipment and installation work can be avoided. It is suggested that the signal means be made as flat screens in the form of square or rectangular pieces of plastic sheeting expanded between poles.
L'invention concerne un dispositif et un procédé permettant de fournir des informations aux pilotes, notamment par mauvaise visibilité, par exemple pour repérer les bordures de piste (1). On dispose sur les longs côtés de la piste ainsi qu'en début et bout de piste, des moyens de signalisation (2, 5) translucides aux rayons ultraviolets, entre autres, comprenant un matériau fluorescent qui transforme en lumière visible le rayonnement reçu par illumination. Durant la journée, les rayons ultraviolets proviennent du soleil, et la lumière convertie renforce alors la lumière habituellement émise par ces moyens de signalisation, qui résulte de l'illumination solaire en lumière visible. Il est donc beaucoup plus facile de voir les moyens de signalisation, surtout à contre-jour. Par ailleurs, la nuit, il est proposé d'illuminer lesdits moyens de signalisation via des projecteurs à ultraviolets (34, 35). En illuminant un grand nombre de moyens de signalisation simultanément par un petit nombre de projecteurs, il est possible de réduire considérablement la quantité d'équipements électriques et les travaux d'installation. Aux fins de l'invention, il est suggéré d'utiliser pour les moyens de signalisation considérés des écrans plats sous forme de pièces carrées ou rectangulaires de matière plastique en feuille tendues entre deux poteaux.
