An emergency drop system allows ballasted advertising banner (14) if disconnected from an aircraft to descend slowly to the ground. Banner (14) is suspended below an aircraft by line (4) held taut by ballasted container (24). Static line (26) attached to the aircraft will, on release of loop (6) of line (4) from the aircraft, pull on closures (12) and release parachute (8) from its container (10). Drag of parachute (8) in the slipstream will slow the fall of banner (14) and also pull on lanyard (20) so that it activates 3-ring release (22) causing container (24) to invert and disperse the ballast.

L'invention concerne un système de largage d'urgence permettant à des banderoles (14) publicitaires lestées de descendre lentement vers le sol, une fois déconnectées de l'avion. Une banderole (14) est suspendue sous un avion à un câble (4) tenu tendu par un conteneur (24) lesté. Le cordeau (26) d'amarrage fixé à l'avion, une fois la boucle (6) du câble (4) détachée de l'avion, engage des fermetures (12) et libère le parachute (8) de son conteneur (10). Le dragage du parachute (8) dans le sillage de l'air ralentit la chute de la banderole (14) et engage une longe (20) de telle sorte qu'elle active le largueur à trois anneaux (22), faisant ainsi se retourner le conteneur (24) qui libère alors son lest.
