ABSTRACT:
A foot board for an aircraft passenger door has an elongated nearly quadrilateral single piece construction with an inner and an outer longitudinal edge fastened by screw bolts to an aircraft door sill structure. The foot board is constructed as a one piece or integral milled component, extending over the entire width of the door sill, with an outward slope for drainage into a drainage collecting channel that receives any water from individual drainage channels feeding into the collecting channel running along the outer longitudinal edge of the foot board, and a rib is arranged between each of two neighboring drainage channels extending perpendicularly to the collecting channel. Each of the two ends of the collecting channel empties into a collecting basin having an outlet opening for collected liquids.
