Structures, systems and methods provide a load-bearing aircraft flooring within an aircraft's fuselage. Load-supporting aircraft flooring systems preferably are provided with a longitudinally separated series of transverse bridges having an upper doubler flange which defines latitudinally separated upper openings, and a latitudinally separated series of beams which include an upper flange and a pair of separated depending web flanges received within respective upper openings of transverse bridges. The upper flanges and web flanges of the beams may thus be connected to the transverse bridges. The transverse bridges may include latitudinally separated Y-shaped supports which define the upper openings thereof. According to certain embodiments, the Y-shaped supports include an upper fork region and a lower support post region. The beams may include opposed bridge fixation fingers protruding outwardly from the upper flange of the beam for joining the beams to a respective underlying one of the transverse bridges. Aircraft flooring panels may thus be connected to the beams, preferably by means of flooring fixation fingers protruding outwardly from the upper flange of the beams. Seat tracks for attaching aircraft seats and/or other interior aircraft structures/monuments are preferably fixed to the upper flanges of the beams coincident with its longitudinal axis.
