A double-curved aircraft door intended for an aircraft that extends along a longitudinal axis, this aircraft door having at least one locked configuration and one open configuration, this aircraft door including: - a leaf and a frame, the leaf being articulated relative to the frame; - locking means including leaf stops and frame stops, each leaf stop being positioned against a corresponding frame stop when the aircraft door is in its locked configuration, each leaf stop and its corresponding frame stop forming a pair of complementary stops that include bearing surfaces (26, 27) that are in contact in an area of contact when the aircraft door is in its locked configuration, said pairs of complementary stops being arranged on a first lateral edge and on a second lateral edge of the aircraft door, the corresponding areas of contact being arranged in at least two sets: a first set of contact areas of the first lateral edge and a second set of contact areas of the second lateral edge; wherein - the isobarycenter of each contact area of the first lateral edge is disposed in a first plane perpendicular, in a fitted state of the aircraft door, to said longitudinal axis; - the isobarycenter of each contact area of the second lateral edge is disposed in a second plane perpendicular, in the fitted state of the aircraft door, to said longitudinal axis; - for each contact area the normal to the contact area passing through its isobarycenter (31A, 31B) passes through the axis of a mean cylinder, the mean cylinder being defined as the circular base cylinder the axis of which is parallel, in the fitted state of the aircraft door, to said longitudinal axis and the radius of which satisfies the following condition: the sum of the distances (D1,D2,D3,D4,D5,D6) between the isobarycenter of each contact area of the first lateral edge and the mean cylinder is equal to the sum of the distances (d1,d2,d3,d4,d5,d6) between the isobarycenter of each contact area of the second lateral edge and the mean cylinder; - for each contact area the normal to the contact area passing through its isobarycenter (31A, 31B) forms a deviation angle with a plane (32, 33) perpendicular, in the fitted state of the aircraft door, to said longitudinal axis, the deviation angles of all the contact areas being equal. - a leaf and a frame, the leaf being articulated relative to the frame; - locking means including leaf stops and frame stops, each leaf stop being positioned against a corresponding frame stop when the aircraft door is in its locked configuration, each leaf stop and its corresponding frame stop forming a pair of complementary stops that include bearing surfaces (26, 27) that are in contact in an area of contact when the aircraft door is in its locked configuration, said pairs of complementary stops being arranged on a first lateral edge and on a second lateral edge of the aircraft door, the corresponding areas of contact being arranged in at least two sets: a first set of contact areas of the first lateral edge and a second set of contact areas of the second lateral edge; - the isobarycenter of each contact area of the first lateral edge is disposed in a first plane perpendicular, in a fitted state of the aircraft door, to said longitudinal axis; - the isobarycenter of each contact area of the second lateral edge is disposed in a second plane perpendicular, in the fitted state of the aircraft door, to said longitudinal axis; - for each contact area the normal to the contact area passing through its isobarycenter (31A, 31B) passes through the axis of a mean cylinder, the mean cylinder being defined as the circular base cylinder the axis of which is parallel, in the fitted state of the aircraft door, to said longitudinal axis and the radius of which satisfies the following condition: the sum of the distances (D1,D2,D3,D4,D5,D6) between the isobarycenter of each contact area of the first lateral edge and the mean cylinder is equal to the sum of the distances (d1,d2,d3,d4,d5,d6) between the isobarycenter of each contact area of the second lateral edge and the mean cylinder; - for each contact area the normal to the contact area passing through its isobarycenter (31A, 31B) forms a deviation angle with a plane (32, 33) perpendicular, in the fitted state of the aircraft door, to said longitudinal axis, the deviation angles of all the contact areas being equal.
