The invention relates to a leading edge mobile flap () for a main wing of an aircraft, this flap including an aerodynamic skin () that has a bird impact-sensitive frontal area (), and a rear skin () integral with the aerodynamic skin (), the flap also comprising a plurality of ribs () spaced out along a leading edge longitudinal direction (X'). According to the invention, the flap additionally includes, between two directly consecutive ribs, a single rigid bird trajectory-deflecting wall () anchored to the skins (). Furthermore, in a cross-section taken along any plane orthogonal to the direction (X&#x2032;), the wall () forms with a geometric chord () of the flap an angle (&#x3b1;) with a value of less than 45&#xb0;.
