Aircraft and piloting assistance method for landing in degraded visibility conditions

A piloting assistance method for landing an aircraft on a target zone centered on a touchdown point,

• wherein the method comprises an assistance phase comprising determining (STP1), using an on-board computer, a recommended angle (theta) configured to assist a pilot in converging towards a predetermined target speed (vp) with the aircraft, the recommended angle (theta) being a pitch attitude angle, the recommended angle (theta) being determined using a calculation law as a function of the target speed (vp) and of an estimated current aerodynamic drag (fx), the assistance phase comprising displaying (STP2), on a display and with respect to an angle-graduated scale, a first assistance symbol bearing the recommended angle (theta) and a second assistance symbol bearing a current angle (angcur).
