The present invention relates to an aircraft (1) having a sling (3) fastened to a fastening point (9), a local transverse vertical plane (P1) containing said fastening point (9) being parallel to a yaw axis (AX1) and to a pitch axis (AX2), a local longitudinal vertical plane (P2) containing said fastening point (9) being parallel to a yaw axis (AX1) and to a roll axis (AX3), said local longitudinal and transverse vertical planes (P2 and P1) intersecting at a vertical axis (AX4). The aircraft (1) is provided with a piloting assistance device (10) comprising firstly main determination means (20) for determining a first main angle (α1) between said vertical axis (AX4) and a first primary projection (3′) of said sling (3) on said local transverse vertical plane (P1) and a second main angle (α2) between said vertical axis (AX4) and a second primary projection (3″) of said sling (3) on said local longitudinal vertical plane (P2); and secondly display means (30) provided with a display screen (31) for quantitatively displaying said first and second main angles (α1,α2).
