The inventive aircraft with off-aerodrome landing consists of a body (1), a lifting wing (2) and the onboard part of a rope arresting and landing device comprising an arresting hook (5) which is provided with a grip (6). In the preferred embodiment, said aircraft is provided with a propeller (3) arranged in an annular empennage (4). Said arresting hook is arranged in such a way that it is rotatable around the transversal axis (8) of the aircraft situated in a longitudinal spacing of the aerodynamic mean chord of the wing. The aircraft leads for landing with the upwardly deployed arresting hook in such a way that the trajectory (12) of a top pickup point (6) is higher than the trajectory (13) of the highest top point of the aircraft and higher than a cable or rope (14) tensed on a landing area. The trajectory (13′) of the highest point of the aircraft located ahead of the arresting hook passes at a lower level than the cable (14). In said conditions, the grip of the arresting hook holds the cable which has a required effort for drawing it from a stationary arresting device. By overcoming said effort, the aircraft spends a flight kinetic energy and stops being suspended on the cable. |
