A system and method for making a decision of whether to carry additional fuel on an aircraft for a particular flight based on a forecast, such as for low visibility and ceiling. Preferably, observations-based probabilistic forecasts are utilized. The forecast probability of the weather at the planned aerodrome being below a prescribed minimum level is calculated using statistical regression analysis of past data. An optimal probability is estimated using cost parameters on an individual flight bases. If this forecast probability is greater than the optimal probability for a particular flight, then extra fuel is carried by that flight. This is in contrast to current practice whereby the same categorical forecast is applied to all flights. The combination of improved short-term forecasts and identification of optimal forecast probabilities minimizes the financial impact of errors and weather forecasts on airline operations thereby providing a superior financial outcome.

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.
