Abstract: An automatic computer-aided detection (CAD) system is proposed to assist aircraft pilots to find safe emergency landing sites where no runway is available. Customarily, pilots are prepared to distinguish safe landing destinations by looking to the ground with crude eyes. Be that as it may, human vision can be altogether influenced by climate conditions. Additionally the significant choice extraordinarily relies on upon the pilot's flight experience. Moreover, the pilot will be under the enormous weight in such to great degree critical circumstances. Time is another essential variable of the survival of travelers and the pilot himself. In this manner, a powerful, solid and productive calculation of selecting hopeful landing destinations is emphatically coveted. By applying picture preparing and investigation methods we proposed a programmed CAD framework and preparatory results demonstrate the attainability of the proposed calculation. The principle commitment of this framework is the configuration of a completely programmed CAD calculation for deciding safe crisis landing locales. Above all else, we explored the fitting criteria to evaluate landing destinations. Two geographic ideas, height and landform, are contemplated. The angle of rise by and large decides the unpleasantness of the landscape. Landform depicts territory covering, i.e., backwoods, grass, water, rock, structures, and so on. Smooth rise inclination without anyone else's input is not adequate to ensure a sheltered landing site, subsequent to the related landform could be unpleasant. Also, the arrival site needs to have adequate length and width which can shift with the sort of plane to empower safe crisis landing.
