New possibilities of "A Duck Scheme" type wing-in-surface-effect aircraft used in armament sphere as well as ekranoplan used in transport, agricultural and industrial ones have been examined in the Article. Interest to use wing-in-surface-effect in the field of arms is connected with high aerodynamic quality, flight possibility at extremely small heights, take off and landing possibility on water. In article it is offered to use wing-in-surface-effect as low-level the rocket or the pilotless flying machine using extremely small height of flight for break of system of air defense at extremely small height with subsonic speed. Subsonic speed of rockets in a kind wing-in-surface-effect is advantage at its detection on the big removals from sensors of the ships. However at an exit on boundaries of direct visibility subsonic speed is a lack as the rocket on such removal with a high probability will be found out and destroyed. The given problem can be solved branch from the subsonic rocket of supersonic rockets at the approach on boundaries of probable detection. The peculiarities of construction of "A Duck Scheme" type ekranoplan improving its selfstabilizing characteristics during wind gusts influence have been also examined here. In the conditions of absence of small aircraft in agriculture use radio-controlled экранопланов is offered. It can be application of fertilizers, struggle against insects-parasites spraying from air. The offered complex can be used not only in agriculture. It can be a complex of tracking a condition of oil pipelines or gas pipelines, other highways with the only stipulation - flight should pass at small height over a basic surface. Realization of the big aerodynamic quality at the expense of use of screen effect is possible at the expense of the decision of a problem of longitudinal stability ekranoplan (wing-in-surface-effect) the aerodynamic scheme of "weft" at which losses on stabilization are absent. The described lobbies horizontal plumage of the special form allow to parry such ekranoplan counter wind indignations. Article contains the description of useful effects, conditions of their occurrence. In article on the basis of model of longitudinal static stability parities of parameters of a design for экранолета and for экраноплана which will allow them to provide properties of stabilization in a wide range of wind impulses and flight heights are defined. The algorithm of calculation of these parameters ekranoplan which gives the chance designing such ekranoplan is resulted.
