Due to fuel consumption by flight conditions, typical helicopter configurations have nonstationary pitch, roll, and yaw moments, forces, and stresses distributions. For such analysis, test data scatter, and many other typical problems, traditional mathematics has no concepts and methods adequate and general enough. This holds for the real numbers, sets, cardinalities, measures, probabilities, absolute and relative errors, as well as for the least square method, reliability, and risk estimations. There is no possibility to invariantly estimate the contradictoriness of a problem and the confidence in the exactness of an exact solution. The last concept also needs certain generalizations along with separation methods. Elastic mathematics provides many general concepts and methods fully adequate and very effective by estimating approximation quality, exactness confidence, reliability, and risk. All the obtained results apply to predicting the gravity center movement and the fatigue strengths of responsible structural elements, e.g., in aircraft building.
