Understand the danger of personnel problems and GHS guidance, therefore, seek to engage in a program of experienced professionals from other post-Soviet OKB previously worked on passenger aircraft. But, having gathered together, these people were in a very difficult position. After all, in the Soviet Union there was no single school of creating planes, each company to use their decades Legacy methods of calculation, the principles of body-weight layout, time-tested "individual" design solutions. When it tried to shift in one pile, and even using the "methodical support of the" Boeing ", it turned out that the end result is virtually no one is sure. By the way, one of the reasons for the delay of the first flight "Superjet" (4 *) lies precisely in this: in fact on documents authorizing the plane for the first time up in the air, you need to put your personal signature ... Thank God, in Russia there are still TsAGI and SibNIIA almost completely taking over the design and testing of wing aerodynamics of the aircraft as a whole. In the laboratories of these famous institutions was carried out more than 4000 models of purging SSJ-100, which gives reason to concern with due regard to the declared characteristics of the liner and hope for an acceptable degree of its safety.
