Development of conceptual model of system of processing of the flight information

The error of definition of take-off weight by processing of onboard recorder data using the working techniques does not exceed 4 %, that by the conclusion of certified committee of the Scince-Resiarching Institute of Sivil Aviation it is acceptable. Excess of the take-off weight menacing to safety of flights becomes obvious at such accuracy. But more exact data on weight and draft of engines are necessary for flight. It is possible to count a mistake of length of start calculation of less then 2000 m. For definition of weight with accuracy of 2 and less percents draft should be known with same accuracy or higher.
