Keywords: aircraft operational management, state-estimation

The technical state of a system changes randomly during its operation. It can be determined by so called internal system parameters. Therefore the momentary technical state of the system can be described mathematically as a point of the multidimensional state space defined by its internal parameters. The main goals of the technical diagnostics are the determination of momentary location of the examined system and to forecast direction and velocity of its movement in the abovementioned state space. Knowing momentary technical state and its changing, you can decide the most optimal operational strategy and forecast the needed service work. This paper will show the mathematical diagnostic modeling and its possibility of use of state-estimation based on mathematical modeling for the operational management by case of pneumatic brake system of the helicopter MI -8 HIP.
