Reliability as complex indicator of system operation quality, in dependence on system basic purpose and conditions of exploitation process, involves different system characteristics. Regarding to the specific operational requirements of aircraft, mainly related to the flight safety, one of primary attributes of their reliability is failure-free performance. In this paper by considering the stationary conditions characteristics of renewal process estimation of probability for failure-free operation during a given flight time is done, and by analysis of reliability function, lower and upper limits of probability for failure-free operation are established. Thereby possibility for practical application of exponential distribution for failure-free performance consideration is shown, and method of aircraft reliability indicators determination is represented.

The paper analyzes a program for simulating the flight control of an antiship missile with the radar seeker. The paper analyzes a mathematic missile model an autopilot model and a target model. Thus obtained results enable a more realistic process of flight tracking of a particular antiship missile as the missile guidance along the whole trajectory provides many advantages over unguided projectiles, primarily because of the possibility to fire at moving targets. The flight control simulation model enables further study of this missile class.

Optical wavelength division multiplexing (WDM3) networking technology has been identified as a suitable candidate for future wide area network (WAN4) environments, due to its potential ability to meet rising demands of high bandwidth and low latency communication. Networking protocols and algorithms are being developed to meet the changing operational requirements in future optical WANs (OWAN).

To drive the vehicle on a straight line road can be put as a special case analysis of a Driver-Vehicle-Environment dynamical system, because longitudinal vehicle motion means that active driver participates in the conditions defined by road and vehicle parameters. In contemporary literature, there are some attempts of modeling the mentioned system in the case of a straight line drive, but, so far, there is no generally accepted model of a driver. It should be mentioned that the problem is more complex with fact that a very complex motor and transmission behavior must be assumed in dynamic conditions. There are some attempts of modeling the driver and vehicle in the case of straight line driving, with a goal of tracking the given, frequently variable vehicle speed.
