Methods for Assessing the Glissade Entrance Quality by the Crew

Autocorrelation Functions and Their Use in Assessing Quality of The Approach

The correlation functions between information about the flight trajectory and distortions during the operator tracking operations considered below. This happens due to its psycho-physiological features in a state of high tension.

A comprehensive analysis of the trajectory of the aircraft allows to determine the degree of operator training, his psycho-physiological state, the quality of work of all elements of the aircraft, as well as the reliability of communication in the reception and transmission of commands.

The ideal trajectory control system is the one that provides for the full ergatic compatibility of the operator – aircraft subsystem and continuously processes information about the flight trajectory of the aircraft (AC) without errors and fully performs the specified flight program according to function I (t). In this case, the specified trajectory and information about the real flight trajectory will be the same. Any deviation from a given flight mode is immediately recorded by the onboard equipment, which also notifies the operator. If necessary, the operator can work this difference to zero (Figure 1).

Ideal system

If there is a following situation: the operator uses information I (t), which becomes a subject of distortion due to a combination of certain reasons. In this case, the information management facility will change and become different –I '(t) (Figure 2)
