Assessment of the Flight Quality in Vertical Plane

Abstract

This article discusses the problem of the quality assessing of the crew An-148 piloting technique, taking into account the human factor. The calculations showed that the statistical distribution of the pitch angle does not contradict the normal distribution. It is known that the normal law of the distribution of parameters indicates a good quality piloting technique. An analysis of autocorrelation functions and its spectrum is proposed to quickly solve this problem. The assessment of the quality of the piloting technique by analyzing the autocorrelation function of the pitch angle and its spectrum is consistent with the estimation method according to the distribution laws. A good technique was established for piloting the An-148 pilot under normal piloting technique. It also offers a scheme of a warning system for failures of systems for displaying the values of the angle of attack or speed and an algorithm of actions in such cases.

Improving the Methods of Assessing the Quality of Aircrew Piloting Technique

“…Next, we group the data according to the value of y amp and compile a table as y amp increases (Table I). In the next step, we calculate the spectrum of the unnormalized autocorrelation function with the smallest exponent y amp and compare it with the large exponents [5].…”
