Automatic decision making process in a small unmanned airplane

In order to efficiently control passenger aircraft in general., the control process is usually adapted according to flight situations. A system for selection of a particular flight situation contains complex decision making algorithm using a lot of sensors. The aim of the paper is to present a very simple., yet efficient approach of a basic flight phase classification., which is applicable in small unmanned airplanes., which have a limited computational and sensor capabilities. The flight phase selection system can be then implemented in an intelligent control and flight envelope protection system of such UAV., which are also presented in the paper.
