Light general aviation airplanes become more affordable means of transport for the still raising group of people. This fact brings few consequences, of course. One of them is a set of problems appearing when inexperienced pilots start using such planes. Their habits and reactions to external factors are different to behaviors of professional pilots. So it seems to be purposeful to create the control system adequate to expectations of this group of pilots.

“…It is worth mentioning here that it was the first UAV control system built in Poland. During the years 2000-2006, the team of researchers working at the Department of Avionics and Control Systems was focused on an indirect (fly-by-wire) flight control system for a small general aviation (GA) aircraft (Tomczyk, 2002, 1999, 2003). It may have been the first fly-by-wire flight control system for a small GA aircraft in Europe or even worldwide.…”

Purpose The purpose of this paper is to present the topic of control computers diagnostics. They are part of an unmanned aerial vehicle (UAV) control system implemented in a modified version of MP-2 Czajka aircraft. Design/methodology/approach The algorithms were designed as a basic version of the diagnostic system. The system is open and will be developed. Findings First results show that the diagnostic system works properly. The system is easy for implementation and burdens the control computers only insignificantly. Research limitations/implications The system presented can detect only computers out of work. In its present version, it cannot detect such errors as improper calculations of control signals. After first in-flight testing, the system will be further developed. Practical implications The diagnostic system is implemented in an UAV technology demonstrator. Originality/value The designed system is the part of an UAV control system, designed for ground observation. Such technology demonstrator and flying laboratory enable different type of research in the area of aviation.

Purpose -This paper aims to present the design of a stability augmentation system (SAS) in the longitudinal and lateral axes for an unstable helicopter. Design/methodology/approach -The feedback controller is designed using linear quadratic regulator (LQR) control with full state feedback and LQR with output feedback approaches. SAS is designed to meet the handling qualities specification known as Aeronautical Design Standard (ADS-33E-PRF). A helicopter having a soft inplane four-bladed hingeless main rotor and a four-bladed tail rotor with conventional mechanical controls is used for the simulation studies. In the simulation studies, the helicopter is trimmed at hover, low speeds and forward speeds flight conditions. The performance of the helicopter SAS schemes are assessed with respect to the requirements of ADS-33E-PRF. Findings -The SAS in the longitudinal axis meets the requirement of the Level 1 handling quality specifications in hover and low speed as well as for forward speed flight conditions. The SAS in the lateral axis meets the requirement of the Level 2 handling quality specifications in both hover and low speed as well as for forward speed flight conditions. The requirements of the inter axis coupling is also met and shown for the coupled dynamics case. The SAS in lateral axis may require an additional control augmentation system or adaptive control to meet the Level 1 requirements. Originality/value -The study shows that the design of a SAS using LQR control algorithm with full state and output feedbacks can be used to meet ADS-33 handling quality specifications.
