Simple virtual attitude sensors for general aviation aircraft

摘要

Purpose - This paper aims to present a proposal of a simple analytical redundancy method using for virtual attitude reference system design. The main idea of the project is applied typical on-board general aviation aircraft equipment for solving pitch and bank angles. Design/methodology/approach - The presented solution is based on satellite navigation and air data computer signals, which are independent from basic attitude and heading reference system. The concept described is related to the kinematics relations and aerodynamic forces formulas. Findings - The paper shows that the virtual attitude sensors are used by failure detection and reconfiguration subsystem and as a standby attitude reference system for general aviation aircraft equipped with augmentation control system applied for improving safety and efficiency handling qualities of aircraft. Originality/value - This solution allows improvements in operating properties of already existing and newly designed executive aircraft, as well as establishing a higher level of flight safety.
