The examined scientific and technical problem concerns providing flight safety for Small Aviation and General aviation (GA) aircraft with the use of onboard software and hardware. Proposed by the authors  approach to the selection of scientific and engineering principles and methods, implemented in the algorithms of onboard computers when assessing the risk of a situation is based on the classification of the main causes and the corresponding types of aviation accidents and incidents during low-altitude flights of light aircraft in airspace with a high intensity of air traffic by the main typical features revealed on the basis of flight accidents analysis. The authors did an in-depth study on a rational option of complex vision system configuration, determined and justified a set of basic parameters of all the other components of the onboard system experimental sample, analyzed and compared options of possible technical solutions, on the basis of which selection and justification of the optimal variant of technical configuration by the hardware composition and the software structure of for the  prototype. https://www.biotech-asia.org/vol12no3/onboard-flight-safety-support-system-development-for-low-altitude-flights-of-light-aircraft/ flight safety; light aircraft; small  aviation; general aviation; onboard software and hardware; piloting errors; navigation errors; aircraft collision  in the air; collision with ground obstacles; low-altitude flight; crew  information support and intellectual support; technical vision system
