“…On November 18, the US Federal Aviation Administration (FAA) lifted the ban on Boeing 737 MAX airliners, which had been in effect for more than a year and a half, after appropriate modification of the MCAS software [10]. At the same time, the question remains about the permissible level of compensation for structural "imperfections" of both civil and military aircraft using the automatic control system [11,12] and ensuring the required reliability of operation of the "pilot-control system-aircraft" system.…”

The paper presents the results of a study of the flight dynamics of a hypothetical maneuverable airplane, the shortcomings of the stability and controllability characteristics of which are compensated by algorithms of the system of improving stability and controllability by introducing a complex border of the permissible angle of attack depending on the flight mode. The research was based on a mathematical model of the airplane as a material point, taking into account the restrictions on altitude and flight speed, g-load, angle of attack, as well as the rate of change of g-load and roll. The purpose of the research is to establish the effect of the operation of the specified control system algorithms on the nature and area of safe execution of the "coup-type" maneuver. As a result of the research, it was found that the functioning of special algorithms of the electric remote-control system, leads to the emergence of areas of the operational range of altitudes and flight speeds, in which there is a significant and sharp deterioration of the maneuverability of the aircraft. Consequently, any "improvement" of the aircraft's flight performance using an automatic control system requires an assessment of the effect of these changes on the aircraft's maneuverability in all possible flight modes.

This paper presents the conceptual design and optimization of 2-seater seaplane. A design code was developed from MATLAB with optimization toolbox. Design synthesis contains aircraft weight, performance, aerodynamics, aircraft stability, engine sizing and ship hull design according to user requirements and Standard Specification for Design and Performance of a Light-Sport Airplane. The seaplane take-off weight is used as the objective function to minimize subjected to design constraints. The optimization process makes use of the MATLAB GA-hybrid scheme (Genetic algorithm and Fmincon) which is faster and more efficient than the genetic algorithm or gradient-based approach. The optimum designs were obtained. The influences of design requirements and constraints were investigated. The outcome of the program is an optimum design of a single-engine 2-seater seaplane.
