Low-altitude flight of an aircraft is an effective, but at the same time, a very complex tactical technique, during which the crew does not always have the opportunity to timely recognize the occurrence of an abnormal case, determine the way out of it and counteract an aviation accident development. Despite many advantages of the automatic mode of low-altitude flight performing, its practical implementation is associated with a number of features and disadvantages, which determined the preference for the manual mode of low-altitude flight control. These are the presence of telltale factors, limited ability of performing flights at night and in difficult weather conditions, insufficient reliability etc. The considered features determined the relevance of the of low-altitude flight safety ensuring problem in relation to the manual control mode. As a result of an experimental study of the low-altitude flight performing process in a manual control mode, it was found that when performing manually-controlled low-altitude flight, a hazard assessment of the flight situation becomes pivotal. However the crew being under such conditions is not always able to correctly assess the flight situation hazard due to a combination of objective reasons. The current state of the adaptive and on-board flight safety systems theory makes it possible to increase the safety of the manuallycontrolled low-altitude flight by using adaptive control algorithms based on the flight situation hazard assessment. To solve this problem an adaptive control algorithm is proposed that ensures the formation of a security corridor in the longitudinal control channel, where the upper limit is determined by the critical value of the aircraft detection hazard, and the lower limit is determined by the critical value of the error in maintaining a given flight altitude. For a continuous assessment of the flight situation hazard and the timely formation of control signals the complex information about the current true flight altitude and the foreground is needed. Taking into account the peculiarities of low-altitude flight a digital terrain map containing data on natural and artificial obstacles along the flight route is a more rational source of information, that will make it possible to predict the development of the flight situation hazard. The above reasoning makes it possible to form an aircraft low-altitude flight adaptive control algorithm. A distinctive feature of the proposed algorithm is the implementation of a combined control variety where the pilot is provided with ample manual control opportunities within the security corridor, and the automatic flight control system is assigned the role of a safety subsystem that ensures control and timely return of the flight situation to normal flight conditions. The presented algorithm will allow to increase the crew logical-analytical activity information support during continuous analysis of the existing flight situation due to the formation of protective control actions based on the current flight situation hazard analysis.

This article presents the review of modeling and control during the airdrop process of transport aircraft. According to the airdrop height, technology can be classified into high and low altitude airdrop and in this article, the research is reviewed based on the two scenarios. While high altitude airdrop is mainly focusing on the precise landing control of cargo, the low altitude flight airdrop is on the control of transport aircraft dynamics to ensure flight safety. The history of high precision airdrop system is introduced first, and then the modeling and control problem of the ultra low altitude airdrop in transport aircraft is presented. Finally, the potential problems and future direction of low altitude airdrop are discussed.

The article discusses the formation of complex tasks of information support processes of development, manufacturing and subsequent mass long-term operation of new and advanced aircraft, aimed at further development of innovative approaches to integrated cross-industry system (platform) after-sales support of technical and flight-technical operation of civil aircraft. The article reveals the content of the main tasks focused on ensuring and managing flight safety in civil aviation of Russia and interrelated with the recommendations and legislative requirements of Annex 19 to the ICAO Convention and the Safety Management Manual. The most important factor in this case is to take into account the most complex requirements for the flight safety management system associated with maintaining the airworthiness of aircraft as a mode of transport of particular risk of use. The analysis was carried out and the General Scheme of the Multifunctional Integrated Platform was developed within the framework of the Information and Analytical Support System for the technical operation of aircraft components in relation to the scientific and production enterprise "Aerosila". The developed integrated platform realized in this air enterprise and providing information support on the allocated main functional modules is presented: the module "Safety Management System"; the module "Quality System"; the module "Certification" on the allocated objects of certification. As a result, a common information and analytical system was built, taking into account the degree of its implementation in the conditions of “Aerosila” air enterprise.

The characteristics wind field impact flight safety, trajectory keeping, and navigation performance of Micro Unmanned Aerial Vehicles (MUAV) directly. Accurate wind field measurement is a premise for MUAVs to take various pre-reactions to gust disturbance. Due to its small size, light weight, and low speed, MUAV is easily affected by gust disturbance during its flight at low altitude. Real time wind speed estimation and flight control strategy adjusting can reduce the impact of gust and enhance flight safety. This paper proposes a method of using airborne IMU, GPS, and pressure sensors to estimate wind speed. Experimental results show that this method can effectively estimate wind speed accurately, and has important application value.

AbstractRecent days there are many projects of UAV urban applications, moreover, although in different habited area. Several concepts like urban drone taxi, flying boards, flying bikes, etc. are in phase of prototype system test and evaluation. As part of the modern robotization, UAVs are in the focus of attention of numerous scientists. UAVs, as special platforms are widely used by the Military in different scenarios and different flight missions. Capabilities of UAVs used in non-military applications (i.e. Police applications, disaster management applications, border control, firefighter applications, etc.) will serve well the idea of UAV 3D (Dirty-Dull-Dangerous) application. The purpose of the author is to derive those low altitude UAV flight regimes when low altitude flight automation in necessary due to flight safety aspects, or, due to any existing regulations, and, finally, find and propose flight paths of the UAV better fitting given mission of the UAV.
