Embodiment Construction

[0028] The technical content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] In order to make the aircraft smoothly enter the process of level floating and landing, the approach phase must strictly abide by the standard operating procedure (SOP). The approach stability evaluation method based on energy management provided by the present invention utilizes the concept of energy management to design a stable approach evaluation criteria, and the relationship between unstable approaches and energy. By selecting the parameters associated with the approach stability in the flight data, a stability evaluation formula is established to identify the unstable approach state and provide a basis for unsafe event monitoring and risk identification. The invention can effectively improve the identification accuracy of unstable approach, provide reference for flight risk identification and pilot train...

Abstract

The invention discloses an approach stability assessment method based on energy management. The method comprises the following steps that: S1: collecting flight data, and extracting parameters used for approach stability assessment; S2: utilizing two parameters including flight height and ground velocity to calculate energy height; S3: calculating an energy conversion boundary condition function in an approach to landing process of the airplane; and S4: through a difference value of the energy height and the energy conversion boundary condition function in the approach to landing process of the airplane, judging approach stability. By use of the method, an energy management concept is used for designing a stable approach assessment standard and a relationship between an unstable approach and energy, a basis is provided for unsafe incident monitoring and risk identification, the identification accuracy of the unstable approach can be effectively improved, a reference is provided for flight risk identification and pilot training, and safety management levels and training efficiency can be effectively improved.

Description

technical field [0001] The invention relates to an approach stability evaluation method, in particular to an energy management-based approach stability evaluation method; it belongs to the technical field of flight quality monitoring. Background technique [0002] With the development of society and the improvement of people's living standards, air travel has become more and more common, and people's requirements for flight safety are also getting higher and higher. Flight quality monitoring is an important tool and means for safety assurance of airline flight and safety management departments. It can realize continuous monitoring of flight control and operating environment, quantitatively measure and effectively predict changes and deviations of safety risks or risk control measures, and monitor known safety risks. Risk, to detect emerging safety risks, determine necessary corrective measures, and provide an objective basis for evaluating the effectiveness of the safety man...
