Flight safety and simulation

Aviation safety is the eternal mainstay of the aviation industry and the foundation for the survival and development of civil aviation. The core of blockchain technology is to provide credibility, which can ensure the provision of high credibility data between participating entities without mutual trust, especially suitable for environments with high discreteness and weak trust. Therefore, blockchain technology is suitable for application in the field of aviation security.

1. Pilot Full Lifecycle Management System (PLM) Based on Blockchain

The PLM system integrates the core competence, psychological competence and conduct competence of pilots in three dimensions. Based on the same underlying methodological theory of building index system, it has established an "all-in-one" evaluation model with multi-dimensional, full-cycle and big data characteristics. It has enriched the connotation of job competence based on the management practice of civil aviation in China.

Big data in PLM lays the foundation and support for the input and output of the whole system, and is an essential part of the system construction.

ACCEL has actively studied and explored the construction roadmap of PLM system, and jointly developed a PLM data management platform based on blockchain technology with Zhuhai Xiangyi in early August 2022. By combining the advanced blockchain technology with PLM construction of training centers, it aims to provide effective solutions for the big data part of PLM construction in various airlines and training centers.

ACCEL has actively studied and explored the construction of PLM system, and established a PLM data management platform based on blockchain architecture. Its main features are as follows:

  • Storing and calculating all flight, training and evaluation data of pilots in the whole life cycle to ensure the unity, integrity, confidentiality, reliability and traceability of data;
  • Standardizing the data and business processes of PLM system by using blockchain technology to enable it to be widely used nationwide, open up data barriers of various airlines, eliminate data islands, and integrate data resources;
  • Using the high reliability, interoperability and confidentiality provided by blockchain technology to solve various problems of PLM system data;
  • Using blockchain technology to build PLM big data to provide data and technical basis for further realizing scientific "portraits" of pilots through scientific and technological means such as data mining and artificial intelligence.

2.Blockchain based management of aviation equipment and components

The blockchain based aviation equipment and component management system has achieved full lifecycle tracking of aviation equipment and components. Using blockchain technology to integrate suppliers, manufacturers, and operators at all levels into the same system. Effective tracking of the circulation of aviation equipment and components within the system; The characteristics of blockchain technology itself ensure the authenticity and trustworthiness of aviation equipment and component information; Meanwhile, smart contracts can meet the process requirements between various levels of business entities. Combine the core requirements of data trustworthiness, sharing, confidentiality, and traceability to achieve them simultaneously. The system will effectively record transactions between all relevant parties, track aviation equipment and components, and promote leasing and sharing of aviation equipment and components. This will greatly save time and capital costs while improving the credibility and reliability of aviation equipment and component information, and improve the efficiency of aviation equipment and component utilization.

3.Blockchain based ADS-B protocol network

The ADS-B protocol network based on blockchain enables aircraft to transmit ADS-B data packets on the blockchain network without changing the airworthiness of existing ADS-B devices. Due to the use of blockchain, all on chain entities have a trusted identity authentication mechanism, which improves the credibility of the entire system; Blockchain technology has transformed ADS-B protocol information from plaintext transmission to ciphertext transmission, solving major security vulnerabilities such as third-party spoofing and denial of service (DoS); The access control mechanism of blockchain also meets the needs of flight data privacy. Blockchain technology makes ADS-B data "immutable", "traceable", and "traceable" during transmission, greatly enhancing the data security of the ADS-B protocol.

4.Blockchain based System wide Information Management System (SWIM)

ACCEL has built a blockchain based system wide information management system (SWIM) using blockchain technology, establishing a unified architecture, standards, and models to integrate various existing aviation transportation service systems. This system integrates numerous existing aviation entities (such as airports, air traffic control, airlines, etc.) to achieve timely and trustworthy sharing and interaction of data among various entities and systems, providing a prerequisite for collaborative decision-making.

5. Participate in the development of data exchange requirements for civil aviation flight simulation training equipment - group standards

ACCEL actively participated in the formulation of data exchange requirements for civil aviation flight simulation training equipment based on its significant advantages in related fields. ACCEL has rich industry experience and professional knowledge, which enables it to fully consider various practical situations and needs in the process of formulating data exchange requirements. At the same time, ACCEL technological strength and innovation ability also provide strong support for formulating high-quality requirements.

6. Work closely with Zhuhai Xiangyi, Capital Airlines, and others to conduct EBT/CBT simulation training research

Analyzed the QAR data format and content of JD5617 and JD5892 provided by Shouhang, analyzed the tail end QAR data with the Flight Profile Specification provided by Airbus authorization, and verified it using A320neo FFS

Visualize and replay the flight parameters of a specific flight during a certain time period, from which it is possible to clearly identify the various flight parameters of the aircraft and whether the corresponding pilot operations meet the corresponding quality requirements;

Complete "restoration" of environmental parameters such as wind, temperature, and turbulence during a specific flight period on a full motion flight simulation training device, and train pilots to perform safety operations such as avoidance or recovery in this state.
