Introduction
Interpretation of the core content of the standard
| System level | Core functions | Performance indicators |
|---|---|---|
| National Information Management System | National flight plan processing, cross-regional surveillance data synthesis | Simultaneous processing of 10,000 flight plans |
| Regional Information Processing System | Regional airspace coordination, localized meteorological intelligence processing | Support 32-channel ADS-B data access |
| Flight Service Station System | End-user services, emergency rescue support | 1,024 concurrent track processing |
Key technical requirements
1. System architecture characteristics
The standard requires the use of a three-level architecture system with modular design:
- Time base: UTC+8 Beijing time system is mandatory
- Coordinate system: The WGS-84 coordinate system is uniformly adopted
- Data synchronization: Clock synchronization error of ≤100ms is required
2. Core function matrix
Chapter 5 of the standard specifies the functional differences between the three types of systems in detail:
Flight plan life cycle management
Nine status transition mechanisms are clearly defined, including:
- Not submitted
- Pending approval
- Implemented
Implementation suggestions
Key points of system construction
- Security protection: National systems must meet the requirements of Level 3 security protection
- Data redundancy: Key data retention period ≥ 6 months
- Disaster recovery capability: National-level systems must achieve off-site disaster recovery
