Introduction
Background of Standard Revision and Technological Evolution
MH/T 4042-2023 is a comprehensive upgrade of the 2014 version of the standard. The main technical changes are reflected in:
| Technical Dimensions | 2014 Edition | 2023 Edition |
|---|---|---|
| System Architecture | Hardware Requirements such as Dual Network Redundancy | Modular Four-Level Architecture (Appendix A) |
| Alarm Types | 6 Basic Alarms | 15 Hierarchical Alarms (Chapter 5.4) |
| Lighting Control | Single control mode | Three-stage guidance (single light/light segment/interval) |
Core function technical requirements
1. Monitoring service
The system needs to support at least 8 signal accesses such as SMR and ADS-B. The key indicators include:
- Target positioning accuracy in maneuvering area ≤12m (95% confidence level)
- Probability of track interruption <10-6 (>5 seconds)
- Target reporting delay ≤0.5 seconds
2. Warning service
Add the concept of runway protection area (RPA), and the warning response time requirement is <0.5 seconds. The key points include:
Implementation suggestions
System graded configuration
According to the functional configuration table in Appendix A:
- Level I system: basic monitoring + emergency alarm
- Level IV system: full functions including lighting guidance
Test verification points
Key indicator test method example:
| Target accuracy test | Use high-precision positioning vehicle, 200+ sample points for verification |
| Light response test | Need to be verified with class=instrument>Aids to navigation lighting monitoring systemClock synchronization |
