Introduction
Standard Overview
MH/T 2006-2013 specifies the minimum performance requirements for flight recording systems of small aircraft with a maximum certified takeoff weight of ≤5.7 tons, covering the four major recording systems: flight data, cockpit audio, airborne imaging and data link information.
Comparison of core performance requirements
| System type | Storage duration | Key indicators | Survivability test |
|---|---|---|---|
| Flight data recording system | ≥25 hours | Bit error rate≤10⁻⁶ | 1000g shock/1100℃ fire |
| Cockpit audio system | ≥2 hours | 16bit/44.1kHz PCM | 4.54kN static extrusion |
| Airborne imaging system | ≥2 hours | Class A 4fps/Class B 1fps | Optical resolution ≥256lp/IH |
Key technical specifications
1. Flight data recording system
- Parameter recording: Mandatory recording of 22 basic parameters such as heading and pitch angle (Appendix A)
- Synchronization accuracy: Time deviation of each channel ≤4ms
- Software level: Must comply with DO-178B Level E or above
2. Cockpit audio system
Case: A general aviation aircraft needs to start recording 5 minutes before the engine starts, the recording delay needs to be controlled within 50ms, and the regional microphone needs to meet 94dB dynamic range.
Implementation suggestions
- Newly installed airborne systems need to pass ground playback verification (Clause 5.7)
- Regularly check the aging of the recorder's flame retardant material (Clause 3.4)
- Establish a data erasure approval process to prevent accidental deletion of accident data (Clause 4.7.2)
