6.5. FUTURE SYSTEMS
6.5.1. HONEYWELL RDR 4000
The Honeywell RDR 4000 uses the buffering of weather data in a 3D data base thanks to a multiple scanning. The RDR 4000 supports the weather radar function in the A380 AESS (refer to 7.1.4 – Weather Radar Function). Honeywell and AIRBUS are studying the opportunity to install the RDR 4000 on A320 family aircraft for early 2010 and on A330/A340 aircraft for end 2010. The RDR 4000 builds the weather display based on the 3D data base. This method improves the weather awareness and the workload of the flight crew. The RDR 4000 on A320/A330/A340 aircraft will propose new features (refer to 7.1.4 – Weather Radar Function for details):
- The automatic correction of the Earth curvature,
- Automatic modes to display on-path and off-path weather,
- The elevation mode: extraction of weather information via a horizontal cut across the 3D buffer.
