Pratt & Whitney has installed the first JT8D-200 series QuietEagle noise reduction system on a VIP McDonnell Douglas MD-87. The system, which includes a 16-lobe internal mixer, exhaust muffler, tabbed nozzle and improved front fan case, is said to bring JT8D-200s into compliance with FAR Part 36 Stage 4 and ICAO Annex 16 Chapter 4 noise standards.
