China Demonstrates GPS-Based Instrument Landing System

John Croft | Aviation Daily

A China Eastern Airlines Airbus A321 and a Shandong Airlines Boeing 737-800 flew a series of instrument approaches to the Shanghai Pudong International airport on April 29 using a Honeywell-built ground-based augmentation system (GBAS) and instrument-approach procedures developed by Hughes Aerospace, marking the first public demonstrations of the technology in China.

The Honeywell SmartPath GBAS landing system (GLS)-which augments GPS signals to boost accuracy to required levels-is the first certified system to be installed in China. One GLS, which can output guidance for up to 26 approaches to any runway, replaces traditional instrument-approach architectures that require horizontal and vertical guidance systems to be placed at each runway end. The single system covers approaches for all four runways at Pudong and saves on a variety of regular inspection and maintenance costs.
