The MLS test bed installed at the FAA Technical Center was transported to, and temporarily installed at Chicago's Midway Airport. Three engineering flight tests were conducted on August 27, 28, and 29, 1988, to verify and characterize system operation. On August 30, three demonstration flights were conducted for the aviation industry, the media, and FAA personnel. Three profiles were designed for these flights to demonstrate the operational capabilities of MLS. The operational capability of MLS was successfully demonstrated and the MLS signal in space met Category II instrument landing system (ILS) tolerances. (fr) 收起
