"On August 25, 2001, a Fed-Ex 727-200 aircraft equipped with a Rockwell-Collins GNLU-930 Multi-Mode Receiver, conducted six full autopilot approaches and touchdowns during joint U.S. Air Force and Raytheon sponsored test flights, using the Joint Precision Approach and Landings System."

HISTORICAL HIGHLIGHTS FOR HARRY
Necessary Avionics Systems
On September 6, 1996 Rockwell-Collins Commercial Avionics announced plans by Boeing and major commercial airlines, to install Rockwell-Collins Multi-Mode Receiver (MMR) landing systems within their Boeing 757 and 767 aircraft.25The MMR system can utilize the WAAS signal as well as the basic GPS signal, the VHF, UHF, VOR navigation signals and eventually the LAAS navigation signal.
Achieved Systems Accuracy
During numerous FAA, U.S. Air Force and National Aeronautics and Space Administration (NASA) sponsored runway approach and touchdown test flights between 1994 and 2002, involving augmented GPS positional signals and the auto-land systems of Boeing 757, 767 and other Boeing 700 series aircraft, horizontal and vertical positional accuracies of just several meters orless were routinely achieved. The four aircraft used to carry out the September 11, 2001 terrorist attacks were also Boeing 757-200 and 767-200 model aircraft. Runways of major U.S. airports like JFK International, Chicago-O'Hare International and Los Angeles International are between 150 and 200 feet wide.30 31 32The WTC towers were each 208 feet wide.
During October of 1994 at NASA's Crows Landing Flight Facility in California, 110 autopilot approaches and touchdowns of a United Airlines Boeing 737 aircraft facilitated by augmented GPS positional signals, were successfully conducted, with "accuracy on the order of a few centimeters" being consistently achieved.34
During October of 1994, augmented GPS signal flight tests sponsored by the FAA in cooperation with Ohio University were conducted. 50 autopilot approaches and touchdowns were successfully performed by a donated United Parcel Service Boeing 757-200 series aircraft. The augmented GPS positional signal was integrated into the aircraft Flight Management System (FMS).35
During July and August of 1995, Honeywell, Boeing and NASA sponsored tests using NASA's Boeing 757-200 test aircraft and performed 75 autopilot approaches and touchdowns. The predicted augmented GPS system aircraft positional accuracy of 1-2 meters was successfully achieved.36 37
During October and December of 1998, WAAS signal enroute navigation and Category I precision instrument aircraft runway approaches were performed over the northern Atlantic ocean and in the nation of Chile, using the FAA's 727 test aircraft. Overall aircraft positional accuracies of 3-4 meters were successfully achieved.38 39
During August of 1999, multiple augmented GPS signal autopilot approach and touchdown tests were performed using a donated United Parcel Service 767 aircraft. These tests were sponsored by the FAA and were centered on the prototype GPS-based Local Area Augmentation System (LAAS), which is intended to compliment the FAA's WAAS service. The LAAS signal can provide aircraft positional accuracy of less than one meter vertically and laterally.40
