SEATTLE, Aug. 20, 1999 -- Boeing commercial airplanes are not affected by the Global Positioning System (GPS) clock-resetting event that occurs at midnight tomorrow, The Boeing Company announced today.
GPS is not designed or used as the sole means of navigation on Boeing aircraft. GPS is used in conjunction with radio navigation and inertial navigation systems to enhance airplane position information. Boeing airplanes are designed with redundancy for all flight-critical operations.
The company has tested all of its airborne systems for upcoming computer anomalies, including GPS: Sept. 9, 1999 (which could be read by computing systems as a repeating series of nines), Jan. 1, 2000 and leap year 2000. No safety of flight issues exist.
