Background Information
Smiths Aerospace has discovered an error in the Update 549849-015 U10.6 FMC software.  The software incorrectly processes wind data for certain downstream route legs which can result in erroneous values for ETA and fuel remaining for downstream waypoints. This anomaly also affects the ability of the FMC to control to a Required Time of Arrival (RTA) at a downstream waypoint. The error is a function of the entered/sensed wind, leg length, and course change between the incoming leg and outgoing leg for a downstream waypoint.
The 549849-015 U10.6 FMC predictions will be incorrect for leg segments that follow intermediate waypoints with a less than a two degree course change between the incoming and outgoing leg, for non-flyover points.  The error will occur for leg segments with less than a ten degree course change for flyover points.  This results in the FMC incorrectly applying winds for the particular leg. Depending on the magnitude and direction of the wind and the length and direction of the leg, the error in the ETA can range from nothing at all to more than 40 minutes. Fuel predictions and Mach targets will also be proportionally affected. This anomaly does not occur when there is a greater than two degree course change (ten-degree change for flyover waypoints) between the incoming and outgoing legs.
Flight Crew Operations Manual Bulletin No. SHZ-44, dated May 02, 2005 (continued)
Flight crews should not use FMC downstream predictions for ETA, RTA, fuel remaining or Mach number target when operating with 549849-015 U10.6 FMC software.  All predictions should be verified by conventional methods.
Boeing plans to revise, certify and deliver new 549849-016 U10.6 FMC software. Until that time, Boeing recommends all operators re-install U10.5A FMC software on those airplanes that delivered with 549849-015 U10.6.
Operating Instructions
When operating with 549849-015 U10.6 FMC software, do not use FMC predictions for ETA, RTA, fuel remaining or target Mach number.  Verify all predictions by conventional methods.
