IntroductionFMC Update 10.8 has been standard in all aircraft delivered in after Feb 2009. A list of features is below. Following the discovery of several "anomalies", such as VNAV commanding the airplane to descend below the expected path on approach, Boeing issued a "service pack" in the form of Update 10.8A in 2010. Whilst this was in preparation Boeing stopped installing U10.8 in new aircraft and went back to U10.7 and also issued an SB for operators to remove U10.8. Unfortunately 10.8A still has some bugs which will be fixed in Update 11.
