FMC Update 11

Contents

Introduction

FMC Update 11 was originally scheduled for 2010. Unfortunately Boeing had tried to issue it in time to bugfix U10.8 but the changes needed to be made quickly so efforts went into U10.8A instead of U11. The position as of November 2011 is that Boeing will not be announcing an expected date until Spring 2012, this porbably menas that U11 will not be available until Autumn 2012.

A list of expected features is given below.

All of the information, photographs & schematics from this website and much more is now available in a 370 page, 8.5" x 11" book available here.
