PSS A320 FMGS/MCDU Tutorial Part 1 (PreFlightConfigurations). This is the first of 2 or 3 videos for learning the use of the FMGS/MCDU. These videos are especially designed for newbies but you should be familiar with normal terms of airliner and Airbus A320 flying. Some parts of the clip are played very fast, so don't hesitate to pause the video and watch it again. By Paul Fletcher.
