Normally when you are coming up to a waypoint the FMGC will normally compute the turn at the waypoint but due to the radius of the turn the aircraft may begin its turn early to be able to turn smoothly onto the airway centreline. There may be times that you need to actually fly exactly over the fix before turning. One time I always user the overfly button is when approaching London Gatwick 08R as shown in the attached chart. If I turn normally it will bring me at the wrong angle into finals, so I use the overfly button on the MCDU, overfly the D23MAY/D5MID fix and the turn starts after it.Rob Elliott, EGPE InvernessPSS Airbus Support andAirbus Fleet Training Captain, British Airways Virtual airbus@speedbirdonline.co.ukhttp://www.speedbirdonline.co.uk/airbus.htmlhttp://www.bavirtual.co.ukhttp://forums.avsim.net/user_files/146459.jpg
