The Airbus I fly now can determine its position to a few metres and it varies the bank to stay on the arc. It is easier to leave the autopilot engaged whilst it does this
i remember the first one in the UK was at Biggin and caused much confusion. It was around the mid eighties. How many on here remember QDM approaches? I flew my last QDM approach in 1989, the controller and I were chatting about impending retirement over coffee today.
