This has been discussed multiple times. It is typically due to operator and/or national procedural differences.

Re: aerospatiale A200 from the 1980'?

There was a lot of information in this book I used to have. If memory serves, the A200 project was one of the origins of the A300. It was merged into the project alongside a British concept if memory serves.

Re: Very basic question for pilots: How do airliners slow down when they are already at flight idle?

In level flight, the rule of thumb is 10 knots deceleration per nautical mile at idle, or double that with speed brakes. On the A330/A350, if you're descending and also need to slow down, it is often a good idea to just level off for a bit, decelerate, then resume descent. Much more relaxing than wa...
