Oval,
You are right. Our fear of green is just another cxample of being overly conservative for no gain in safety at the expense of efficiency.
Sue,
You are also correct. When pilots do this, it does not help ATC do their job well.
Geh065,
What a ridiculous comment! I suppose we should expect nothing less out of the Airbus fleet office. Do you also exclusively use the auto pilot at the expense your hand flying and landing skills for those passengers so they can have a smoother ride. Yellow should be avoided when practicable, but green is more than OK with the seat belt on, especially when the cabin crew are seated. Sure, fly around green when it costs almost nothing, but the terminal area is not the place for this when there is a lot of traffic.
