GPS allows for closer spacing and straighter flight paths allowing

If they are heavies, the separation for wake turbulence is what the limiting

Well, wake turbulence is certainly a factor, particularly for the A380
which may slow down things even further. Which raises the question as
to whether it should be penalized more than others if they start to
use penalties.
