GPS allows for closer spacing and straighter flight paths allowing
more flights to be handled in the same time span. About 25% more.


If they are heavies, the separation for wake turbulence is what the limiting
factor for separation, isn't it?

You need up to six miles behind a heavy. Your spamcan needs four miles
behind a large, such as a B737. To say GPS increases available capacity
25% is ludicrous.
