Let me put it this way:
You are vectored to intercept the localizer/glideslope and end up high on the glideslope.
DO YOU:
1. Request a vector back on to the localizer below the glideslope.
2. Increase rate of descent and intercept glideslope from above>
You get to choose. You make the choice. ATC may even apologize and give you number 1, but it is your airline's fuel, money, schedule. ATC doesn't refund fuel cost do they?
ADD in wake turbulence. Do you fly on the glideslope or do you fly a little above and land past the landing point of larger plane ahead of you?
I am certainly aware of the way things OUGHT to be. But I know how things really are.
