It’s funny how things vary!! In my airline flying one dot above the G/S would put you right on the limits of an unstable approach and you would have to G/A if you drifted any higher. Thats why we would fly on the G/S but remain 5 NM behind the heavy, so you are clear of wake turbulence.
Guess my airline thinks runway overruns happen more often than accidents due to wake turbulence so they think there is more danger of flying high and landing deep rather than just following at 5 miles.
Landing performance is calculated on you crossing the threshold at 50 ft. 1 Dot high and you are invalidating this performance. If you did over-run not sure how the authorities would view this.
We don't quite go for forced arrivals but there is very much a culture of getting it on in the right spot!
I have not come across anyone who would intentionally fly one dot high, guess our SOP's are just a lot more prescriptive. That and a very active flight data monitoring deptartment!!!
