Every one doing the full trombone leaves no leeway for spacing on final(4nm -8nm norm vortex) or any problems like, AMAN timings, go-arounds etc etc.
The shorter STAR is purely a fuel planning STAR as it recognised that you won't fly the full star most of the time!
Whilst on subject of spacing please don't slow below given speed without telling us! Most of the time the ones who do slow end up sending the one behind around and don't even notice any thing but an ATC Bollocking! Mean while some one behind is going around and doing an extra 40 track miles!! An example; un-named Super the other night given 160kts to 5nm gets transferred to tower next seen at eight miles doing 137kt ground!! 2xB777 behind back to min safe and just make vortex as do the two B737's behind them. The one decrease in speed effected at least four other aircraft!!
Thank you off soap box
