I did an ILS into Liverpool (IF Training sortie) recently (in a helicopter) and noticed an Easy Airbus held up at the holding point for several mins. I did feel quite guilty about time is money as we fought against a fair descent headwind. But I think I am right in saying that once anything is inside 3 miles and thus cleared to land/overshoot, you have to wait regardless of how big you are.
There was also a Dash 7 doing training visual circuits at the time who almost certainly followed me in and may well have held him up even more as I scuttled off to the peace and quiet of Hawarden.
I suppose that if your employment consists of doing a short haul route 6 or 7 legs in a day, all of these 'little delays' add up to one unhappy chappy.
What goes around comes around though, for an Auster taking 5 paces foward and 3 paces back held us up from a visual runway crossing a few days later. The differance was that I quite enjoyed watching the little chap make his 3rd and final landing (within 15 seconds) followed by a full stop in about 60 yards.
