Busbar,
Depends on where you are coming from and which way the winds are on the day.
For a fairly decent guide (I would say that; I wrote it!) go to the pinkfroot web site. From the menu at the top of the page, click on Spotting, then Plane spotting. Choose Manchester and away you go, complete with Google Earth locations etc.
I say it depends on which way the wind is as, in the case of an easterly wind, you might want to watch the landings at the western end of 05R.
I will PM a direct link to the relevant page.
Oops! No I won't. Can't!
