RW 15 - Standard procedural or radar vectored approach for inbound traffic from west, east or south is to the west of the airfield thus overhead Birmingham city centre with an intercept heading overhead the Walsall FC stadium before ILS capture.
RW 33 - When BHX is busy inbound aircraft from south or east may be directed to Honily before a descending orbit or part orbit to the west of the extended 33 centreline before final vector to establish just north of Warwick.
Hope this helps
