I was still working there until late autumn and I'm not aware of any changes to procedures, unless they have been instigated since I retired. "Flight path" is something of a misnomer because it suggests something which may be regular or permanent whereas the tracks flown by inbound aircraft to Heathrow vary by the minute. It will depend on how busy they are, how many aircraft are off the stacks, prevailing wind, spacing on final approach, etc. The actual tracks flown are determined by the radar controllers and are entirely at the discretion of the indivdual controller at the time, within certain limits. However, if by some coincidence you're a happier man then good on yer! Personally, when Heathrow is on easterlies the more that fly base legs over my house the better.... even if I do feel a little sad at not being at West Drayton "doing it".
