A380 Routings off Lambourne when landing on 09s at Heathrow
I have noticed on more than one occasion that A380 aircraft are given what you could say was a direct route to lhr over West London when landing on 09. All other aircraft fly the normal rroute being over north west lLondon then turn over Maidenhead.
Emirates and qantas are the ones that i have noticed take this route. Does anyone know why they take this route which takes them to the south of the field to make the approach. The only reason i can think off is for easy gate access ie next to 9L.
Thanks in advance

Simple: for reasons unkown to me, they generally put those flights on the "wrong" runway, 09R. Today at Heathrow I watched a BA A380 cross the 09L approach in a generally NE to SW direction, before joining the approach to 09R. The Emirates & Qantas A380 arrivals this afternoon also went south of the airport from the Lambourne hold to join 09R from the south.

09L exit A5 is shut, this is the first one available to the A380.
If an A380 rolls past A5 then it enters the localiser critical area which means we cannot use the ILS until it vacates the runway.
Therefore, we currently land all A380s on 09R.

Why intercept the localiser for 9r from the south and not from the north side as this is the normal approach when leaving Lambourne. The question is still open

In the case in question, because it makes it far easier for the final director as the A380 doesn't have to cross the path of the 09L inbounds. It's a procedure which is employed frequently in early mornings for all types of aircraft when both runways may be in use for landings. It may also be used in other situations when one runway is in use for landing to provide extra track distance or in poor weather for example.

HD,
Now that is interesting. Yesterday seems to have been an exception as most, if not all, inbound A380 flights crossed the 09L approach.
EK1, for example, sneaked across between the inbound United 787 and a BA A319. The B787 had come from the Ockham hold and had crossed the 09R approach (as is normal), while the Emirates A380 came from the north.
Later, BA flights BA268 & BA282 also approached from north of the airport and crossed the 09L approach, as did MH4.
What was interesting was the view of the BA 282 as it passed about 1 mile to the west of I was stood with the rest of the "ooh aah" crowd on the Terminal 5 spur.
Regardless of all that, it is nice to know there is at least a temporary valid reason for the choice of 09R!

Whilst there are "normal" procedures, what actually happens is in the hands of the radar controllers so there may be many occasions when things look different to usual. I suspect that the "over the top" routeing is only being discussed now because of the A380s but it does happen quite a lot.

Just to be clear though, there is no restriction on landing runway on easterly ops, so there doesn't actually have to be any reason for any aircraft to land on 09R. Or perhaps more accurately, 'because I felt like it' can be reason enough!

...and the departure rate?

It also depends on how busy TMA EAST and BIG are. If it is possible, the 09R landers from LAM get "stack swapped" to the BIG hold so that they are presented to Heathrow App on the south side, saving them doing the cross over that you described.

DRUK,
Without sounding facetious, the answer to your question is 'it depends', which was my point.
Yes, on paper, if you assume a schedule of 40-42 departures an hour, you'd think that one or two A380s arriving per hour would not have much effect, and I could quote the average time lost on the departure runway for an A380 arrival, but rarely are things identical to the average at LHR.

What Webtrak and all the clever statistics do not show is what is actually going on at Swanwick and Heathrow regarding tactical decisions by the controllers.
