No itís not! Just been on 460/461 and it was a 4 class 777-300 both ways. Very nice it was too.

Service excellent as well.

In the early 70's LHR to ABZ and INV were Viscount operated. In about 1976 Aberdeen services were operated by Trident 1E's, formerly from Northeast Airlines. These types, of which there were only 3 in the whole BA Trident fleet were much more suitable for the short runway at Aberdeen than the standard Trident 1C. The Boeing 737-200 then took over in early 80's followed by B737-400 in the 90's. As far as I can recall, LHR-INV continued with Viscounts until the closure of most UK and Ireland routes in about 1982 when Dan Air took on the route. Following their acquisition by BA, B737-400 were introduced until BA stopped the route altogether.

The scheduled type on the BA460/461 is the B777-300ER with the occasional -200 subbing. Hence, shouldn’t be that old.

Or indeed a substitute narrow-body, on half-a-dozen occasions so far this year.

They didn't overrun by much to be fair...

Thanks - Ah yes now I remember the OneE's on the Bravo's next to our DC-9's and Viscounts

G-ASWU was always around...

In the evening the last flights were our MME & LPL and BA's NCL and ABZ all around 2030

Has Heathrow's ATC had recent improvements or are some airlines on strike/affected by the weather? A/c seem to be holding much less and even avoiding S-bends over London.

No airline is immune from the effects of the weather. Low visibility will typically mean a lower landing rate and more holding compared to when the weather is good.

A/c seem to be holding much less and even avoiding S-bends over London.
Holding is simply a function of the rate at which aircraft are arriving in the TMA versus the landing capacity of the runway(s). Enroute delays and disruptions can lead to bunching of arrivals and therefore more/less holding.

As for S-bends, there are plenty of those visible on the flight trackers currently. They will always be more apparent when LHR is on westerlies, for reasons that will be obvious if you look at the locations of the holds in relation to the airport.

And yet, standing in a playground in Barnes this afternoon I would say they were lining up with the runway over Clapham rather than almost Ilford, in one case actually over Barnes.

Yes: https://www.nats.aero/tbs

And recategorisation of wake vortex minima which is a global initiative.

That's entirely possible, particularly for arrivals via BNN and OCK where the downwind leg is long enough to lose enough height before intercepting the ILS. Watch arrivals via BIG and LAM and you will typically see them joining further out after the usual S trajectory from those STARs.

If nothing's changed in the past few weeks then I must just have been looking on slightly unusual occasions.

Well you can easily check flightpaths of the arrivals you were observing here:

https://webtrak.emsbk.com/lhr4

and compare them with the norm at other times. WebTrak has a year's history available.

There must actually be stats relating to how much holding there is for arriving flights, mustn't there?

Yes.

The data for Heathrow originates, as you might expect, from ATC (i.e. NATS), but the airport itself publishes a month-by-month summary of average and maximum times spent in the hold in its annual Airspace and Noise Performance reports here.

The most recent figures I've seen (for 2017) are an average of 4.2 minutes holding per flight over the year and a maximum of around 50 minutes. The 2018 report will be out some time in the Summer.

On that basis, almost every accident only just happens. Spearing an aeroplane into the ground barely penetrates by more than a few metres, so even that wouldn't crash "by much to be fair" either!

Thank goodness the Tenerife collision only happened by a few metres - imagine how badly that could have turned out if they had really hit big time...

To be fair, the damage to Zulu Uniform was much more extensive than was at first apparent:
