SFO BA A380 takeoff on 1R?!?!

Sun Sep 17, 2017 7:16 am

Three months ago I was spotting at SFO for Finnair's inaugural flight.

When I checked the Flightradar24, I saw something really unusual of where BA A380, rather than going on taxiway Lima and going off 28R, it just stopped at threshold of 1R. Then I was pretty shocked to see that, an A380 blasts out of runway 01R?!?! Runway 1R is only 86500ft long, so I wonder is it too short for a typical A380 to takeoff?? I literally swore at myself after I saw the way that she took off? I think any heavies other than KLM (747,777,787) use 1R are rare.

Has anyone else seen an A380 going off 1R or similar length like that, if so does anyone think it is rare?

Btw I am new to a.net, I finally decided to post something!

Hi,

Welcome to A.net! Indeed it is unusual to see the A380 depart off 01R however not impossible. The only 2 runways BA A380's are authorised to depart from at SFO are 19L/01R and 10L/28R. Landings however are forbidden on 01R/01L.

But 28L also seems enough for A380, I wonder why they aren't allowed to use 28L

IIRC I've also seen LH's A380 departing from 1R @ SFO.

So yes maybe uncommon, but certainly heard of in terms of A380 going from 1R.

Imagine if KLM have A380s and send them to SFO, would they do 1R every day, as they do 1R all the time :D

16 miles would be long enough for any aircraft. ;)

Well, just about comfortable for the A340 :airplane:

I meant to say 8650ft

They're only going to Europe. They probably are only barely half filled with gas.

I'm almost certain a KLM 747 took off from 1R yesterday...

Interesting. Are any other types forbidden from landing on the 1s?

When I was a child growing up in Millbrae, approaches to the 1s were straight in over the hill rather than the current circling to land. I think that is well over a 3 degree glide slope. Takeoffs from the 19s turned South after takeoff though.

They do it everyday except straight 28 departures

They do it occasionally. Fun to see the big A380 flying (relatively) low over me in Oakland.

It is all to do with take-off performance and balanced field length. Basically the aircraft has to accelerate to V1, lose one engine, become airborne and clear a 35ft obstacle however, the airborne part does not have to be over paved surface. Where the runway meets the sea, as in this case, it means that pretty much the whole runway length can be used, so the aircraft can nominally be seen to be taking off from a shorter runway that would otherwise be the case.

Didn't know this! I've got to take a KLM 744 out of SFO now and hope I get a 1R departure!
oh boy, here we go!!!

I see European departures off the 1s all the time from just about any widebody capable of doing those routes (including 767s).

The A380 wing was designed around two larger variants, the A380-900 and A380-1000, neither of which, of course, were built. So the A380-800 has *way* more wing than it needs and it lifts off like a feather even when at MTOW.

There are multiple factors that fit into the choice of departure runway. Obviously, it has to be long enough, but there are other things outside of the aircraft's weight and capabilities. Among other things, the 28s are pointed directly away from Europe, so if you can take off of a runway that is approximately pointing at your destination, you can save 10-15 minutes of flight time, and thus 10-15 minutes of fuel. There may be ATC factors with how many aircraft are in the air in a given part of the region along a given departure track, or how many aircraft are arriving on the 28s. There is, of course, wind direction, and there is also a noise advantage to the 1s because they point at the water.

So if an airplane is capable of using the 1s, why not use them?

You would think that if a 744 could do the circle-to-land to the 1s that a 380 could do it.

I was on the afternoon KLM flight on July 11th this Summer, a B747 taking off on 01R. The short taxi was the trange part, really...]

I normally suggest 01R for departure from SFO. It probably saves 20-30 minutes on block time on the way back to LHR and there's plenty of performance in hand. You will always get a bigger thrust derate on 28 though, so some colleagues were initially keen to use 28. I think more people are getting used to the idea as they get familiar with 28R being a pain! I'm ex 747 so used 01 the whole time on that.

If there's a gusty strong wind down 28 then that's probably the better option still.

I’ve actually seen some Asian birds going off 1R, such as China Southern 77W. I don’t see any sense of it bc it is pointed away from Asia than 28s

Relative the distances involved, using one runway or another has an insignificant impact on total time and burn. However if the wind favours a certain runway, that is the safe option.
