Someone asked a question the other day re how many stands/gates are there in T5A for longhaul planes (747/777). I thought it was 2 but I may be mistaken and it is only 1? Which gate (s) are they?

I can't seem to find a definitive answer despite searching here (and Google as well).

Also, can T5A take the 787's as well as the 747's and 777's as I suppose they will now be classed as very long hauls too.

It's just one of these things I'd like to know (I'm purely being nosey ) so thanks in advance for the answers. ^

I think the 747 stand is 518. Actually 516, and 513 look wide enound to accommodate a 747 too. I think the morning DME 747 uses 518, and I think the morning LAX service used to use it as well. 747 is shown at 518 here:

I am not sure 777 use T5A at all. It looks like the 747 is a snug fit to A18, and as a 747 is 64.4 m wingspan I would imagine a 777-200 at 60.9 m woud be ok as would a 777-300ER at 64.8 m.

I did wonder on 787s. There are a number of stands on T5A which can take a 767 so like you I was questioning whether we may see a 787 appear. However, I have just looked at the sizes:

767-300ER - length 54.9 m, wingspan 47.6 m
787-8- length 56.7 m, wingspan 60.1 m
787-9- length 62.8 m, wingspan 60.1 m

So the 787 is significantly wider than the 767 and (apart from 518) I wonder whether it would fit any of the stands at T5A which a 767 could use.

No 787s as yet IIRC. Some stands have restrictions for A320 sharklets due to necessary redesign or non ability of redirecting of inter stand roadways.

As for max aircraft size B747/777 stand 514. For the B747 it is 516 and 518. 767s can also fit onto 505/08/12/13.

The max permitted aircraft size on taxiway A (running north/south in front of T5A) is a B747.

Had my first 747 arrival at T5A on Monday of last week (12 Oct) on BA 176 from JFK. My initial thought as we taxied past the B and C gates was that we were on the way to a remote stand near where the mid-haul 321s are often parked; but no, it was gate A18 (I think) and it meant a little more time in the CCR before our connection.

Interesting that they share the same wingspan, I wonder how that affects the fuel efficiency of the -8 model.

Thanks KARFA, appreciated ^


Thanks Sigwx

Just my thing reading and learning about the technical stuff like you have posted. ^^^

Over on the Club World thread there is a question regardng the official ages for exit seats on the Upper Deck of the 747.

I started this thread as below, albeit a few years ago now, but can a BA Staffer please confirm what is the current policy/age restriction for the UD?

Is it Over 12 or over 16?

Thanks in advance ^

One for the pilots... why do you sometimes power the engines up in two stages on takeoff? I had originally thought it was to check the engines were performing properly but i recently read it is done to keep the nose from pitching up too much under acceleration into a headwind.

See the below video for an illustration of what i mean:

It's not sometimes, it's every time. Big fan jet engines are slow to accelerate from low power, and each engine will be variable. So we set about 30%, make sure they are balanced and then apply take off thrust. If you went straight from 0 - take off there's a good chance of losing directional control if say the left engines spool up faster than the right.

Skip to 21:35 for the moment in question, unless you fancy watching over 20mins of taxiing.

KARFA

The only commercial jet I can think of which was an exception was Concorde. Watching cockpit videos it seems they just went straight for take off power.

T8191

Possible reasons include:

1. Not having to spool up a big fan-jet
2. 4 x Olympus close to a/c centreline

Waterhorse

3. Reheat selection?

789 G-ZBKA parked at A18 (from the CCR) on the 13th (not the best pic, but shows it can fit in the same gates as the 744s.

They are basically the same aircraft, but the -9 has a "plug" fore of the wing and one to the aft, which basically extends the fuselage length.
