I'm sorry if this has been posted before... tried searching, but to no avail.

My question is: Qantas obviously runs 744's with both RR and GE stacks... but, is it just the GE ones that have the extra tank in the back end ?

You see both at LAX, and now DFW, some exit SYD, some MEL... and usually LHR get the RR's because they re - fuel, or am i way off the mark ?

Yes, all GE engines on 744ERs.

You can verify this on planespotters.net (maybe) and definitely on the PDF seat maps on Qantas' website.

And before you ask, 767s leased from BA have RRs, ones bought new have GEs.

They are usually confined to SYD-DFW, SYD-LAX, MEL-LAX, SYD-EZE and SYD-HKG. They can end up other places, but rarely LHR unless that has changed since A380s have taken over some LAX flying.


If you have never designed an airplane part before, let the real designers do the work!

That's mostly to do with the premium heavy cabin config. Apparently there's lower demand for F/J on the LHR flights than the LAX flights. But with the A380 they've gotten rid of that distinction. Go figure.

The extra tank is in the forward cargo just in front of the wing spar. I think there's still one non ER GE powered 744 in the fleet.

Correct, the one from Asiana Airlines. VH-OEB IIRC.

Please don't flame me here if this a stupid question,

But, so it doesn't matter fuel burn wise whether its a RR or GE, just the extra tank ?

The GE has a better fuel burn than the Roller with or without the extra tank. The GE is also somewhat lighter as well.

That. And it may also be that GE has an exclusive (had I guess since you can't buy a new 744ER anymore) on that subtype the way they do on the 77W & 77L/F. Otherwise, fuel burn aside, QF may very well have stuck with RR, being that there are only 6 ERs in the fleet (and world for that matter). It can't be a very good economy of scale, I would think...

There may only be 6 PAX ERs, but there are a fair few more ER freighters flying around.



I'm tired of the A vs. B sniping. Neither make planes that shed wings randomly!

I thought they couldn't obtain the -ERs with RRs?

As far as I'm aware, the 744ER was only offered with either PW or GE engines.

Yes, that's what I meant. The RR was never available on the 744ER, or else they probably would have boguht them that way. I didn't know P&W was a choice though; I thoguht it was only GE...

Is there a 63,000 pound RR engine that would have even worked?

Edit: there isn't. The -524G/H-T is only good for 60,600 pounds. Not enough for the increased weight of the 747-400ER.

I flew on two ERs recently, both GE's - OEH and then OEF.
With the 767's here's how I remember it - regos ZX* are RR's and regos OG* are GE's

Can OEB make the Texas run with the different engines?

Not with a commercial payload. Not a chance.

Ah ok. Because when I flew DFW-BNE there were serious restrictions.

The Boeing ACAP sheets show the RB211-524H8-7 as being available on the 744ER.
