Range-payload Charts For Widebodies?

Tue Apr 08, 2008 3:08 am

Hello guys,

I come back with some more questions regarding range and payload.

I am basically trying to understand what sort of a/c could be used on certain routes. For that, I am wondering about standard-issue widebodies such as the 772ER and 333X.

Are there charts made available to the public where one could see how far these birds can fly with a full payload? Assuming they do take off at MTOW, if we fill up their tanks to the last drop, can they take on all passengers and luggage and freight (how much?)? And then how far will they go?

Thank you very much for any help.

Goodness no. If you fill the tanks on airliners, you would be restricted to half the maxi payload or less.

Range charts are available. Here are some "pretty" ones:
http://www.boeing.com/commercial/747family/pf/pf_rc_fgt_london.html; http://www.boeing.com/commercial/747family/pf/pf_rc_riodejaneiro.html; http://www.boeing.com/commercial/777family/pf/pf_rc_dubai.html; http://www.boeing.com/commercial/777family/pf/pf_rc_newyork.html

The PDFs are in the airport planning documents and provide more "geeky" formats:

It should be noted that range is very variable depending on winds on a particular day.

Thanks a lot, buddy.

I had already come across these graphs and they seemed quite optimistic to me. Judging by them, we could operate LHR-BKK with a 773 regular. Has any airline ever done that in scheduled service (i.e. with full pax and luggage load + freight)?

And I thought the 77L had failed to make SYD-LHR non-stop economically due to payload restrictions...

I have flown EK 405 a few times (MEL-SIN-DXB) with 773 regular and I was under the impression that these distances were its optimum economic/operational ceiling.

Thanks a lot anyway.

Links to several ACAP documents from Airbus, containing payload/range charts, can be found in this thread:

I think Eva Air are the only ever operator of the 773 between LHR and BKK, and that's with a 773ER.

But you'd be operating into the prevailing winds, increasing the equivalent still air distance and you've also got to throw in airways distances as opposed to great circle. And don't forget the effects of airframe/engine fuel mileage deterioration.

Payload-Range curves are for newly delivered airplanes and show still air ranges.

That is my whole point. Of course if we send a 773A from FRA to BKK, we have to bring it back to FRA somehow.

So would it be doable?

The load/range chart suggests that the payload for a 773A FRA-BKK would be close to 100K lbs. Assuming an 8% increase in ESAD westbound, the payload would be reduced accordingly.
This assumes that the aircraft weighs, to quote Boeing parlance "weight for a baseline configuration for 451 passengers"

Is there anywhere we can get the charts for Airbus planes?

I use the following link and change the text at the end of the URL to the model I am looking for.

Guys, I've finally found the link for the Airbus documents:
