B737-700ER Questions

Now that Boeing has announced the B737-700ER - a commercial version of their BBJ, I would like to know:
Other than the different wings and landing gear (taken from the B737-800), how is the commonality issue between the standard B737-700 and the ER version?
How much range per tank is added for each of the 9 auxiliary fueltanks that aircraft can take? Specially if that aircraft is carring 50% the max allowed weight of the standard B737-700.
How much baggage area is left for the use of each of those tanks?
Do the tail and tailwings are used as auxiliary tanks too?
Could a ER version of their B737-600 and 900 (better call it XR for the -900) be feasible too?
Thanks,

I don't think a 900 XR is possible... the "big" wing and whatnot is already used. A -600 I could feasibly see, but then again nobody wants the -600 to begin with because of CASM concerns.

Perhaps someone should tell Westjet, they have quite a few with more to be delivered  Smile



The glass isn't half empty, or half full, it's twice as big as it needs to be.

Ok, "almost nobody."

I mean a -900 with extra fuel tanks, just like a BBJ.

Well, Boeing has already launched the 739ER with increased fuel capacity, takeoff weights and more exit capacity allowing for more max capacity. I suppose you could tank up a -900 further, but you would have to make sure you didn't run into the same problem Airbus had with putting the ACT into the A320

What problem has Airbus got with putting in the ACT's into A320? They are the identical ones to the A319. So fit in quite nicely.
And the A321 has got ACT's too.

Or are you talking about that the A319 with ACT's have got lower MTOW and the A321 has got larger cargo capacity?

The increased fuel weight increased fuel burn almost on a 1 to 1 ratio... therefore at the end of the day you didn't get any significant extra range.

Have Boeing released the range for the 700ER without the auxiliary tanks?

With the increase of the takeoff weights could we expect a range gain for the ER without the need for extra tanks?

I would expect the B737-700ER using no auxiliary tanks to have about the same range as an standard B737-700.
