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?
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
