No again you are oversimplifying. The -800 or whatever standard of aircraft you chose to startSD67 wrote: ↑08 Nov 2023, 17:52That's interesting, so we now have a new breed of CADCAM that magically self destructs after a decade. All that integration work somehow disappears into the ether.SW1 wrote: ↑08 Nov 2023, 17:40Yes Australia did buy the bbj variant they also have 2 leased for government transport. They haven’t made them for some time. I believe all the wedgetails converted were from this baseline standard. Boeing moved on to the -800ng bbj sometime in the late 2010s and stopped making them all together in 2021 as they moved to max.SD67 wrote: ↑08 Nov 2023, 17:12 Right so as a cost accountant that is exactly what I would be challenging. What exactly is needed? Give me the specific dimensions. Payload endurance aerodynamic performance. Then gap fit that against the documented performance of this brand new 737 I have just bought from Ryanair. What is the cost of the delta. What are the alternative uses for that cost. Did Australia buy some special BBJ variant? If not why not. If the E7 cannot be easily adapted to a baseline 737 NG then it is not very good is it and actually maybe the advertised price is not entirely representative of the true acquisition cost - would you like us to advertise that to the entire world?
Seriously a Boeing sales rep walks in, sees one of our guys and has to contain himself from bursting out laughing.
It’s a -700 fuse with a strengthened wing, 6-9 Additional fuel tanks and strengthened landing gear. That’s before the conversion is to begin.
All non recurring engineering and integration of systems would would need to be re-done against a new baseline if you don’t wish to use the same variant as previous or you wouldn’t be able to certify it.
Ryanair buy the most consessed aircraft going form Boeing that no one else wants so they get them cheap wouldn’t start from there.
And we have certification that expires despite the fact that a the exact same airplane is currently in service with one of our closest allies. Really interesting. Let's test this out, get a friendly billionaire, say I don't know call him "Trump" to call up Chicago and ask for a BBJ -700 NG with a new wing, see what they say.
with is a different standard to that which the original baseline engineering is against and also at a different effectivity. This can also be a problem if tail numbers your converting cross mod cut ins in the production run. The RAF like all there aircraft as far as possible at the same mod standard before conversion this happened on sentinel and required some aircraft to be de moded before that started. It should also be noted that the MAA have not certified a Boeing E7 before and given Boeing recent history will do it rigorously at 2023 standards they maybe less willing to grandfather certain things
You can get Boeing to make whatever you wish and pay what there asking if you have the budget.
