Re: Business Risk for Boeing: The A321XLR

If one compares the cross section of 7 abreast economy B767 with 6 abreast economy A321, the B767 has no chance. If one compares the cross section of 1-2-1 business of a B797 with a 1-2-1 business of a B787/ A350, the B797 does quite well. To follow RJMAZ, maybe the two main advantages of the B797 ...

My point on J is not irrelevant, since an airline operating A321 will be able to pack lie flat seating into much smaller real estate than an airline operating widebody. It is irrelevant. The lie flat J seat is the same size regardless of aircraft. It does not become smaller on a single aisle. Ameri...

Re: What does the Rumored 6T MTOW Increase for the 787-10 Mean for the A359?

So with this stunning 6t MTOW increase will the landing gear crumble at the gate and everybody will laugh or at V1? As many have said landing weight would be the same. So the max load on the landing gear would be unchanged. There is very little load on the landing gear when stationary at the gate. ...

Re: Updated: Qantas saying it is almost ready to select Project Sunrise aircraft

Take any payload range chart from the 777, A350, 787, A340 and pick the worst one with the steepest gradient. Even using this worse case gradient the 8690nm easily exceeds the Sydney-London route. So my firm conclusion is completely supported. On that basis I don’t know why airlines even bother wit...

Re: Updated: Qantas saying it is almost ready to select Project Sunrise aircraft

If the 777-8 can fly 8690nm with 365 passengers and we use the gradient of the 787 payload range curve then it would fly 9500nm with 265 passengers. So it can easily do Sydney to London completely standard. You can't just use data from the 787's performance and extrapolate to the 777x and then conc...

Re: Updated: Qantas saying it is almost ready to select Project Sunrise aircraft

Isn't the 8690 nmi range is inaccurate and Boeing will revise it to be 9500 nmi? 9500 nmi will certainly be more than enough for Project Sunrise. There is no way the 777-8 will be able to be revised to fly 9500nm with the 365 passengers. All aircraft fly further when you have less payload (passenge...
