Re: Boeing 737MAX Grounded Worldwide Q3 2019

Is there any indication that there is consensus between EASA and the other certification authorities in the world?

At the moment it looks like EASA in the only agency making any noise about the matter.

Re: Rumor: Airbus to launch A350-1000ULR

I would imagine that any stretch of the A350-1000 will only come when the Neo is announced - that means 2025 or later EIS. Development and flight tests will take time and it is best that Airbus used this time (waiting for RR's UltraFan to be ready) wisely and developed the stretch carefully. I wond...

The problem with the LR was the MZFW. payload is around 22t and the ACT and its fuel eats in to the payload capability of the aircraft
I wonder if the fuel in the RCT is regarded as fuel in center and wing tanks in performance calculations, and therefore leaves the 22t payload capability unaffected.
