> The question in my mind is, what replaces the 747, and is it safe? Looks like 777X is going to replace 747.
The 747 has been replaced for passenger service for decades. This isn't the first time production has been halted. The 777 has been around since the 1990s. With the 767, 777, and 787 there's really no need for the 747 anymore, especially for passenger service.
> Does the 777X have the same design flaws as the 737 MAX, namely larger engine, positioned forward in way that destabilizes the airframe?
In a word, no.
The 777X looks more like the 737NG vs the 737 Classic. It's stretched and has new wings, but the engines on the 777 were already massive. The 777 started with 330cm diameter engines and the new ones are 335cm. Given the gear arrangement on the 777 I doubt they had to move the engines forward.
Further, the 737 MAX crashes weren't directly caused by moving the engines, it was more caused by MCAS and a lack of training and explanation. Boeing tried to make the 737 MAX feel like a 737NG, but the plane itself wasn't inherently unstable.
The 777X does not have MCAS:
> Boeing stated that the 777X does not have an equivalent of the Maneuvering Characteristics Augmentation System (MCAS) that is installed on the 737 MAX and that played a role in two crashes.
