779X/778X MTOW 775,000 lb, 105,000 lb per engine
A350-1000 MTOW 679,000 lb, 98,000 lb per engine
The A350-1000 has about 6% higher thrust to weight ratio of the 779X/778X, yet it is the one that is under powered ?
You think an aircraft that is 96,000 lb heavier (the empty weight of a 737) might burn just a little more fuel ?
