With a cruise TSFC value of 0.520 for the 777's GE90-85B2, the thrust can be anywhere between 18,300 and 8,600 lbf, per engine.

The Boeing 777 is the best-selling long-haul carrier in the history of aviation. It has an exceptional life-span of 30 years, but what's the secret behind this record-breaking longevity? In this film, a 777 is taken apart, inspected, and entirely refurbished.
We have made it clear that the Boeing 777 can actually fly with one engine without much trouble. Whether it is fuel starvation, the fan blades, or any mechanical failure causing the engine to fail, if any of the jet engines fail, the remaining engine can help the plane fly safely.
All fixed-wing aircraft have some capability to glide with no engine power; that is, they do not fall straight down like a stone, but rather continue to glide moving horizontally while descending.
Early jet enginesBoeing's first 747 jumbo had much bigger engines which produced about 45,000lbs of thrust. The most recent model, the 747-8, has engines that produce 66,000lbs of thrust.
The most powerful aircraft in terms of thrust is currently the Antonov An-225 Mriya, a Ukrainian cargo plane. The An-225's engines generate a total of 332,750 pounds of thrust, making it the most powerful aircraft in the world. T/W ratio depends on: altitude.
The Boeing 777-200ER take off or rotate speed (VR) typically occurs between 130 – 160 knots (roughly 120-180 mph) depending on the weight of the aircraft. At a typical take-off weight of around 230,000 kgs, the take off speed would be approximately 145 kts which is approximately 165 mph.
The reason planes cruise at high altitudes is that they burn less fuel and can fly faster, as the air is less dense. At 30,000 feet and higher, it is also possible for aircraft to avoid weather systems, making it more comfortable onboard.
The trijet 777 was later dropped, following marketing studies that favored the 757 and 767 variants. Boeing was left with a size and range gap in its product line between the 767-300ER and the 747-400.
The Boeing 777-200LR holds the world record for the longest non-stop flight without refueling with a flight distance of 11,664 nautical miles (21,601.7 km). The 777-300ER, which is the most popular variant, has a range of 14,490 kilometers (7,825 nautical miles).
