Can a 747 fly on 2 ge90 engines?

Two of the 90-115 also have more takeoff thrust (~230k lbf) than the original 747-100 (~175-205k lbf). So, in theory, two modern engines can power a 747, but only the original, not the 747-8. Twins have higher thrust requirements, as they have to be able to take off with just one engine, while quads can use three.

Yes, it's cleared to take off with three and fly with two engines.

The 747 is certified to fly on just three engines, and there was no indication of any damage to the aircraft's other engines. Safety experts and aviation regulators still questioned the decision to operate such a long flight with one engine out.

A twinjet or twin-engine jet is a jet aircraft powered by two engines. A twinjet is able to fly well enough to land with a single working engine, making it safer than a single-engine aircraft in the event of failure of an engine. Fuel efficiency of a twinjet is better than that of aircraft with more engines.

The Boeing 747-400 experiences the least degradation in performance, making it safer during an engine failure. Fitting an aircraft with four engines also increases power, enabling more passengers, heavier payloads, and increased performance.

The Boeing 747 is not the only aircraft that can fly with five engines, however. In fact, several older planes, such as the DC-8 and 707, used to have fifth pods installed to transport spare engines.

MORE DETAILS

One of the unique features of the 747 was its fifth pod. This 'spare' engine mount gave it the ability to lug along an extra engine, something it was capable of doing even on a revenue flight. Of course, the efficiency of the flight would take a hit, but reportedly there were no issues with handling as a result.

Built in 1967 to produce the mammoth jet, it remains the world's largest manufacturing plant according to Boeing. But after five decades, customer demand for the 747 eroded as Boeing and Airbus (AIR.PA) developed more fuel efficient two-engine widebody planes.

Because of aerodynamics, the cockpit level had to rise and slope back down to the main fuselage, giving us the iconic hump.

Boeing 777-9 Boeing's 777-9 is the world's largest and longest twin-engine commercial aircraft. Once it goes into service, the 251-foot-long aircraft will ferry up to 425 passengers on long-haul flights—spanning up to 7,285 nautical miles—around the world.

In theory, having multiple engines should increase safety. If one engine fails, the other can help get you safely back to the ground. But don't let this fool you. Engine failure in a multi-engine airplane can lead to complex situations that require advanced pilot skills.

For example, with a glide ratio of 15:1, a Boeing 747-200 can glide for 150 kilometres (93 mi; 81 nmi) from a cruising altitude of 10,000 metres (33,000 ft).

Dassault Falcon 900EX. The 900 and its derivatives, the Falcon 7x and 8x, are the only trijets in the world currently in production. One consideration with trijets is positioning the central engine. This is usually accomplished by placing the engine along the centerline, but still poses difficulties.

MORE DETAILS

While the Boeing 747 carries more passengers and has a longer range, the 777X surpasses it in cargo capacity and fuel efficiency. The cost of operating the 777X is lower than the 747 due to newer technologies and larger engines, making it a better long-term investment for airlines.

Its wings have a high sweep angle of 37.5° for a fast, efficient cruise speed of Mach 0.84 to 0.88, depending on the variant.

Yes, you can fly on one engine. That's a big reason why they have two. A King Air 200 will fly on 1 engine, but it won't fly on 3.
