Yes, it's cleared to take off with three and fly with two engines.Conclusion. While it's very clear that a 747 cannot fly properly with the failure of three engines, we can see that a single functioning engine would at least extend the aircraft's distance and prolong its time in the air.Without engine thrust, the 747 had a glide ratio of 15:1, meaning it can glide forward 15 kilometres for every kilometre it drops. After calculating the glide ratio, the crew realized that they had less than 30 minutes to regain power before they smashed into the ground.
Can a 747 take off with three 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.
Are 2 engine planes safer
There is a fair argument that multi-engine piston aircraft are safer than single-engine piston aircraft. In theory, they are. But this only holds true if the pilot has the skill to efficiently handle an engine failure in a multi-engine aircraft. Interestingly, modern single-engine turboprops are quite reliable.
Why does the 747 need 4 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.
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). On 24 June 1982, the route was flown by the City of Edinburgh, a Boeing 747-236B registered as G-BDXH. The aircraft flew into a cloud of volcanic ash thrown up by the eruption of Mount Galunggung around 110 miles (180 km) south-east of Jakarta, Indonesia, resulting in the failure of all four engines.
Can a 747 taxi on one engine
Although i have seen the 747 taxi with number 3 shutdown. Yes you can! I too generally use only a single engine for taking if it is a long way to the RWY. Captain Joe did a good video on single engine taxi.The aircraft doesn't have to lose altitude particularly rapidly to keep flying and therefore if both engines were to fail a high altitude, the aircraft may have as much as 20 – 30 minutes of airbourne time to find somewhere to land before it reaches the ground.A fuel leak or running out of fuel will cause both engines to fail. Air Transat 236 ran out of fuel due to a leak approximately 65 miles from the Azores in 2001. The pilots successfully managed to glide the aircraft to an airbase on the island. Finally, the chances of something going wrong on a twin engined aircraft vs a quad are higher for the quad because it is a much more complex system. So yes, if an engine fails a four engined plane would be able to deal with it better but the chances of something going wrong are twice as high.

But this only holds true if the pilot has the skill to efficiently handle an engine failure in a multi-engine aircraft. Interestingly, modern single-engine turboprops are quite reliable.
Can a 747 glide with no engine : Any plane can glide if its engines fail, with the distance and time it can glide depending on its altitude at the time of engine failure and its design characteristics.
Will a 747 or 777 glide if it loses engine thrust
Any plane can glide if its engines fail, with the distance and time it can glide depending on its altitude at the time of engine failure and its design characteristics. First of all, the Boeing 777 is designed and certified to fly with only one engine for up to five and a half hours. This means that the pilot has more than five hours to find the nearest suitable airport to land safely.That rule ensures that even if one engine goes down – as appears to have happened here – the plane can still arrive safely. It can fly until it runs out of fuel. Basically, these planes are built to fly as well on one engine as they can on two.
