can 747 fly with 2 engines

A 747 can fly on just 2 engines. A 757 can fly on 1. A 747 cannot takeoff with just two engines because the time it would take to pick up enough speed would have it half way there, but once its in the air, they'll keep it moving. 2.11-Mar-2000

Can a 747 takeoff on 2 engines?

A 747 cannot takeoff with just two engines because the time it would take to pick up enough speed would have it half way there, but once its in the air, they'll keep it moving. 2. If these two engines were on the same side, it would take everything but the galley sink to keep the airplane from turning.11-Mar-2000

How many engines can 747 fly on?

The Boeing 747 is a large, wide-body (two-aisle) airliner with four wing-mounted engines. 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.

Is a 2 engine 747 possible?

Question: If two engines on the same wing of a 747-400 fail, can the jet fly on the other two? Answer: It depends on the weight and the altitude. At very heavy weights and high altitude, maintaining altitude on two engines may not be possible. At lighter weights, it may be possible to maintain altitude with 2 engines.Question: If two engines on the same wing of a 747-400 fail, can the jet flyjet flyThe turbojet is an airbreathing jet engine, typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor).https://en.wikipedia.org › wiki › TurbojetTurbojet – Wikipedia on the other two? Answer: It depends on the weight and the altitude. At very heavy weights and high altitude, maintaining altitude on two engines may not be possible. At lighter weights, it may be possible to maintain altitude with 2 engines.13-Oct-2013

Can a 747 fly with 2 GE9x engines?

In theory yes, but with less cargo capacity and a lower MTOW as the engines are less powerful. However in reality a 747 will never fly with two engines because the airframe and the wings are not designed for it. Two GE9x actually weigh as much or more than four of the original engines.24-May-2018

Can a 747 fly on two engines?

To turn a B747 from a four-engine aircraft to a two-engine aircraft, you'd have to install engines that are powerful enough that the plane can take off using only one of them. (One of the certification requirements for any multi-engine airplane is the ability to take off safely with one engine out.)

How many engines can a Boeing 747 fly on?

The same can be said about the Boeing 747. It has 4 engines because it needs them for its optimal performance. However, from safety point of view, it is not that dangerous if one engine stops working. In fact, that has happened several times.29-Sept-2018

Can B747 fly on 2 engines?

Basically it is a requirement for certification, that a B747, A380 or A340 is still flyable with two engines off.09-Jan-2019

Can a 747 fly on three engines?

Despite the fact that a 747 is unable to fly with three engines, we can see that a single engine would at least extend the aircraft's flight time and extend its distance.07-Jan-2022

Does a 747 have 5 engines?

Despite being built many decades ago, it has kept up with the times and shaped modern aviation. One unique feature of the Boeing 747 is its ability to fly with five engines.18-Aug-2020

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.05-Jan-2021

Can a Boeing 747 take off with one engine?

There are only two engines in a 747. One can fly on a 757. Due to the time it would take to pick up enough speed to take off with just two engines, a 747 cannot take off with just two engines, but once it is in the air, it will keep going.07-Jan-2022

Could the 747 have 2 engines?

Can 747 Be Built With 2 Engines? There are only two engines in a 747. One can fly on a 757. Due to the time it would take to pick up enough speed to take off with just two engines, a 747 cannot take off with just two engines, but once it is in the air, it will keep going.01-Dec-2021

How many engines does a 747 need to take off?

Four engines were needed to power the 747, which is heavy and has a large carrying capacity. In addition, they were required for long ocean flights to ensure that the aircraft could make landfall if an engine failed.07-Jan-2022

How Long Can A Commercial Jet Fly With One Engine? During a total engine failureengine failureA turbine engine failure occurs when a turbine engine unexpectedly stops producing power due to a malfunction other than fuel exhaustion. It often applies for aircraft, but other turbine engines can fail, like ground-based turbines used in power plants or combined diesel and gas vessels and vehicles.https://en.wikipedia.org › wiki › Turbine_engine_failureTurbine engine failure – Wikipedia, a passenger jet can travel for up to 60 miles. The following example shows how to do this. It is typical for commercial aircraft to have a lift to drag ratio of around 10.07-Jan-2022
