A versatile unit

Not only can the 747 fly on one engine, but it can also fly on fewer than four in an emergency.Boeing 747: Depending on the specific variant, it can cruise at speeds around Mach 0.85, which is approximately 570 mph (920 km/h) at cruising altitude. Boeing 777: It has a typical cruising speed of Mach 0.84, roughly 560 mph (905 km/h).The stall speed is published as 138 Kts/160 mph, so roughly 20 above that to maintain level flight.

What engine is in the 747-400 : The 747-400 offers a choice of improved turbofans: the Pratt & Whitney PW4000, General Electric CF6-80C2 or Rolls-Royce RB211-524G/H. Its two-crew glass cockpit dispenses with the need for a flight engineer.

Can a 747 have 5 engines

As others have said, by technicality yes. Your 4 main turbofan engines, plus APU. 5 engines total. Add one for transport on the LH wing hardpoint and you're up to 6 engines!

How many engines can a 747 lose and still fly : 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.

These include the Pratt and Whitney pw4000. The Rolls-Royce Trent 800. And the general electric GE 90 engines in contrast the Dreamliner 787 is powered by either the General Electric Gen.

Mikoyan-Gurevich I-350 (1951) (USSR), It was the first Soviet aircraft able to maintain supersonic speed. Bell X-2 (1952) (USA), Rocket powered. SNCASO Trident (1953) (France), French supersonic twin engine research aircraft. Fairey Delta 2 (1954) (UK), first to exceed 1,000 miles per hour.

How many 747s have crashed

Hull-losses:	64
Hull-loss accidents:	52	with a total of 2865 fatalities
Criminal occurences (hull-losses, excl. hijackings):	5	with a total of 857 fatalities
Hijackings:	32	with a total of 24 fatalities
Survival rate:	23.9%	of all occupants survived fatal accidents

Slowest aircraft

The Ruppert Archaeopteryx has a certified stall speed of 30–39 kilometres per hour (19–24 mph). The Vought XF5U can fly as slow as 32 kilometres per hour (20 mph). The Tapanee Pegazair-100 stall speed is 45 kilometres per hour (28 mph).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 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. The sweep also reduces the wingspan, allowing the 747 to use existing hangars.

Can a 747 run on 3 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.

Can a 747 take off with 3 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.

Can a plane land if both engines fail

We all know about the story of US Airways flight 1459 landing in the Hudson River in New York after both its engines were destroyed by birds, but that really was exceptional – and everyone survived thanks to the quick actions of the actions of the pilots Captain Chesley Sullenberger ('Sully') and First Officer Jeffrey …

The Airbus A380 can reach speeds of more than 1,000 kilometres per hour! Now the Boeing 787 Dreamliner (907 km/h) and Boeing 777 (905 km/h) aren't that fast, but still three times faster than a Formula 1 racing car. See below the speeds of the most common aircraft on Schiphol.The 777-9 is the largest of the two widebody families, boasting a length of nearly 252 feet and space for up to 426 passengers in two classes. The Airbus A350 follows at about 242 feet, then the 777-8 at 232.5 feet. The A350-900 is the smallest of the four at just over 219 feet long, according to the planemaker.

Can a jet go 5000 mph : Flying faster than any other aircraft ever built, NASA's X-43A “Hyper X” plane reached a top speed of about 5,000 mph, or about a mile and a half per second, before being intentionally ditched in the ocean.
