A modern Boeing 747 can fly about 15,000 km (9,500 miles) when it’s flying at 900 kmh (550 mph). This means it can fly non stop for almost 16 hours!
How long can a Boeing 747 stay in the air?
On average, an aircraft is operable for about 30 years before it has to be retired. A Boeing 747 can endure about 35,000 pressurization cycles and flights—roughly 135,000 to 165,000 flight hours—before metal fatigue sets in. 747s are retired after approximately 27 years of service.
How far can a 747 go on a tank of fuel?
The four engines of the Boeing 747 Jumbo Jet burn approximately 10 to 11 tonnes of fuel an hour when in the cruise. This equates to roughly 1 gallon (approximately 4 litres) of fuel every second. It can carry a maximum of 238,604 liters of fuel and it has a range of about 7,790 nautical miles.
What is the maximum range of a 747?

How fast is a 747 going when it leaves the ground?
The 747 goes from its approximate takeoff speed of 200 mph (89.4 meters per second) to 0 mph in 27 seconds.
How much does it cost in fuel to fly a 747?
The cost to fuel a plane largely depends on local fuel prices and the supply of crude oil. Going by averages, it would cost between $170,000-$200,000 to fuel a Boeing 747-8. The Airbus A380-800 costs more at $230,000-$260,000 to fuel.
How much is a gallon of jet fuel?
As of the beginning of 2022, on average, Jet A fuel costs $5.29 per gallon.
How much fuel does a 747 burn compared to a car?
That means the plane is burning 0.01 gallons per person per mile. In other words, the plane is getting 100 miles per gallon per person! The typical car gets about 25 miles per gallon, so the 747 is much better than a car carrying one person, and compares favorably even if there are four people in the car.
How much fuel does a 747 burn an hour?
Boeing 747 fuel consumption
If an Airbus A321neo burns 0.683 litre per second, Boeing 747 uses approximately 4 litres every second, which translates to 240 litres per minute and 14,400 litre per hour.
Can a 747 land with full fuel?
Larger planes like the Boeing 747, on the other hand, have fuel jettison systems. If the aircraft tried to land without dumping the fuel first, it is considered an overweight landing attempt and could place immense stress on the airframe.
Can a 747 land on autopilot?
The 747 can land itself. The 747 is certified to conduct autolands to CAT IIIB requirements. The 747 does have ‘flare’ and ‘rollout guidance’ – where the 747 will reduce the rate of descent just before touchdown, and rollout guidance allows the autopilot to maintain the runway centreline after touchdown.
Can a 747 land anywhere?
The even longer answer: Not a chance. Minimally, a 747 would need thousands of feet to land, even in an emergency… As a perspective, a 747 is depending, upon the model, is around 250 feet long or longer while an American football field is 300 feet long.
How long can a 747 fly without engines?
A passenger jet could glide for up to about 60 miles if it suffers a total engine failure at its cruising altitude.
How long of a runway does a 747 need to land?
The chart notes that if a Boeing 747-400 had an operational landing weight of 475,000 lbs (215,456 kg) and wanted to land at a runway located at sea level, then the suggested runway length would be a little over 1,500 meters, or roughly 5,000 feet.
Has a 747 ever landed on water?
4 November 1993: China Airlines Flight 605, a Boeing 747-409, ended up in water after it overran runway 13 at Kai Tak International Airport on landing during a typhoon with wind gusting to gale force. All of the 396 occupants donned life-vests, boarded the eight slide/rafts and no fatalities resulted.
How fast is a 747 at cruise?
It has a pronounced 37.5° wing sweep, allowing a Mach 0.85 (490 kn; 900 km/h) cruise speed, and its heavy weight is supported by four main landing gear legs, each with a four-wheel bogie.
Why do planes not freeze in the air?
If it drops below the dew point, dew forms; if it drops below that and freezing, frost forms. In flight, the high speed air flow over the aircraft keeps its skin at essentially the same temperature as the air so it doesn’t drop in temperature the same way.
How much profit does a flight make?
According to the Wall Street Journal, the average “profit per passenger” of the seven largest U.S. airlines was $17.75 — for just a one-way flight — and the average profit margin across those seven airlines was 9% in 2017.
How long does it take to fill a 747 with fuel?
It takes about 45 minutes to one hour to fuel the aircraft, and the process begins no later than 90 minutes before the flight.
What octane is jet fuel?
The octane ratings of AVGAS, a gasoline-based fuel, are usually either 91 or 100 (lean mixture) and 96 or 130 (rich mixture). The octane rating of jet fuel is much lower, around 15 – this is much more like automotive diesel and thus much more resistant to detonating due to sparks or compression.
Can you put jet fuel in a car?
Jet fuel can actually be used in cars, but only in diesel engines. Kerosene jet fuel and diesel are actually similar enough to allow for cross-functionality and would provide a similar performance. Although, I wouldn’t recommend running a jet on diesel.
