This means that it can cover a distance of around 4,700 miles in a single day of flying. The 747 is one of the fastest commercial aircraft,and its speed is a big part of what makes it so popular with airlines.
What is the maximum speed of a Boeing 747?
The 747–400 is certified by the FAA and other agencies eg EASA (European Aviation Safety Agency) to fly at up to Mach 0.92 and at heights depending on the variant up to about 45,000 ft. So the maximum legal speed above 35,000 ft. is about 607 mph.
What is the maximum airspeed of a Boeing 747?
There are many variants of the Boeing 747, so it varies a little. The maximum speed is around Mach .89 to .92 at higher altitudes, while at lower altitudes, it is limited by indicated air speed (normally 365, but again it varies and I don’t remember the 747 Classic limitation any more, maybe 360?)
What is the size of a 747?
To sum it up, depending on the variant, a Boeing 747 aircraft is anywhere between 184 feet 9 inches (56.30 meters) and 250 feet 2 inches (76.25 meters) long. While there are slight differences in the tail height of the different 747 variants, the differences are minor. More specifically, they are smaller than 25 inches.
Why is the 747 so rarely flown?
Q: There’s a lot of coverage about the inevitable death of the 747 because it is too costly to operate a four-engine aircraft.
How many engines does a 777 have?
A 777 engine may be equal to two 747 engines, but the wing is not designed to take such a large engine in one place. The 747 originally flew in 1969; in those days it took four engines to power it. Therefore, the design was centered on four engines.
Why are large airplanes so difficult to sell?
Large airplanes are very difficult to sell because of the high initial cost and high cost of operations. Twins like the B777 and A350 provide more economic operations. Q: It saddens me to see the near-disappearance of the Boeing 747 from active duty. I have always thought of it as the most beautiful aircraft.
Is the 747 a twin engine?
Since then, engine technology has improved, making more powerful engines common. However the design limitations remain for the 747. The 777, a twin engine airplane, can fly almost as many people, almost as far as a 747, but it was designed thirty years later.
Can you reengine a 747 to a twin?
It may be possible to re-engine a 747 to a twin but I have not heard of an economical way.
What speed does a Boeing 747 land at?
A 747 ‘Jumbo Jet’ would typically land at a speed of about 145kts-150kts (166mph-172mph), depending on the landing flap setting selected.
What is the flap setting on a jumbo jet?
The greater the flap setting, the lower the take-off and landing speed. Jumbo Jets typically land at Flap 25 or 40. Pilots generally fly the approach speed faster than the actual touchdown speed to allow a speed ‘buffer’ in case of any airspeed fluctuations.
How fast does a 747 take off?
What speed does a Boeing 747 take off at? A fully loaded Boeing 747 ‘Jumbo Jet’ on a normal long haul flight would take off at a speed of around 160 knots which is 184 mph. The calculated take-off speeds vary depending on environmental conditions, runway length and weight.
Why is it important to take off with reduced thrust?
Taking off with reduced thrust reduces the temperature the various components in teh engine are exposed to. This in turn can significantly reduce engine wear and tear and thus maintenance costs, and ultimately extend the life of the engine.
Do commercial planes need full engine power to take off?
This occurs on runways where the aircraft has extra performance in hand e.g. the aircraft does not need the full length of the runway to take-off. Large commercial aircraft rarely use their full engine power for take-off as most runways at large airport long enough to support a reduction in thrust. Take-off thrust might be as little as 75% …
How many 747s does Lufthansa have?
Transatlantic travel on the jumbo jet isn’t over, though. Lufthansa has 10 747-400s and 19 747-8s in its fleet. A spokesperson said the German flag-carrier continues to operate the aircraft on routes in North America, Asia and other long-haul destinations.
What was the 747 designed for?
The 747 was designed at a time when the airline industry expected the supersonic transport — SST for short — to be the aircraft of the future.
What was the first plane to have a vertical sidewall?
The interior of the 747 was developed in association with the Seattle-based firm Teague, Boeing’s long-time cabin design partner. It was the first plane to have almost vertical sidewalls and a high ceiling, giving passengers a feeling of space and openness.
How wide is the 747?
The main deck of the 747 was sized about 20 feet wide, to handle two standard cargo containers. To make loading easier, the nose of the cargo model of the 747 opened and pivoted upwards. That meant that the cockpit had to be located above the main deck, giving the Queen its distinctive hump just behind the flight deck.
How many hardy 747s have been made?
As for the hardy 747, more than 1,500 of them have been manufactured over the past half-century.
When did the 747 first fly?
The first Boeing 747 made its maiden flight on February 9, 1969, a year before entering service with the fondly remembered airline Pan American World Airways.
Is the 747 turbofan engine reliable?
And instead of the scream of earlier generation jets, the 747 "buzzed" when it took off. The 747 might have been the first, but now every passenger jet is powered by an incredibly reliable and sophisticated high-bypass turbofan engine.
What is the most iconic aircraft in the world?
by Jay Singh. September 8, 2019. 3 minute read. The Boeing 747 is one of the most iconic of aircraft in the world. With over 50 years since its first flight, the jumbo jet has gained a significant fan following amongst aviation geeks and passengers alike.
Why was the 747 so popular?
On the airline front, the 747 allowed for airlines to have a much more global footprint. Pan Am, in particular, was iconic for flying their 747s to new and far-reaching destinations. And, due to the four engines, the aircraft was more reliable. At the time, twin-engine aircraft were not allowed to cross the Atlantic.
What is the 747 known for?
The 747 was well-known for the amount of space on board the aircraft. As the largest jet by passenger capacity at the time of its launch, the aircraft still offered room to move around and stretch about. On the 747, space and comfort were not much of an issue. Photo: Boeing.
What is the legacy of the 747?
However, as airlines seek to move beyond the foundations set up by the 747 to new and improved aircraft like the 777X, it is clear that the legacy of the aircraft will endure for many years to come.
What is the 747?

How long is the runway on a Boeing 747?
The original design of the Boeing 747 requires a minimum runway length of 7500 feet or 2200 meters. But this depends on a number of factors, including the aircraft weight, airport elevation, temperature, wind speed, and much more.
Why is takeoff speed calculated before every takeoff?
Due to weather conditions, altitude, the type of aircraft, and other factors, a unique takeoff speed is calculated before every takeoff.
How much runway do private jets need?
Comparably, commercial aircraft require significant runway space to take off or land, typically a minimum of 4,500 feet and a max of up to 13,000 feet or more. The harsher the weather and thinner the air, the longer the runway needs to be for a safe take off and landing.
