Boeing 747-400/Top speed
How fast is a 747 in mph?
The top speed of the Boeing 747 itself is about 570 mph, and this flight maxed out at 825 mph The difference between “ground speed” (zero bonus) and “air speed” (200+ mph bonus) is also why this speed, while technically faster than the speed of sound, didn’t ever go supersonic
How fast does a 747 cruise at?
Answer: The Boeing 747 can cruise at 92% of the speed of sound, Mach 92 It is very rarely flown at this speed due to the increased fuel burn required Most modern jets fly around 80% of the speed of sound, Mach
What is the fastest a 747 can fly?
The 747 is one of the largest commercial aircraft ever built, and the 747-8 Intercontinental (747-8i) variant wins the race as the fastest commercial plane in service today This plane is as tall as a six-story building with a top speed of Mach 086 That’s equivalent to 65985 mph
How fast does a 727 go to take off?

Can a 747 do Mach 1?
4 Answers No The Boeing 747 was not designed for supersonic flight, though during testing, it was pushed quite close to the sonic speed: Tom Cole, a spokesman at Boeing Commercial Airplane Co, said original flight tests of 747s conducted in 1969 and 1970 took 747-100 models to speeds of Mach 099
Can a 747 take off with 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
What speed does a helicopter fly at?
An average helicopter can reach a top speed of somewhere between 130 and 140 knots, which comes out to about 160 mph The Eurocopter X3 can reach a top speed somewhere in the neighborhood of 267 mph (430 km/hr or 232 kts) in stable and level flight
Is a 747 a jumbo jet?
The 747 was the first quad-jet engine and dual-level passenger aircraft to roam the skies It’s known by many names including Jumbo Jet, Queen of the Skies, and even the Humpback, and is arguably the most recognizable aircraft ever built
Which one is bigger 747 or 777?
Summary The 777 is both longer in length than the 747, as well as having a longer wingspan No surprisingly, the 777 is shorter than the 747, however, it isn’t as short as you’d expect, it’s only three feet shorter
What’s the slowest speed a plane can fly?
Technically this is the so-called ‘stall speed’, where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph)
How fast are military jets?
The F-15 has been flying for more than 30 years and is set to keep going The reason is just good design, another aircraft initially designed to catch incoming enemies and destroy them The F-15 can fly at a top speed of 3,017 miles per hour, then stop, hit ground targets, and fade away
How fast does a Boeing 777 fly?
Plane facts and figures Aircraft type Speed in km/u* Altitude in ft* Boeing 737 850 35,000 Boeing 777 905 35,000 Boeing 787 Dreamliner 907 40,026 Embraer 190 829 39,370
How fast does a 737 fly in mph?
The advanced wing airfoil design provides an economical cruise speed of 789 Mach (530 mph) – compared to 745 Mach for earlier 737 models The Next-Generation 737 airplanes are capable of cruising to a maximum altitude of 41,000 feet, compared to 39,000 feet for the competition
Did the 747 break the sound barrier?
As it shot across the Atlantic, the Boeing 747-400 jet reached a top ground speed of 825 mph However, the jet did not actually break the sound barrier, because that is measured by its airspeed, or the speed of the plane relative to the air through which it is traveling
Can passenger jets fly upside down?
The answer is yes for a “little” bit! Unlike military fighters, commercial planes do not have the engine power for sustained inverted flight and rely on lift from the wings Commercial airliners are only tested and certified for upright flight” However, one Boeing aircraft has flown upside down – twice!Jun 18, 2020
Why is a sonic boom two bangs?
The “boom” is experienced when there is a sudden change in pressure; therefore, an N-wave causes two booms – one when the initial pressure-rise reaches an observer, and another when the pressure returns to normal This leads to a distinctive “double boom” from a supersonic aircraft
Who owns the most Boeing 747?
Plenty of airlines are synonymous with the Boeing 747, but the world’s biggest operator of all time might well surprise you The airline that has operated the most 747s ever is not Singapore or Pan Am, or even British Airways… it’s Japan Airlines Since the 1970s, JAL has operated a total of 108 Boeing 747
Can a 747 back up?
no one ever does Some aircraft can do a so-called ‘powerback’, but in most cases, airplanes either don’t have this technical capability Most airplanes can taxi backwards by using reverse thrust This entails directing the thrust produced by the plane’s jet engines forward, rather than backwards
Why does a 747 have 5 engines?
The extra engine adds drag to one side of the plane Consequently, pilots have to adjust the power on the other side to compensate The special cargo meant that the aircraft was heavier and required additional stops
