How fast is a 747 going when it touches down? (2024)

How fast is a 747 going when it touches down?

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.

How fast is a 747 going when it lands?

A Boeing 747 aircraft has a landing speed of 72 m/s, and upon landing it is able to come to a stop in 2,000 m.

How fast is a plane going when it touches down?

Approximately five minutes before landing, the approach manoeuvre begins, at an average speed of 380 km/h. On the descent path, the aircraft slows down to about 270 to 240 km/h, which is the speed at which the aircraft will safely touch the ground.

What is the touchdown speed of a 747?

Although it varies due to multiple factors, a typical landing speed for a Boeing 747 is around 150 kias, while a typical landing speed for a much smaller and lighter Cessna 172 would be 60 to 70 kias with flaps at 30 percent, according to the pilot operating handbook.

What is a planes speed when it lands?

Takeoff and landing speeds are much slower, typically between 130-180 mph, depending on the aircraft and weather conditions. The landing speed of a commercial airliner can be around 160-180 mph, while the takeoff speed can be around 130-160 mph.

What is the slowest speed a 747 can fly?

The slowest speed at which a Boeing 747 can fly depends on various factors such as its weight, configuration, and weather conditions. However, a typical approach speed for a Boeing 747 is around 140-160 knots (161-184 mph or 259-296 km/h) when landing.

Why do planes speed up before landing?

As the plane descends into ground effect, it may actually accelerate if the engines are producing enough thrust, since in ground effect the plane requires much less power to keep "flying". Power from the engines will translate into speed, if not height.

How high can a 747 fly?

To summarize, a Boeing 747 is incapable of ascending up to 60,000 feet. The highest altitude a commercial jetliner can reach is approximately 45,000 feet, while corporate aircraft can fly slightly above 50,000 feet, but only if they are specifically designed for that purpose.

What happens if a plane flies too fast?

In jet aircraft, an overspeed results when the axial compressor exceeds its maximal operating rotational speed. This often leads to the mechanical failure of turbine blades, flameout and total destruction of the engine.

Why do aircraft fly at 35000 feet?

The biggest reason for flying at higher altitudes lies in fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak.

What is the slowest speed a plane can fly?

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).

What is the landing speed of a 747 without flaps?

A typical landing speed for a 747 is around 145-160 knots, which is equivalent to 166-184 miles per hour.

Why does the 747 fly so fast?

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.

How fast does a plane go on the runway before takeoff?

One common question is, how fast does a plane need to go to take off from the runway? If you're short on time, here's a quick answer to your question: most commercial airliners need to reach speeds of 130 to 180 mph before their wings can generate enough lift for takeoff.

Why do planes not fly at full speed?

Typical commercial airplanes are not designed to fly faster than the speed of sound, also known as Mach 1. If they get too fast, the air begins forming shockwaves along the wing that can cause the aircraft to become uncontrollable.

What is the fastest jet in the world?

1 – NASA X-43

The fastest jet in the world is NASA's X-43 experimental plane. Thanks to its scramjet design it was able to reach a speed of Mach 9.6, or 11,854 Km/h. Three of these planes were built in total.

Could a 747 go supersonic?

This rapid descent resulted in the 747-100 exceeding its maximum speed limit of Mach 0.92. Official reports suggest the aircraft reached at least 0.98 Mach during its descent. However, some reports indicate the plane reached speeds as high as Mach 1.25. Of course, this would put it beyond the supersonic limit.

How many hours can a 747 fly?

This depends on the size of the plane, its efficiency, and how fast it's flying. 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!

What's the fastest commercial plane?

If you're short on time, here's a quick answer to your question: the Boeing 747-8i is currently the fastest commercial jet airliner in service with a top speed of Mach 0. 86. In this comprehensive article, we will dive deep into the details surrounding the fastest commercial planes in operation today.

Why do planes turn immediately after takeoff?

Airplanes turn immediately after takeoff to ensure the safety of passengers and crew. This is done to avoid any potential obstacles or hazards that may be in the flight path, such as tall buildings, mountains, or other aircraft.

Why do planes load front first?

This method allows passengers seated at the front of the plane to board first, reducing the time it takes for everyone to find their seats. Additionally, it helps distribute the weight of the passengers more evenly throughout the aircraft, which can contribute to a smoother takeoff.

Why do planes turn after takeoff?

You may also notice the plane "banking" or turning shortly after takeoff. That's normal, we're just following ATC instructions or turning toward our destination. During takeoff see if you can enjoy the feel of acceleration. These jet airliners have lots of power and can really move!

What plane can fly at 60000 feet?

Concorde (of course, no longer operational) was rated to fly up to 60,000 feet. And many private jets operate up to around 45,000 to 51,000 feet. And if you introduce military jets, the SR71 holds the record (for normal flight) at 85,000 feet. Stay informed: Sign up for our daily and weekly aviation news digests.

What civilian aircraft can fly at 60000 feet?

Concorde SST

The Concorde supersonic transport (SST) was a groundbreaking aircraft that could fly at altitudes of around 60,000 feet.

Why does 747 have a hump?

Trippe was one of Boeing's best customers and usually the first to order new models, so Boeing put the flight deck of the 747 above the passenger cabin to give the aircraft a hinged nose for a front-loading cargo door. The first design for the co*ckpit enclosure was a hemispherical hump atop the fuselage.
