How far can 747 glide?

For example, with a glide ratio of 15:1, a Boeing 747

Boeing 747

The Boeing 747 is a large, long-range wide-body airliner designed and manufactured by Boeing Commercial Airplanes in the United States between 1968 and 2023. After introducing the 707 in October 1958, Pan Am wanted a jet 21⁄2 times its size, to reduce its seat cost by 30%.

Boeing 747 - Wikipedia

-200 can glide for 150 kilometres (93 mi; 81 nmi) from a cruising altitude of 10,000 metres (33,000 ft).

How far can a 747 glide without power?

Answer: It would vary depending upon the wind, but around 100 miles would be a good estimate.

How far can a 747 glide without engines?

A passenger jet could glide for up to about 60 miles if it suffers a total engine failure at its cruising altitude.

Can a 747 glide to land?

With all four engines not functioning, the aircraft began to glide down toward the earth. Thankfully, one engine eventually regained function as the plane descended. While this wasn't enough for the aircraft to gain altitude, it was helpful in slowing its descent.

How far can a 747 glide from 40000 feet?

He continued: 'So at 40,000ft cruise altitude the range of the aircraft to touchdown is about 80 miles.

How far can airplane glide?

Can a 747 land on 5000 ft runway?

Can a 747 land on a 5000 foot runway? Yes, but only if it has an operation landing weight of no more than 475,000 pounds and the runway sits at sea level.

What is the best glide speed for a 747?

Speed to Fly

Also, a 747 has a better glide ratio than a Bonanza, but to do so it must be going almost 300 knots.

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.

At what speed does a 747 leave the ground?

A Boeing 747 under standard conditions must be going 296kph (184 mph) to take off. Additionally, weather factors can affect the ground speed need for takeoff. For example, a headwind will reduce the ground speed needed.

What is the maximum height a 747 can fly?

Boeing widebodies

Lufthansa previously bragged that its 747-400 could reach the highest altitude in its fleet, with a maximum service ceiling of 44,947 ft (13,610 m). The German flag carrier also flies the modern 747-8, which has a service ceiling of 43,100 ft (13,137 m).

How much fuel does a 747 burn per mile?

A plane like a Boeing 747 uses approximately 1 gallon (about 4 liters) of fuel every second. Over the course of a 10-hour flight, it might burn 36,000 gallons (150,000 liters). The 747 burns approximately 5 gallons of fuel per mile (12 liters of fuel per kilometer).

How much fuel does a 747 burn per second?

While several more fuel-efficient aircraft are traversing the skies today, a Boeing 747 quadjet burns up to one gallon of fuel every second. Every. Second. That means that during a five-hour flight, a Boeing 747 will burn 18,000 gallons of fuel.

How far can a 747 fly on one tank of gas?

How far can an airplane go on a full tank of fuel without stopping while travelling at a constant 15,000 feet above sea level? A: 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).

What speed 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 .

Do planes glide if engines fail?

Airplanes Can Glide After Engine Failure

Even if some or all of an airplane's engines fail, it can still safely glide while descending in preparation of an emergency landing. An airplane won't just drop to the ground after its engines fail.

Can a 747 reverse on the ground?

News Across the U.S.

Direct answer to your question: No, the engines do not reverse. However, there is thrust reverse on most jetliners to help the deceleration by this deflected air.

How fast does a 747 go before takeoff?

How Fast Does a 747 Go To Take Off? A typical takeoff speed for a Boeing 747 is around 160 knots (184 mph), depending on the jet's wing flap configuration, the number of passengers aboard, and the weight of their luggage, fuel load, current weather conditions, and other factors. How Fast Do Airplanes Fly When Landing?

Can a 747 land without engines?

As for the loss of the engines, all airplanes can glide to a landing.

What is the slowest speed a 747 can fly?

What is the slowest speed a 747 can fly? It is around 140–160 kts, depends on the weather, fuel, and balance, cargo, flaps.

Can a 747 back up on its own?

no one ever does. Some aircraft can do a so-called 'powerback', but in most cases, airplanes either don't have this technical capability.

How long can a 747 stay airborne?

Flugzeuginfo.net notes that the range of a Boeing 747-200 is 12,700km - equating to a maximum of 14 hours of flight at cruising speed.

Can a 747 land with full fuel?

As long as you don't exceed the maximum landing weight of the aircraft, you should be fine.

How far can Cessna 172 glide?

How Far Can I Glide? How many miles you can glide per 1,000 feet of altitude is another very useful thing to know. A rule of thumb for Cessna 152s and 172s is 1.5 nautical miles per 1,000 feet of altitude above ground level.

How far can an A320 glide?

The glide ratio of a clean A320 is 17:1 which means it can travel 17 units of distance forwards for every 1 unit of distance downward at best glide speed. Using your figure of 11,000 meters away and multiplying by 17 results in a maximum range of 187km .

Which airliner has the best glide ratio?

According to its makers, the twin-jet wide-body Boeing 767 has a best glide ratio of about 20 to 1; that is, it can glide 20 feet forward for every foot of altitude it loses.
