How fast does a 747 have to be going to stay in the air?

Registered. Take off speed for a 747 is between 178-184 mph, that is the minimum speed the aircraft needs to obtain to become airbourne.

How fast do planes have to go to stay in the air?

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 does a 747 go when landing?

Landing Speed By Aircraft Type

Commercial Airliner: A commercial airliner, like a Boeing 747, lands at an average speed of approximately 150 knots (172mph).

How fast does a commercial airliner have to be going to take off?

Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph). Light aircraft, such as a Cessna 150, take off at around 100 km/h (54 kn; 62 mph). Ultralights have even lower takeoff speeds.

Why do planes speed up before landing?

The aircraft flares just before touching down. It descends with a constant velocity, and just before touching down pulls the nose up to reduce the descent. This results in a higher angle of attack, more lift, and a vertical deceleration of the airplane.

How high can a 747 fly?

Boeing 747

Lufthansa previously bragged that its 747-400 could reach the highest altitude in its fleet, reaching a max altitude of 44,947 ft (13,610 m). Meanwhile, the modern 747-8, which is well deployed by the carrier, has a service ceiling of 43,100 ft (13,137 m).

Can a Boeing 747 fly on one engine?

While it's very clear that a 747 is unable to properly fly with the failure of three engines, we can see that a single functioning engine would at least extend the aircraft's distance and prolong its time in the air.

Can a 747 take off with 3 engines?

The 747 is certified to fly on just three engines, and there was no indication of any damage to the aircraft's other engines. Safety experts and aviation regulators still questioned the decision to operate such a long flight with one engine out.

How much does a 747 engine cost?

Cost of Parts

An airplane's parts and components can be very expensive, especially when it comes to the engines. The Boeing 747-8 uses 4 General Electric GEnx engines, which cost $13 million each, meaning that replacing all four of a Boeing 747-8's engines costs $52 million.

What is the slowest speed a 737 can fly?

The stalling speed in a landing configuration for a 737 is probably around 108 knots. The stalling speed in a clean configuration is around 128 knots. The landing speed is about 140 knots.

What is the fastest plane speed?

The NASA/USAF X-15 is the fastest fighter jet ever produced. It reached record top speed of Mach 6.72 or 4,520 mph, which is more than five times the speed of sound.

What is the slowest a fighter jet can fly?

It depends on weight and altitude, so there is no one answer, but it goes down to 100 knots and below. The most popular GA aircraft, the Cessna 172, has an official cruise speed of 122 knots. This is within the operating limits of most jet fighters, except when overloaded or at altitude above that of GA aircraft.

How much does it cost to fill a 747 with fuel?

Seats to fill

A 747 can seat 380 to 560 people, depending on how an airline sets it up. A full one is a moneymaker. But an airline that can't fill all the seats has to spread the cost of 63,000 gallons of jet fuel — roughly $200,000 — among fewer passengers. The jets also are too big for most markets.

How much does a scrap 747 cost?

A 747 can fetch up to $55,000 for its scrap alone.

How much fuel does a 747 carry?

Let's start with a look at the most famous of jets, the Boeing 747. The Boeing website states that this model, with a gas tank capacity of 63,500 gallons, may burn five gallons of jet fuel per mile of flight. A 4,000-mile flight, then, requires 20,000 gallons of fuel.

Could a 747 land on an aircraft carrier?

Large commercial aircraft like a Boeing 747 or an Airbus A-380 simply cannot fit on the deck without the wings clipping the island or other deck antennas, etc, not to mention requiring landing rolls of over 3000 ft even in the most extreme short field attempts.

Can a plane fly with one wing?

The F-15 has endured because its design was years ahead of its time, and a great data point behind that fact is the time Israeli pilot Zivi Nedivi landed his jet with only one wing. Nedivi had one of his wings sheared off in a midair collision with an A-4 Skyhawk during a training event.

Can a 747 land without engines?

The higher you get, the less dense air is, which reduces friction and allows reaching higher speed. An engine failure means that the plane is going to have less power and will be forced to fly at a lower altitude. That is enough to warrant an emergency landing. The same can be said about the Boeing 747.

How far can a 747 glide without power?

For example, with a glide ratio of 15:1, a Boeing 747-200 can glide for 150 kilometres (93 mi) from a cruising altitude of 10,000 metres (33,000 ft).

Can you fly a 747 upside down?

The scene, a Hollywood masterpiece of special effects, has people asking can an airliner 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.

Can a 747 back up?

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.

What is the highest a plane has ever flown?

It doesn't seem fair. On July 17, 1962, American test pilot Robert White took the X-15 to an altitude of 314,688 feet. But it's Russian pilot Alexandr Fedotov who holds the world altitude record, set on August 31, 1977, when his MiG E-266M reached a mere 123,523 feet.

What happens if a plane flies too high?

If a passenger jet flies too high, it reaches a point called 'Coffin Corner'. This is the point at which the aircraft's low speed stall and high-speed buffet meet and the plane can no longer maintain its altitude which forces it to descend.

Can airplanes fly over Mount Everest?

Tim Morgan, a commercial pilot writing for Quora says aircraft can fly above 40,000 feet, and hence it is possible to fly over Mount Everest which stands at 29,031.69 feet. However, typical flight routes do not travel above Mount Everest as the mountains create unforgiving weather.

How much do 747 pilots make?
