Do 747s have an elevator?

Service elevators in the cabin

The Airbus A380 has two elevators installed to transport galley containers between the upper and lower decks, as does the Boeing 747.

Does aircraft have elevator?

Description. An elevator is a primary flight control surface that controls movement about the lateral axis of an aircraft. This movement is referred to as "pitch". Most aircraft have two elevators, one of which is mounted on the trailing edge of each half of the horizontal stabilizer.

Does a 747 have 2 floors?

One of the key features of the Boeing 747 and the Airbus A380 is their double-deck design. On two levels, airlines can provide every comfort for premium passengers, or can use the space to pack in over 600 passengers.

How much lift does a Boeing 747 have?

The wings of a Boeing 747 have a surface area of about 510 square meters (5,500 square feet) and can produce as much as 390 tons (850,000 pounds) of lift.

Why do 747s have a hump?

Boeing decided to raise the cockpit above the nose cone, and — in order to maximize the planes aerodynamic efficiency — the hump was born. Later versions of the 747 would extend the hump further back on the plane, creating more room for premium cabin seats in the upper deck.

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 long does it take to fuel a 747?

With one fuel truck, a Boeing 737 can be fuelled from empty in around 23 minutes. A Boeing 747 using two fuel trucks with dual nozzles in around 52 minutes.

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.

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).

Has Boeing 747 ever crashed?

On July 28, 2011, Asiana Airlines Flight 991, a 747-400F, caught fire and crashed in the sea near Jeju island, killing both crew members. On April 29, 2013, National Airlines Flight 102, 747-400BCF, stalled and crashed shortly after taking off from Bagram Airfield in Bagram, killing all seven crew members.

Is it impossible to open a plane door in flight?

While the news never fails to report these events, it seldom mentions the most important fact: you cannot –- repeat, cannot — open the doors or emergency hatches of an airplane in flight. You can't open them for the simple reason that cabin pressure won't allow it.

Is Boeing 777 bigger than 747?

The 777X is a longer aircraft - just

According to Boeing's data, the 777-9 has a total length of 251 feet 9 inches (76.72 meters). The 747-8 is just a bit smaller at 250 feet 2 inches (76.3 meters). The 777-9 is the longest commercial aircraft ever built.

What happens if a plane depressurized?

When a cabin depressurizes, the percentage of oxygen in the air stays about the same, but the molecules get further and further apart, Padfield explained. “Imagine a balloon at sea level, then take it up to 10,000 feet. The balloon gets bigger because there is less pressure pushing in against it,” he said.

Can a plane fly without elevator?

As the two airline crews above demonstrated, it's sometimes possible to fly an airplane with little or no aerodynamic control. In fact, a fairly adept pilot can sometimes take off and land some airplanes without using the elevators or ailerons at all.

How do airplanes stay in the air without falling?

A plane's engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky.

Has a 747 ever broken 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.

How fast does a Boeing 747 go to take off?

The 747 goes from its approximate takeoff speed of 200 mph (89.4 meters per second) to 0 mph in 27 seconds.

How fast does a 747 fly in mph?

Boeing 747-8

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 0.86. That's equivalent to 659.85 mph.

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 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.

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.

How much does it cost to fly a 747 per hour?

More engines lead to higher prices. The average airborne operating cost of a Boeing 747-400 is between $24,000 and $27,000 per hour, around $39.08 to $43.97 per mile, using approximately $15,374 in fuel per hour.

Why do planes not freeze in the air?

At an altitude of 35,000 feet, however, the clouds are made of ice crystals so no supercooled droplets exist thus, airplanes do not face icing issues.

How far can a 747 fly without refueling?

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). This means it can fly non stop for almost 16 hours!
