It backs up by either a pushback tug which's the normal way and also it can use the thrust reverser for a limited time and usually is not recommended by airliners.

Mach 0.80 (530 mph or 458 knots) at 35,000 ft.

B787-3:170,000 kg

B787-8: 228,000 kg

B787-9: 247,000 kg

The 747 normally uses fuel called Jet A. The are other variants, Jet A1, JP4 etc. All are forms of kerosene.

The maximum altitude for a 747 is 45,100 feet.

you don't fly, you glide and hope you get lucky to land at the nearest airport or land in a nearby, wide river because the 747-8 has a wingspan of 68.5 meters in length. If you are talking about another model of 747, the wingspans are roughly the same size.

no it cannot take off if it is going slow

A 747-400 has 171 miles (274 km) of wiring.

After 5 minutes it's assumed that it's still in climb and on its standard departure route therefore the maximum speed will be 250 knots as it's below 10,000 feet. Only act can provide permission to exceed this. Note, authors after take off are governed by specific speeds and sound regulations , each airport will have it's departures speeds set

380 knots ave

The biggest airplane maker in the world is either Boeing or Airbus, they constantly 'flip flop' control around

Airplanes refuel in the ground. Trucks carrying airplane fuel come and refuel the aircraft.Some jet aircraft have the capability of refuelling in the air.

It made it's first test flight on Feb. 2, 1969.

there are many types of 747's

When aircraft generate lift to fly, they leave an area of disturbed air behind them known as wake turbulence which can badly affect the control of following aircraft. This is especially dangerous during takeoff and landing, where the loss of control close to the ground can easily cause a crash.

The heavier the aircraft, the stronger the wake turbulence. For this reason, the interval is increased in most instances for aircraft following or landing behind a heavy aircraft.

The International Civil Aviation Organization (ICAO) uses three standard size classifications for planes based on their maximum takeoff weight;

Heavy : 136,000+ Kg

Medium : 7,000 - 125,599 Kg

Light : 7,000 kg or less.

In the United States, aircraft capable of a maximum takeoff weight of 300,000 pounds or more are classified as "heavy", even if the aircraft happens to be operating below that weight. Aircraft with a maximum takeoff weight over 14,500 pounds and less than 300,000 pounds are classified as "large". Aircraft with a maximum takeoff weight of 14,500 pounds or less are classified as "small".

There is a new category called 'super' which has been introduced just for the Airbus A380 and Boeing 747-800.

The separation between two "Supers" following each other is 4 nautical miles (nm). A large aircraft behind a super needs 10 nm separation.

The distance between two "heavy" craft is also 4 nm, a "large" or "medium" following a "heavy" needs 5 nm.

To make other craft aware of the status of heavies and supers, air traffic controllers controlling aircraft in the vicinity of airports use the convention of including the "heavy" or "super" weight classification in the aircraft call sign - "United 29 Heavy", for example. Controllers also issue a cautionary advisory to aircraft landing behing a heavy or super - "...following a heavy Boeing seven sixty seven, caution wake turbulence".

The greatest number of passengers ever carried by a commercial airliner is 1,088, by an El Al Boeing 747 during Operation Solomon, which involved the evacuation of Ethiopian Jews from Addis Ababa, Ethiopia, and started on 24 May 1991. This figure included two babies born on the flight.

Going by this statement the 225 has a third greater volume which gives the answer of approx 1450 passengers.

Generally speaking, yes. Though it depends on many factors.

i think only two people can travel on a biplane because that is why it is called a biplane...

Passenger versions of the 767 can carry between 181 and 375 passengers, and have a range of 5,200 to 6,590 nautical miles (9,400 to 12,200 km) depending on variant and seating configuration.

The British/French built Concorde was the only scheduled supersonic transport (SST) to carry passengers across the Atlantic.

A 777-200 takes 440 passengers while a 777-300 takes 550 passengers.
