The 747 goes from its approximate takeoff speed of 200 mph (89.4 meters per second) to 0 mph in 27 seconds.
At what speed does a 747 leave the ground?
184 mph
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.
How fast does a 747 go mph?
659.85 mph
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.
How fast is a commercial jet going when it takes off?
Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph).
How far can a 747 fly without refueling?
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!
How long of a runway does a 747 need to take off?
The Princess Juliana runway is only 7,546 ft, but according to Wikipedia, the 747 needs more than 10,000 ft of runway for take-off.
Can a 747 land itself?
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.
Can a 747 land on water?
4 November 1993: China Airlines Flight 605, a Boeing 747-409, ended up in water after it overran runway 13 at Kai Tak International Airport on landing during a typhoon with wind gusting to gale force. All of the 396 occupants donned life-vests, boarded the eight slide/rafts and no fatalities resulted.
What’s the slowest a 747 can fly?
It is around 140–160 kts, depends on the weather, fuel, and balance, cargo, flaps. The stall speed is published as 138 Kts/160 mph, so roughly 20 above that to maintain level flight.
What plane takes off the fastest?
The honor goes to the Concorde, which could cruise at Mach 2.04 or 1,354 miles per hour.
How fast is the air coming out of a jet engine?
1,300 mph
A typical speed for air molecules exiting the engine is 1,300 mph (2,092 kph). The bypass air generated by the fan – This bypass air moves at a slower speed than the exhaust from the turbine, but the fan moves a lot of air.
Do planes use full throttle on takeoff?
Pilots typically push it to full or almost full throttle the second they begin to accelerate for take off. The slow increase you feel is actually not a slow increase in thrust (the force applied to move the plane forward), but the rate at which the heavy plane full of people is accelerating (increasing in speed).
How much does it cost to fill a 747 fuel tank?
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.
How much does it cost in fuel to fly a 747?
The cost to fuel a plane largely depends on local fuel prices and the supply of crude oil. Going by averages, it would cost between $170,000-$200,000 to fuel a Boeing 747-8. The Airbus A380-800 costs more at $230,000-$260,000 to fuel.
How many gallons does a 747 carry a fuel?
A Boeing 747 can hold approximately 48,400 – 57,285 gallons of jet fuel depending on the model of aircraft (model series 100 – 400). This is 183,214 to 216,847 liters of fuel or about 180 to 213 tonnes.
How long can you legally sit on a runway?
For flights landing at U.S. airports, airlines are required to provide passengers with an opportunity to safely get off of the airplane before 3 hours for domestic flights and 4 hours for international flights.
How long do 747 engines last?
On average, an aircraft is operable for about 30 years before it has to be retired. A Boeing 747 can endure about 35,000 pressurization cycles and flights—roughly 135,000 to 165,000 flight hours—before metal fatigue sets in.
Why do planes wait 3 minutes on the runway?
They are probably just waiting for the aircraft that took off before them to get far enough away. You don’t want to fly too close behind another aircraft because of the turbulence in their wake. There could also be an aircraft taking off or landing on another runway that they have to wait for.
Can a 747 land with full fuel?
Larger planes like the Boeing 747, on the other hand, have fuel jettison systems. If the aircraft tried to land without dumping the fuel first, it is considered an overweight landing attempt and could place immense stress on the airframe.
Can a 747 fly without a pilot?
(A handful of older Boeing 747s, which require flight engineers, continue to fly cargo routes.) Nowadays, Federal Aviation Administration regulations make a two-person crew standard. But the FAA also requires that in an emergency, airliners must be capable of being flown by a single pilot.
Do pilots sleep while flying?
The simple answer is yes, pilots do, and are allowed to sleep during flight but there are strict rules controlling this practice. Pilots would only normally sleep on long haul flights, although sleep on short haul flights is permitted to avoid the effects of fatigue.
