How much fuel does a 747 burn on takeoff?
According to the Boeing website, the 747 burns approximately 12 litres per kilometre.
747 can carry as many as 568 people.
It can carry up to 238,840 litres of fuel..
Why do planes do not fly over the Pacific?
The primary reason airplanes don’t fly over the Pacific Ocean is because curved routes are shorter than straight routes. … Whether a commercial airline is flying from the United States to Asia or elsewhere, it will have the fastest and most fuel-efficient flight by performing a curved rout.
What is the slowest flying airplane?
MacCready Gossamer AlbatrossThe slowest powered plane ever flown (even if it was human powered) was the MacCready Gossamer Albatross. And it was very slow – topping out at 18mph.
Why do aircraft fly at 35000 feet?
The biggest reason for this altitude lies with fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak. Spending less on fuel is also great for airlines, for obvious reasons.
What is the fastest plane in history?
North American X-15Number 1: North American X-15 This aircraft has the current world record for the fastest manned aircraft. Its maximum speed was Mach 6.70 (about 7,200 km/h) which it attained on the 3rd of October 1967 thanks to its pilot William J.
Will Draco fly again?
Draco, on the other hand, will never fly again. Patey and his friends and family were in Nevada for the Reno National Championship Air Races.
How much does it cost to fuel a 747?
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 Slow Can a 747 fly?
Speeds vary according to performance, environmental conditions and weight but typically a fully loaded Boeing 747 on a normal long haul flight would take off from a typical length runway at around 160 knots which is 184 mph.
Do pilots sleep while flying?
Flight attendants and pilots get there own designated sleeping areas on long-haul flights built especially for them. While flight attendants are supposed to sleep on bunk beds in tiny crew rest areas, pilots take rest in separate sleeping compartments, where they can spend up to half of their time on a long flight.
Why do planes not fly straight across the Atlantic?
Ask the Captain: Why don’t planes fly in a ‘straight line?’ … Answer: It is shorter to fly the Great Circle route than a straight line due to the circumference of the earth being so much greater at the equator than near the poles. Q: Captain, I often follow trans-Atlantic flights between Europe and the USA.
Why do planes look still?
As a plane Spotter looks towards the airplane, it will look motionless at the right distance because the sunlight in the air will have a minor negative magnifying effect. It doesn’t last long and usually only occurs when the approach is observed with the airplane flying into the sun.
Does flying higher save fuel?
3 Answers. Flying higher means less drag because the air is thinner; therefore, you can fly faster at altitude and hence travel farther on less fuel. However, flying higher also means less oxygen available to burn your fuel, so available horsepower decreases with altitude.
Can you breathe at 35000 feet?
Whether you are flying aboard a small Cessna or a jumbo-sized Airbus A380, you can breathe freely inside the cabin without wearing a mask or respirator. Even at a cruising altitude of 35,000 feet, you shouldn’t have trouble breathing.
What happens if a plane flies too high?
When the plane gets too high, there is insufficient oxygen to fuel the engines. “The air is less dense at altitude, so the engine can suck in less and less air per second as it goes higher and at some point the engine can no longer develop sufficient power to climb.” …
How fast does a plane go when landing?
Big commercial airplanes generally fly in the 550-580 MPH range, but their landing and taking-off speeds are naturally going to be different. Most commercial planes take off at roughly 160 to 180 MPH, while landings take place at approximately 150 to 165 MPH.
Which is the most fuel efficient aircraft?
The Boeing 787-9 in particular was the most fuel-efficient aircraft on 2016 transpacific flights at 39 passenger kilometers per liter of fuel, or 60% better than the A380. There’s a reason airlines around the world are no longer buying very large aircraft like the 747 and A380.
Do planes fly slower now?
Despite advances in technology and increasingly better planes, flights are actually slower now than before. For example, back in the 1970s, a flight from New York to Houston, Texas, would take two hours and 37 minutes – but these days, it will take three hours and 50 minutes.
Why do planes fly so slow?
According to Business Insider, airlines can save millions of pounds every year by pilots flying a bit slower. That is because plane engines need to burn more fuel in order to go faster. … Fuel efficiency is also the reason that certain airlines are able to have cheaper flights than others.
How do airplanes save fuel consumption?
New technology can reduce engine fuel consumption, like higher pressure and bypass ratios, geared turbofans, Open rotors, Hybrid electric or fully electric propulsion; and airframe efficiency with retrofits, better materials and systems and advanced aerodynamics.
What is the most dangerous part of a flight?
Boeing research shows that takeoff and landing are statistically more dangerous than any other part of a flight. 49% of all fatal accidents happen during the final descent and landing phases of the average flight, while 14% of all fatal accidents happen during takeoff and initial climb.
Do planes fly over Everest?
According Debapriyo, most commercial airlines avoid flying directly over the Himalayas. This is because “the Himalayas have mountains higher than 20,000 feet, including Mt Everest standing at 29,035 feet. However, most commercial airplanes can fly at 30,000 feet.” … The Himalayan region has almost no flat surfaces.
