How fast does a 747 go when landing?
How fast does a 747 go when landing? What speed does a Boeing 747 land at? A 747 'Jumbo Jet' would typically land at a speed of about 145kts-150kts (166mph-172mph), depending on the landing flap setting selected.
What is the takeoff distance of a 747?
Takeoff distance 10,450. Landing distance 6,920. The Boeing 747 was designed to carry large numbers of passengers at low cost. The basic passenger design, designated 747-200B, is capable of carrying up to 500 passengers in a 10-abreast seating arrangement.
How many hours can a 747 fly?
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!
Why does 747 fly so fast?
Its wings have a high sweep angle of 37.5° for a fast, efficient cruise speed of Mach 0.84 to 0.88, depending on the variant. The sweep also reduces the wingspan, allowing the 747 to use existing hangars.
Can a 747 break the speed of sound?
Aircraft are put through extreme testing during their certification, but such limits are never intended to be actually faced. The 747-100, for instance, was tested up to Mach 0.99, almost breaking the sound barrier. Other 747s, such as Air Force One, have approached the sound barrier but never crossed it.
What speed does a 747 cruise at?
On average, the typical cruising speed of a large commercial aircraft, like a Boeing 747, is somewhere between 475 and 500 knots (roughly 575 mph). So what is the cruising speed of a 747? Depending on passenger load, the average cruise speed of a 747 is 490 nautical miles or Mach 0.85.
Why are 747 being phased out?
Hard to maintain Ultimately, the age of the type has reduced its efficiency across the board. Munoz said the following, as reported by Business Insider. You've got other jumbo jets out there that are being built and that a couple of people are flying. For us, we had dwindled down our fleet of 747s.
What is the highest altitude a 747 can fly?
Different airplanes have different maximum altitudes, depending on their construction. For example, the Airbus A320 has a maximum altitude of 39,000 feet (11,900m) and the Boeing 747 45,000 feet (13,700m).
Why do planes fly at 30000 feet?
The reason planes cruise at high altitudes is that they burn less fuel and can fly faster, as the air is less dense. At 30,000 feet and higher, it is also possible for aircraft to avoid weather systems, making it more comfortable onboard.
What seats on a plane are the safest?
The middle seats are safer than the window or aisle seats, as you might expect, because of the buffer provided by having people on either side, professor Drury said to the Conversation. He noted that sitting next to an exit row can ensure a quick exit if there is an emergency, except in case if there is a fire.
What is the fastest a 747 has ever flown?
Aided by a more powerful jet stream than usual, this rapid journey saw the 747 reach a top speed of 825 mph. Photo: Markus Mainka I Shutterstock. Popular Mechanics reports that the reason for it being so powerful on this occasion was a 'bomb cyclone' near Greenland.
Why do planes slow down after takeoff?
Question: Right after takeoff, it often seems that the pilot slows down and the plane drops somewhat. Why is that? I have noticed that it is pretty consistent. Answer: The sensation of slowing down is really one of slowing the rate of acceleration; this is due to reducing the thrust after takeoff to the climb setting.
How fast does a 747 descend?
35 x 3=105. This means you should begin your descent 105 nautical miles from your destination, maintaining a speed of 250 KIAS (about 45 percent N1) and a descent rate of 1,500 to 2,000 feet per minute, with thrust set at idle.
What is the speed of a plane landing?
Landing. While landing, speed is largely affected by the aircrafts current weight, commercial airplanes typically land between 130 and 160 mph (112 to 156 knots).
Will a plane land in 40 mph winds?
With this in mind, horizontal winds (also known as “crosswinds”) in excess of 30-35 kts (about 34-40 mph) are generally prohibitive of take-off and landing. As far as how this happens, it depends on where you are in flight.
Why do planes take off so steeply?
The idea is to get as much altitude as possible, as close to the airport as possible. So you have a relatively steep initial climb, followed by a reduction of climb angle to cruise climb and a power reduction.
Why do planes speed up before landing?
As the plane descends into ground effect, it may actually accelerate if the engines are producing enough thrust, since in ground effect the plane requires much less power to keep flying. Power from the engines will translate into speed, if not height.
