What is the top speed of a Boeing 787?
The Boeing 787 has a cruising speed of approximately 560 mph (900 km/h) and a maximum speed of around 590 mph (950 km/h).
What is the average mass of a passenger jet?
Well, since the weight of planes varies so much, you cannot really put and "average" on the mass of an airframe. Some weigh 3000lbs, some weigh 1,000,000lbs. Also it changes everyday with temperature (true, believe it or not), passenger weight and other factors.
What is the coefficient of drag of a Boeing 747?
The coefficient of drag of a Boeing 747 can vary depending on its configuration and flight conditions, but it generally ranges from 0.022 to 0.025.
How to weight a Boeing 747-400?
To weigh a Boeing 747-400, the aircraft is typically placed on specialized scales at an airport or maintenance facility. The weight of the aircraft is then measured by the scales beneath each of its landing gear. The total weight is calculated by summing the weights measured at each point.
How much does the Boeing 747 weight in kg?
The weight of a Boeing 747 can vary depending on its model and configuration, but it typically ranges from 160,000 kg to 440,000 kg when empty.
What is the speed of a Boeing 747?
A Boeing 747 typically travels at a cruising speed of around 550-600 miles per hour (885-965 kilometers per hour). This speed can vary depending on factors such as altitude, weather conditions, and flight distance.
How long does it take to refuel an 777 airplane?
If we aks about the Boeing 777-200 LR, which have fuel tanks, that can carry 181,300L of fuel, and a avrage refuel pump for planes, which is able to pump about 2000 to 2400 liters per minute we can easily calculate, that it takes about 75.5416666667 to 90.65 minutes to fully refuel Boeing 777-200 from an empty to full tank.
A Boeing 747 typically cruises at a speed of around 550-600 miles per hour (880-960 kilometers per hour).
First, convert the speed from km/h to m/s: 300 km/h = 300 * (1000 m/3600 s) = 83.33 m/s. Then, calculate the acceleration using the formula: acceleration = change in velocity / time = (83.33 m/s - 0) / 25 s = 3.33 m/s^2.
What has the single biggest impact on fuel consumption?
Driving habits have the single biggest impact on fuel consumption. Aggressive driving, excessive speeding, and rapid acceleration can significantly increase fuel consumption. Maintaining a steady speed, avoiding sudden stops, and proper tire inflation can help improve fuel efficiency.
What is maximum speed while flying?
The maximum speed at which an aircraft can fly is determined by factors such as its design, engine power, and aerodynamics. Commercial jetliners typically fly around 550-600 mph, while military fighter jets can reach speeds exceeding Mach 2 (about 1,500 mph).
Does jet fuel burn hot enough to melt steel?
Construction grade steel burns at 2795 degrees Fahrenheit. Jet fuel does not burn this hot. Its maximum temperature is 1472 degrees Fahrenheit.
The maximum speed of a Boeing 747 is approximately 570 mph or 920 km/h. However, this speed can vary depending on factors such as altitude, weight, and weather conditions.
How do the different flaps on a plane work together to help it turn?
On mostly the larger aircraft, when you bank the plane either right or left the ailerons move like normal, like for a left turn the left one goes up pushing the left wing down and the right one goes down pushing the right wing up. but the aircraft is so heavy and big that it needs a little help, so along with the aileron they also move the outer flaps down a little on that wing to help push it up. they also use the spoilers on the left wing to help push that wing down. its all just enough to make the plane bank easier.
In order to make a proper turn in an airplane, the pilot first uses the ailerons to roll the aircraft in the desired direction. The ailerons will make the aircraft tend to yaw in the opposite direction due to the asymmetric drag they create (adverse yaw) and so the pilot will use the rudder to compensate.
Once the airplane is rolled to the desired bank angle, the pilot will then apply some nose-up pressure on the elevators to maintain altitude and press the rudder into the turn to maintain turn coordination. You can make a turn without rudder, but the aircraft will tend to "skid" (the tail of the aircraft doesnt exactly follow directly behind the nose, like sliding around a corner in the snow) which is considered very sloppy flying.
Once the turn is complete, the pilot will use the ailerons to level the aircraft, once again using rudder to compensate for adverse yaw, and providing the aircraft is trimmed for the desired attitude, release the upward pressure on the elevator.
Of course during the turn the pilot may have to make other adjustments to the aircrafts attitude using the control surfaces, such as maintaining the desired bank angle and correcting for wind gusts or air pockets.
(Additional comment to clarify good answer) Once the desired angle of bank is attained, the pilot will more or less centralise the yoke again, whilst maintaining the pressure on elevator and rudder, as he doesn't want the bank to increase any more. This is unlike driving a car when the steering wheel remains turned until the driver wants to exit the corner. A pilot will then apply opposite bank input to get the plane back straight and level again.
The questioner asks about "flaps". Since a "flap" is a specific flying control on an aeroplane, distinct from ailerons elevators, rudder and trim tabs, the question would be better put in asking about "control surfaces"
What is the maximum speed of a 747-400?
The 747-400, which is the most common variant in service, has a high-subsonic cruise speed of Mach 0.85-0.855 = up to 570 mph or 920 km/h
What is the volume of a Boeing 747?
The volume of a Boeing 747 varies based on its model and configuration. On average, the cabin volume of a Boeing 747 can range from approximately 280,000 to 300,000 cubic feet.
Jets use kerosene as fuel because it provides a high amount of energy for its weight, allowing for more efficient and longer flights compared to other fuels. Kerosene also has a lower risk of freezing at high altitudes and is more stable during storage, making it a reliable choice for aircraft operations.
What SUV has lumbar in the passenger seat?
The Toyota RAV4 is known to have lumbar support in the passenger seat in some of its trim levels, such as the Limited and Adventure models. It is important to check the specific trim level and features of each vehicle to confirm the presence of lumbar support in the passenger seat.
Most planes use a type of aviation fuel known as jet fuel. Jet fuel is a specialized type of fuel designed for use in jet engines, which power most commercial airplanes. It is a type of kerosene that is refined for its high energy content and stability at high altitudes.
Why is an aircraft categorized in heavier weight categories?
The regulations governing the various types of aircraft are based on weight categories. Different categories have different performance and equipment requirements. As a general rule, heavier categories of aircraft would be expected to have more stringent requirements with respect to performance and safety equipment, presumably because they would be more likely to be used in commercial aviation. Hope that helps.
How does an airplane take off?
During takeoff, an airplane's engines produce thrust, pushing the aircraft forward. As the speed increases, air flows over the wings, creating lift. When there is enough lift to overcome the aircraft's weight, it becomes airborne. The pilot then guides the plane into the sky.
How many gallons of fuel does a 1995 Honda Accord V6 hold?
A 1995 Honda Accord V6 typically holds around 17.1 gallons of fuel.
How much thrust is produced by a Boeing 747?
This information should be available on the Boeing website or other avaition-related websites.
For a quick answer, I will related my experiences from 1970's. Boeing certified the B747-200 to operate with General Electric CF6-50 engines. During take-off power, each GE engine could produce 56,000 lbs of thrust per enginer: or 224,000 lbs for a few minutes.
Now, the larger B747-400 a/c have more powerful engines. Currently each engine on a Boeing 747-400 can generate a maximum of about 63,300 lbs of thrust. Accordingly, since this aircraft has four engines it can produce total thrust of about 253,000 lbs.
Jet fuel is typically made from petroleum-based crude oil through a refining process that removes impurities. It is a type of aviation fuel designed for use in airplanes and usually consists of hydrocarbons, primarily refined from kerosene. The specific composition can vary depending on the grade of jet fuel and the additives used to improve performance and safety.
Only if the ballast is a multi tap ballast.
:Even if you could install a 120V ballast, or tap it to 120V with the existing one, Current may become an issue. To run the 400W light (sodium?) Now instead of the .833 amp range it's more like 3.33 amps. Supply wiring would have to be able to handle that. Those types of lights are often on long runs to building and grounds lights, parking lots, etc. Using 480 saves a lot on wiring costs.
