Is there a weight limit for flying on an airplane?
There is no set weight limit for passengers on commercial flights in the U.S., but some airlines, most notably Southwest, require customers who cannot fit in one seat to book a second. Call the airline you wish to fly and ask about passenger size regulations.
Does your weight change on a plane?
You do weigh less when you’re higher up, but not by much (in Earth term). The force of gravity is F=G(m1xm2/r 2 ) where F is force, G is a constant, m1 and m2 are the masses of two objects and r is the distance between the centers of mass. The distance between the moon and the earth varies, but we’ll use 375,000 km.
Why is weight important in flight?
Weight and balance have a direct effect on the stability and performance of the aircraft. If a plane is too heavy, it may never get off the ground. If it’s out of balance, it may be uncontrollable when it does take flight. Maintaining proper weight and balance is an extremely important balancing act.
Does weight affect aircraft range?
Variations in aircraft weight do not affect the glide angle provided that the correct airspeed is flown. Since it is the lift over drag (L/D) ratio that determines the gliding range, weight will not affect it. The only effect weight has is to vary the time the aircraft will glide for.
Who is responsible for the correct weight and balance of every flight?
pilot
Who was the first man to break the sound barrier?
Charles Elwood “Chuck” Yeager
Who died trying to break the sound barrier?
Chuck Yeager
How did we break the sound barrier?
Yeager broke the sound barrier while flying over California’s Mojave Desert in 1947. His X-1 aircraft was lifted to 25,000 feet and then released through the bomb bay of a B-29, soaring to 40,000 feet and exceeding 662 mph, the sound barrier at that altitude
Who broke Mach 2?
A. Scott Crossfield
Why is it illegal to break the sound barrier?
Within the United States, it is illegal to break the sound barrier. When you pass Mach 1, the plane travels faster than the waves itself and that move across the so-called sound barrier produces a large sound, which is the sonic boom
Which is faster Mach 1 or Mach 2?
“Mach Number” was named after the Austrian physicist Ernst Mach. Mach 1 is the speed of sound, which is approximately 760 miles per hour at sea level. An airplane flying less than Mach 1 is traveling at subsonic speeds, faster than Mach 1 would be supersonic speeds and Mach 2 would be twice the speed of sound
Is there a sonic boom at Mach 2?
The wave speed for the sonic boom in air is the speed of sound. Whenever the plane is going faster than the speed of sound, it’s making a sonic boom that is always moving along with it. Nothing special happens at Mach 2. This is exactly like the wave of a boat.
Can Sonic Boom kill you?
Can a sonic boom kill you ? High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage. The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and might kills you
Can the pilot hear the sonic boom?
The short answer is – no, they don’t hear the sonic boom. Pilots and passengers cannot hear the sonic boom created by their own plane because they are at the head of the Mach cone. In simple words, they are moving so fast that the sonic boom doesn’t get a chance to catch up to them.
How far away can you hear sonic boom?
On most aircraft designs the characteristic distance is about 40,000 feet (12,000 m), meaning that below this altitude the sonic boom will be “softer”. However, the drag at this altitude or below makes supersonic travel particularly inefficient, which poses a serious problem.
Does a sonic boom only happen once?
The answer is: It doesn’t. Sonic boom first occurs when the plane crosses Mach 1 and the plane continues producing sonic boom as long as the speed stays above Mach 1. And the answer is: because the plane flew over you once. If the plane were to turn around and fly over you a second time you’d hear two sonic booms
Why do we not hear sonic booms anymore?
There’s no difference in sound inside the aircraft, since the whole shockwave system is moving along with the plane. If we aren’t hearing sonic booms regularly, that’s because a lot of effort and coordination go into making sure the booms don’t disturb civilian ears
Are sonic booms illegal?
Since 1973 civil supersonic transport has been banned over the United States, hindering private sector research and development. It’s time for the FAA to end its ban and create a supersonic noise standard to allow aviation innovation to flourish.
Can a human break the sound barrier?
The Austrian parachutist known as “Fearless Felix” reached 843.6 mph, according to the official numbers released Monday. That’s equivalent to Mach 1.25, or 1.25 times the speed of sound. Either way, he became the first human to break the sound barrier with only his body
At what speed does a sonic boom happen?
about 750 miles per hour
Is Thunder a sonic boom?
A sonic boom is created when an object travels faster than the speed of sound. The thunder that a storm makes is also a sonic boom caused by lightning forcing air to move faster than the speed of sound. The first plane to travel at the speed of sound was the Bell X-1 in 1947 and was piloted by Chuck Yeager.
Is Sonic faster than flash?
The Flash is faster than Sonic. Sonic the hedgehog runs at the speed of sound. While the Flash can run so fast he can jump through time. The Flash because Sonic can’t break the sound barrier and bend time.
Is lightning hotter than the sun?
Lightning is four times hotter than the sun. A return stroke of lightning, that is, a bolt shooting up from the ground to a cloud (after a stream of electricity came downward from a cloud) can peak at 50,000 degrees Fahrenheit (F). The surface of the sun is around 11,000 degrees F.
What is faster sound or light?
The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour.
Does light travel faster in water or diamond?
Light travels slower in diamond than it does in glass and slower in glass then it does in water. When light travels from air into a denser material such as water or glass it slows down and bends towards the normal.
What material slows down light the most?
Scientists slow down the speed of light travelling through air. Scientists have long known that the speed of light can be slowed slightly as it travels through materials such as water or glass
Can you film the speed of light?
Did you ever think you’d get to watch the speed of light filmed in a video in this lifetime? Science, yeah! Smartphones today can capture a video at 60 fps (frames per second). A camera at the California Institute can do the same but at 10 trillion fps or 000,000 frames per second
