Could a plane fly in a vacuum?

Could a plane fly in a vacuum?       

Planes can and have flown into space for over 50 years – though not the kind you see at the airport. That’s because conventional planes need air for both propulsion and lift, and space is essentially a vacuum.

Why was the Aeroplane to stick in the air?          

The thrust is generated by the jet engines, and this helps the plane to propel forwards, whereas the lift force acts on the plane wings and allows it to move upwards, and also to maintain its altitude. For a plane to stay in the air, the lift force needs to overcome the force of gravity.

What stops a plane from flying?       

The brakes are used when the plane is on the ground to slow down the plane and get ready for stopping it. The top of the left rudder controls the left brake and the top of the right pedal controls the right brake.

Why can’t planes fly in the mesosphere? 

Aeroplanes and other modern aircraft can’t fly above 50 kilometres because the lower air density at these altitudes doesn’t allow for sufficient lift. On the flip side, the air in the mesosphere is too dense for the safe passage of satellites and could damage them, so it is off limits for them too.

What happens if a plane flies too high?      

If a passenger jet flies too high it reaches a point called ‘Coffin Corner’. This is the point at which the aircraft’s low speed stall and high-speed buffet meet and the plane can no longer maintain its altitude which forces it to descend.

What happens if you fly a plane into space?        

If an airplane flies in space, it won’t be able to suck in fresh air with which to supply its engines, resulting in loss of propulsion. The bottom line is that airplanes can’t fly in space because there is no air in space. Airplanes rely on air to produce both lift and propulsion.

Can airplanes stop in the air?         

No a plane doesn’t stop in midair, planes need to keep moving forward to remain in the air (unless they are VTOL capable). What it can do is simply turn around or go over/under the obstruction. VTOL means vertical takeoff and landing. It essentially means they can hover in place like a helicopter.

Can an airplane stay still in the air?           

To stay in the air and sustain its flight, an aircraft needs to be moving forward. … If the plane stopped flying forward, it could not produce lift, an thus could not stay up, unlike the helicopter which uses a propeller to stay airborne.

Do pilots prefer yoke or side stick?           

Side-sticks and centre-sticks are better for making rapid control inputs and dealing with high g-forces, hence their use in military, sport, and aerobatic aircraft. However, yokes are less sensitive (i.e., more precise) due to a larger range of motion and provide more visual feedback to the pilot.

How fast is a plane going at take off?          

A headwind will reduce the ground speed needed for takeoff, as there is a greater flow of air over the wings. Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph). Light aircraft, such as a Cessna 150, take off at around 100 km/h (54 kn; 62 mph).

How long can a plane stay in the air?       

Planes can now fly for 21 hours non-stop. 28-May-2019

What are the 4 forces of Flight?    

It flies because of four forces. These same four forces help an airplane fly. The four forces are lift, thrust, drag, and weight. As a Frisbee flies through the air, lift holds it up.

Do any planes fly in the mesosphere?          

The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet. Temperature decreases with height throughout the mesosphere. … Weather balloons and other aircraft cannot fly high enough to reach the mesosphere.

What layer do planes fly?   

Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere.

Can you survive if you will go to mesosphere for days?    

The air is still thin, so you wouldn’t be able to breathe up in the mesosphere. The meteors make it through the exosphere and thermosphere without much trouble because those layers don’t have much air. But when they hit the mesosphere, there are enough gases to cause friction and create heat.

Why do aircraft fly at 35000 feet? 

A balance between operating costs and fuel efficiency is achieved somewhere around 35,000 feet, which is why commercial airplanes usually fly at that altitude. Most commercial airplanes cruise at an altitude of nearly 35,000 feet—around 6.62 miles (10,600 meters) in the air!

Why do planes fly at 38000 feet?  

Those traveling in all other directions fly at even ones (32,000 feet, 38,000 feet, etc.). Planes traveling in the same direction fly 2,000 feet above or below other planes near them, to ensure they don’t collide or even get near each other.

How high is too high for a plane?  

Most commercial airplanes have a certified maximum altitude of about 40,000 to 45,000 feet. Regardless of its certified maximum altitude, if an airplane flies too high, it may fail in one or more ways. For starters, the engine may suffocate from a lack of oxygen.

Do planes fly over Everest?

Tim Morgan, a commercial pilot writing for Quora says aircraft can fly above 40,000 feet, and hence it is possible to fly over Mount Everest which stands at 29,031.69 feet. However, typical flight routes do not travel above Mount Everest as the mountains create unforgiving weather.

How cold is it at 35000 feet?          

The higher you get, the colder it gets, up until 40,000 feet. If the temperature at ground level was 20C, at 40,000 feet it would be -57C. At 35,000 feet the air temperature is about -54C.

Can a plane fly with one wing?      

No, an airplane cannot fly with only one wing. … With only one wing, the weight is shifted to one side of the plane. This makes it impossible to balance. There have been instances in history where pilots had to improvise when their planes lost one of their engines.

Do planes dump their waste in the air?    

Airlines are not allowed to dump their waste tanks in mid-flight, and pilots have no mechanism by which to do so; however, leaks sometimes do occur from a planes septic tank.

Why did planes have 2 wings?          

The main reason for having multiple wings in the initial years of the aviation was the lack of availability of materials with sufficient strength. The main advantage of the biplane is that the wings could be shorter for a given lift.

What is the slowest speed a plane can fly?             

Aeroplanes, or airplanes if you’re American, need to maintain a certain speed to allow flight. Technically this is the so-called ‘stall speed’, where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph).

Why do planes not freeze in the air?           

The absence of water in colder temperatures means there is nothing to form ice from. … These droplets do not have a freezing nuclei and thus will stay liquid even at temperatures below zero. However, when an airplane comes in contact with it, the airplane acts as the freezing nuclei, freezing the droplets immediately.

Do airplanes have a speed limit?      

Although there is not a specific speed limit for commercial planes above 10,000 feet, pilots have to abide by the aircraft manufacturer’s maximum safe speed for the aircraft to fly. … The speed limit for these areas is 200 knots (230mph).

Can helicopters stop in mid air?       

A helicopter that is flying forward can stop in mid-air and begin hovering very quickly. We’ll cover this signature maneuver next.

Why do pilots move the yoke so much?   

Constant yoke movements because constant correction is required. It depends on how still or rough the air is… in turbulence you will see much more yoke movement by the pilot to keep the aircraft on the desired trajectory. Smooth air requires much less.

Who is bigger Boeing or Airbus?      

The competition between Airbus and Boeing has been characterised as a duopoly in the large jet airliner market since the 1990s. In 2019, Airbus displaced Boeing as the largest aerospace company by revenue due to the Boeing 737 MAX groundings, with revenues of US$78.9 billion and US$76 billion respectively.

Can a Boeing pilot fly Airbus?        

This means that, for example, while the 737 and 747 are both Boeing aircraft, pilots cannot simply jump between the two without obtaining the necessary type rating. In conclusion, at face value, Airbus and Boeing pilots cannot legally fly each other’s aircraft.

Are pilots scared of turbulence?      

In short, pilots are not worried about turbulence – avoiding it is for convenience and comfort rather than safety. … Turbulence is graded on a scale of severity: light, moderate, severe and extreme. Extreme is rare but still not dangerous, although the plane will subsequently be examined by maintenance staff.

What is the fastest jet in the world?         

Lockheed SR-71 Blackbird  The Lockheed SR-71 Blackbird is the fastest jet aircraft in the world, reaching speeds of Mach 3.3–that’s more than 3,500 kph (2,100 mph) and almost four times as fast as the average cruising speed of a commercial airliner.

Do pilots turn off engines? 

Pilots have come out and said that while we’re in the air eating our boxed dinner or packaged snack, they turn the engines off. … It also means that if there is an emergency situation and the engines do fail, flight crews have time to solve the issue.

What happens if both engines fail on a plane over the Atlantic?         

If all of an airplane’s engines fail simultaneously, the pilot will perform an emergency landing. As the airplane descends and decelerates, the pilot will begin to search for a safe area to perform an emergency landing. Ideally, the pilot will land on a nearby landing.

How long can a plane fly without engine?

A passenger jet could glide for up to about 60 miles if it suffers a total engine failure at its cruising altitude. Here’s an example. A typical commercial aircraft has a lift to drag ratio of around 10:1. This means that for every 10 miles it travels forward it loses 1 mile in altitude.

Why can humans not fly?      

Humans are not physically designed to fly. We cannot create enough lift to overcome the force of gravity (or our weight). … Their light frame and hollow bones make it easier to counteract gravity. Air sacs inside their bodies make birds lighter, which enables smoother motion through air.

How do planes fly in Bernoulli’s principle?           

Since high pressure always moves toward low pressure, the air below the wing pushes upward toward the air above the wing. The wing, in the middle, is then “lifted” by the force of the air perpendicular to the wing. The faster an airplane moves, the more lift there is.

Can an airplane fly without a propeller?      

Plane generates thrust from ‘ionic wind’ using powerful electric field. A nearly silent, drone-sized aircraft has shown it can fly, thanks to a scientist who was inspired by watching Star Trek as a child. With neither propellers nor jets, the airplane gets its thrust by applying a strong electric field to the air.

What is the hottest layer?  

The thermosphere is often considered the “”hot layer”” because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. Temperatures can reach as high as 2000 K or 1727 ºC in this layer (Wallace and Hobbs 24).

How thick is the mesosphere inside the Earth?   

Roughly 2,200km Mesosphere –The mesosphere is another rigid layer in the earth and it is roughly 2,200km in thickness.

What is the temperature range of the mesosphere?      

The mesosphere starts at 31 miles (50 km) and extends to 53 miles (85 km) high. The top of the mesosphere, called the mesopause, is the coldest part of Earth’s atmosphere, with temperatures averaging about minus 130 degrees F (minus 90 C).

What airline has never had a crash?         

Qantas holds the distinction of being the only airline that Dustin Hoffman’s character in the 1988 movie “Rain Man” would fly because it had “never crashed.” The airline suffered fatal crashes of small aircraft prior to 1951 but has had no fatalities in the 70 years since.

What layer do we live in?   

The Troposphere: Beginning at the surface of Earth, the troposphere extends to around seven miles up. This is the layer we live in and contains most of what we consider to be “the atmosphere”, including the air we breathe and nearly all of the weather and clouds we see. 22-Feb-2016

Why can’t planes fly in the mesosphere? 

Aeroplanes and other modern aircraft can’t fly above 50 kilometres because the lower air density at these altitudes doesn’t allow for sufficient lift. On the flip side, the air in the mesosphere is too dense for the safe passage of satellites and could damage them, so it is off limits for them too.

What is the coldest layer of the atmosphere?        

 Located between about 50 and 80 kilometers (31 and 50 miles) above Earth’s surface, the mesosphere gets progressively colder with altitude. In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit).

How high is the thermosphere in KM?     

Between about 53 miles (85 km) and 375 miles (600 km) lies the thermosphere. This layer is known as the upper atmosphere. While still extremely thin, the gases of the thermosphere become increasingly denser as one descends toward the earth.

How does mesosphere protect the Earth?          

The mesosphere burns up most meteors and asteroids before they are able to reach the earth’s surface. The mesosphere is the coldest atmospheric layer surrounding the earth. It becomes cold enough to freeze water vapour in its atmosphere into ice clouds. These layers protect our planet by absorbing harmful radiation.
