What layer do we live in?
TroposphereThe 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..
Can planes fly at 50000 feet?
Many business jets can travel even higher, at 50,000 feet, due to having large engines for the small size of the aircraft. The lighter weight enables these aircraft to climb higher more easily than larger jets with many passengers and materials.
Do Planes fly over Mount Everest?
Airplanes often avoid air paths that take them over Mt Everest or the Pacific Ocean. … 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.”
Can an airplane stay still in the air?
Can an Airplane stand still in mid-air? Technically, it is possible for an airplane to hover for a few moments, but only in the rarest of circumstances. If weight and lift cancel each other out at the same exact time that thrust and drag cancel each other out, the plane would hover until one of these variables changed.
At what height can you not breathe?
An elevation of about 20,000 feet above sea level is the maximum height at which sufficient oxygen exists in the air to sustain us. By comparison, the summit of Mount Everest (the Earth’s highest mountain) lies at 29,141 feet.
What height is the death zone?
8,000 mIn mountaineering, the death zone refers to altitudes above a certain point where the pressure of oxygen is insufficient to sustain human life for an extended time span. This point is generally tagged as 8,000 m (26,000 ft, less than 356 millibars of atmospheric pressure).
How many years can an airplane fly?
25 yearsThe average airplane can fly for around 25 years; some can fly for 30 years but never more than that.
Do planes fly in the troposphere?
The atmosphere is divided up into five main layers but commercial aircraft fly in the bottom two layers — the troposphere, which sits closest to the surface, and the stratosphere, which sits just above it. As you climb up into the troposphere, the air pressure, temperature and air density all decrease.
What is the hottest layer of the atmosphere?
thermosphereThe thermosphere is the hottest layer of the atmosphere.
What is the highest altitude you can fly without oxygen?
Federal Aviation Regulations say that without pressurization, pilots begin to need oxygen when they fly above 12,500 feet for more than 30 minutes, and passengers have to use it continuously above 15,000.
Can a plane fly at 60000 feet?
Some aircraft can fly higher Concorde has been the only significant exception amongst commercial aircraft. It could fly up to 60,000 feet due to the increased lift generated when flying at much higher speeds. At low altitudes, drag would prevent it from reaching its high speeds.
Can a plane accidentally fly into space?
As explained by NASA, airplanes are able to fly because of lift. … A main reason airplanes can’t fly in space is because there is no air. According to NASA, large commercial airplanes typically can’t fly higher than 7.5 miles. At this altitude, the air isn’t dense enough to support a large airplane.
Why do planes have to fly so high?
The reason aeroplanes fly so high is due to improved fuel efficiency. A jet engine operates more efficiently at higher altitude where the air is much thinner, allowing an aircraft to travel faster whilst at the same time, burning less fuel.
What is the highest altitude a 747 can fly?
45,100 ftThe 747 max altitude is 45,100 ft. The 757 max altitude is 42,000 ft. The 767 max altitude is 43,100 ft.
Can a bird fly over the ocean?
Many birds fly across the oceans and between continents in groups to follow food, habitat or weather conditions. … About 40 percent of the world’s bird species (at least 4,000 species) regularly migrate, some traveling across oceans, other traveling mainly overland.
At what altitude does it get hard to breathe?
It most often occurs at about 8,000 feet, or 2,438 meters, above sea level. Altitude sickness can affect people without COPD, but it may be more severe in people who do have COPD or some other type of lung condition. People who are physically exerting themselves are also more likely to experience altitude sickness.
What is the highest an airplane has flown?
Question: What is the highest altitude an airplane can fly? Answer: The highest commercial airliner altitude was 60,000 feet by Concorde. The highest military air-breathing engine airplane was the SR-71 — about 90,000 feet. The highest airliner flying today reaches 45,000 feet.
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.” …
Do airplanes fly above the ozone layer?
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.
How far can a pilot see at 35000 feet?
If you look up into space you are looking through about 62 miles of atmosphere, at 35,000 feet you will be looking through almost 230 miles of atmosphere to see the horizon.
Why do jets fly at 35000 feet?
The “sweet spot” of flying is regarded as between 35,000 and 42,000 feet – too high and the oxygen becomes too sparse to fuel the engines, too low and the air resistance is greater. This optimum height is linked to the usual weight of a commercial jet – that is, heavier planes fly lower, and lighter higher.
