Can planes fly above stratosphere?
Airplanes do not fly any higher than the stratosphere. In regards to commercial flight, when Concorde was still in operation, its maximum cruising altitude was 60,000 feet. For military aircraft, in 1976, the Lockheed SR-71 set the record for the highest altitude achieved in horizontal flight at 85,069 feet.
Do planes enter the stratosphere?
The temperatures in the stratosphere are inverse to those in the troposphere, meaning they rise with altitude. The reason airplanes fly through the stratosphere is that doing so is the most efficient way for fuel consumption.
What layer of the atmosphere do planes fly in?
The layer in which aircraft fly is the troposphere, the layer closest to the Earth, although within this layer, each type of aircraft uses a different altitude depending on its needs.
Why do jet planes fly in stratosphere?
The stratosphere is free from water vapour and dust particles. Absence of clouds and any other factors which may contribute to turbulence in the air makes it a perfect layer for flying jet aircrafts.
What is the highest altitude a plane 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. The highest business jet flying today reaches 51,000 feet.
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.
Can you breathe in the stratosphere?
2.1 The Density and Temperature of Air. The stratosphere is not a good place to be. First, the ozone in the stratosphere, which protects us from biologically destructive solar ultraviolet light, exists at such high levels that the air itself is toxic. Second, even this toxic air is much too thin for normal breathing.
Can planes fly in the thermosphere?
Remember also the plane can't fly in the thermosphere. Another important point in this problem is that not only plane weather balloons as well as satellites are also not able to fly in this layer of atmosphere called Mesosphere.
Do planes fly in the troposphere or the stratosphere?
You'll probably discover that it flies somewhere in the troposphere, which is important for two reasons: the air is thin enough to minimize drag, yet it's also thick enough to produce an adequate amount of lift. For these reasons, commercial jets almost always fly in the troposphere.
Why do planes do not fly over the Pacific?
Most commercial airlines, that operate between East Asia and the Americas, do not fly over the Pacific Ocean because of cost and safety concerns, including turbulent weather, which can be dangerous to fly over.
At what layer do most airplanes fly at the top of?
Stratosphere Complete Step by Step Answer: Stratosphere is the layer of the atmosphere where planes usually fly. It usually extends up to 50 km above the ground. Most of the jet aircraft fly in the lower layer of the stratosphere, to avoid any turbulence, although thunderstorms do penetrate the stratosphere.
Do planes fly in the troposphere?
Although there are exceptions, most commercial jets fly at around 28,000 to 35,000 feet. Being that Earth's troposphere is between 23,000 and 65,000 feet — depending on the season and latitude, at least — this means that commercial jets are almost always within the troposphere.
Can a plane fly over Mount 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.
Why do planes not fly over the Pacific?
Flying over the Pacific Ocean is avoided by most airlines for most flights because it usually doesn't make sense to fly over it when shorter and safer routes exist. The Pacific Ocean is also more remote and less safe than the Indian and Atlantic Oceans to fly over, resulting in a higher chance of a plane crashing.
Can you break a plane window?
Chartered aeronautical engineer Guy Gratton said plane windows are thick and strong but "like anything else, they're capable of being broken". He told the Press Association: "If you lose a window, then you've punched a hole in the pressure vessel. "The air inside will try to escape.
At what height is there no oxygen?
26,000 ft It refers to altitudes above a certain point where the amount 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).
At what altitude can humans survive?
Between 62,000 and 63,500 feet (18,900 and 19,350 meters) blood begins to boil at body temperature. This altitude, referred to as the Armstrong limit, is generally considered to be the absolute limit compatible with life. At this point, humans cannot survive without pressurization measures.
Do any planes fly in the mesosphere?
In short we can say it is very cold,the air in the mesosphere is very thin and it is the highest layer and very far away from our planet hence it is very difficult to survive in this layer. We conclude that planes cannot fly in the mesosphere. Note: Remember also the plane can't fly in the thermosphere.
Can planes fly in troposphere?
You'll probably discover that it flies somewhere in the troposphere, which is important for two reasons: the air is thin enough to minimize drag, yet it's also thick enough to produce an adequate amount of lift. For these reasons, commercial jets almost always fly in the troposphere.
What layer does a helicopter fly?
Helicopters and light aircraft typically fly in the troposphere.
Why do flights to Japan go over Alaska?
Commercial airlines typically fly a Northern curved route that goes over Canada and Alaska. Therefore, they spend less time over the Pacific Ocean, allowing for emergency landings if needed.
Why don’t we fly from Alaska to Russia?
The Alaska ADIZ is a buffer zone of thousands of square miles that isn't sovereign airspace—Russian planes can legally fly there—but entering the zone means a plane could conceivably enter U.S. airspace in a relatively short amount of time.
Why planes do not fly over Pacific Ocean?
Weather Patterns. Most flights are planned to minimize the time spent over bodies of water, since storms are more likely to occur over water than land. The weather over the Pacific Ocean is often turbulent, and there are many thunderstorms in parts of the Pacific, so it's not a safe environment to fly a plane.
Why do planes not fly over Antarctica?
Antarctica has no flight paths due to weather conditions and no infrastructure to assist with landing anywhere on the continent.
Why are lights turned off during landing?
Airlines are today required to turn off plane lights during takeoff and landing. The reason this is done is because of the time it takes for our eyes to adjust to the dark. It can take our eyes between 10 to 30 minutes to adjust to darkness.
Can plane fly over Mount 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.
Do Pilots breathe pure oxygen?
Today's fighter pilots therefore operate in cabins pressurized according to a pressurization schedule,15 they breathe up to 100% oxygen,15 and they wear and use pressure breathing equipment.
Can you breathe above the clouds?
At 70,000 feet, as indicated by radar, that's some 40,000 feet higher than the border of the troposphere (where 99.9% of, "weather" happens). There's certainly no oxygen up there to sustain life.
How thin is the air at the top of Mount Everest?
When you go to a high elevation there is less air pressure. The lower air pressure makes air less dense (thinner) and so there is less oxygen in the air you breathe. At the top of Mount Everest there is only ⅓ of the oxygen available as there is at sea level.
What is Everest death zone?
It's called the “death zone.” To prepare, climbers must give their bodies time to get used to higher altitude. That's why they normally spend several weeks climbing Mount Everest. They stop to rest every few thousand feet. When they reach 26,247 feet (8,000 meters), they've entered the death zone.
