Since 36,000 feet is a further 7000 feet higher than the peak of Mount Everest, the air up there is pretty thin. That allows the aircraft to travel faster while using less fuel. Flying at this height also lessens the chance of a plane coming into contact with something else.
Why do airlines fly 36000 feet?
The biggest reason for this altitude lies with fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak. Spending less on fuel is also great for airlines, for obvious reasons.
Why do commercial planes 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. … Also, oxygen starts to become scarce, making it difficult for fuel engine systems to work.
Why do planes fly at 30k?
Most often, commercial airplanes fly anywhere between 30,000 and 42,000 feet in the air, which equals five to seven miles high. Why? The main reason is fuel efficiency. Put simply, airplanes use less fuel in higher altitudes where the air is thinner, increasing the efficiency and saving them money at the same time.
Why do commercial airplanes fly at 36000 feet 11000 km )?
The higher the better
One of the central reasons behind aircraft altitude is that, as the air gets thinner with every foot climbed, planes can travel more easily and therefore move faster and burn less fuel, saving money.
Can 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.
Why do jetliners 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.
Why do planes do not fly over the Pacific?
The primary reason airplanes don’t fly over the Pacific Ocean is because curved routes are shorter than straight routes. Flat maps are somewhat confusing because the Earth itself isn’t flat. Rather, it’s spherical. As a result, straight routes don’t offer the shortest distance between two locations.
What happens if an airplane 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.” …
Why don t commercial jets fly higher?
Carriers avoid a massive amount of turbulence that would occur at lower levels. Along with this, most thunderstorms, severe weather incidents and birds can be avoided while above 35,000 feet. Also, the air is thin enough to reduce the aircraft’s drag, increasing its fuel efficiency.
Can you fly again after ejecting?
Yes, after pulling the ejection handle the entire seat will eject from the cockpit and the pilot will be kept in the seat until the seat knows that it is at a sensible height and speed to then deploy the parachute and initiate the “seat-man separation”; all of the modern Mk.
What is the highest flying plane?
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.
Can you see a plane flying at 30 000 feet?
Here is the theoretical distance you can see from a plane at different altitudes, given perfect weather conditions: at 1000 feet: 38.7 Miles (62km) … at 30,000 feet: 211.3 miles (340 km) at 39,000 feet: 235 miles (391 km)
Can planes fly at 50000 feet?
Answer: Every airplane has a certified maximum altitude. … A: Yes, very high altitude, above 50,000 feet, where there is very little air, has little or no turbulence.
Can you breathe 30000 feet?
Somewhere between 30,000 and 40,000 feet the pressure around you becomes far too low to push those oxygen molecules across the membranes in your lungs, and you get hypoxic (altitude sickness). If you try to breathe 100 percent oxygen above 40,000 feet for very long without a special type of mask, you’ll die.
Do planes fly above clouds?
One reason that planes cruise above the clouds is so they can fly fast. The higher airplanes climb, the thinner the air gets, and the more efficiently they can fly because of less resistance in the atmosphere, according to Ryan Jorgenson, an aviation data analyst.
