How cold is the air at 38000 feet?
How cold is the air at 38000 feet?
With an increasing altitude, it gets colder, and the average temperature at 38000 ft. is around -54 (-65 F).
How cold is the air at 35000 feet?
negative 60 degrees Fahrenheit
At 35,000 ft. (11,000 m), the typical altitude of a commercial jet, the air pressure drops to less than a quarter of its value at sea level, and the outside temperature drops below negative 60 degrees Fahrenheit (negative 51 degrees Celsius), according to The Engineering Toolbox.
Can you breathe at 38000 feet?
How dangerous are the conditions? Very. At 38,000 feet — the cruising altitude of the Hawaiian Airlines flight that the FBI says the 15-year-old took Sunday — the outside air temperature is about minus 85 degrees. The air is so thin that a person will pass out because the brain is starved of oxygen.
What is the air temperature at 36000 feet?
For example: at 36,000 feet the standard outside air temperature is -56.5°C (-69.7°F) and is well below Jet-A’s freezing point of -40°C/F.
Can you breathe at 36000 feet?
There is an altitude range, however, where even breathing 100 percent oxygen (with 100 percent partial oxygen pressure) from a little yellow mask in a jetliner won’t provide enough life-sustaining oxygen saturation in the bloodstream. That point is around 28,000 to 30,000 feet.
How cold is it at 37000 feet?
The Troposphere is closest to the surface of the earth, and as you climb into it, on average, the temperature decreases by roughly 3.6°F for every 1,000 feet. This means that at cruising altitude of 37,000 feet, the outside air temperature could be minus 76°F.
Why do planes fly at 37000 feet?
The biggest reason for this altitude lies in 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.
How cold is it at 37 000 feet?
The Atmosphere The Troposphere is closest to the surface of the earth, and as you climb into it, on average, the temperature decreases by roughly 3.6°F for every 1,000 feet. This means that at cruising altitude of 37,000 feet, the outside air temperature could be minus 76°F.
What is the temperature at 40000 ft?
around -70 degrees Fahrenheit
But it isn’t the cold that’s a problem for most aircraft. After all, commercial airplanes can cruise at an altitude of nearly 40,000 feet, where temperatures hover around -70 degrees Fahrenheit.
Why do planes avoid flying over Pacific Ocean?
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.
Can you breathe at 40000 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.
