What is the temperature at 30 000 ft?
A: The standard temperature for 30,000 feet is -44.5C or -48F (Source: meteorologytraining.tpub.com/14269/css/14269_75.htm). All materials used in airplanes are designed and tested to withstand temperature extremes.
What is the temperature at 31000 feet?
U.S. Standard Atmosphere Air Properties – Imperial (BG) Units
| Geo-potential Altitude above Sea Level – h – (ft) | Temperature – t – (oF) | Acceleration of Gravity – g – (ft/s2) |
|---|---|---|
| 30000 | -47.83 | 32.082 |
| 35000 | -65.61 | 32.066 |

How cold is the air at 32000 feet?
Between 30,000 and 40,000 feet (9,000 and 12,000 m), the cruising altitude of most jet aircraft, air temperature ranges from -40° F to -70° F (-40° C to -57° C). Modern aircraft have sealed cabins and heaters to protect pilots and passengers from wind blast and cold air.
What is the temperature at 40000 feet altitude?
After all, commercial airplanes can cruise at an altitude of nearly 40,000 feet, where temperatures hover around -70 degrees Fahrenheit.
At what temp does jet fuel freeze?
-47 degrees C.
Jet A-1 is a kerosine grade of fuel suitable for most turbine engined aircraft. It has a flash point minimum of 38 degrees C (100°F) and a freeze point maximum of -47 degrees C.
How long does it take to fall from 30 000 feet?
When you’re in free fall from 9,144 meters (30,000 feet) in the air, a soft landing is probably the last thing on your mind. It all happens so fast. From the moment you’re outside of the plane, it’s only about 170 seconds until you hit the ground.
What’s the air temperature at 36, 000 feet?
On aircraft which fly above 30,000 feet, the temperature can often can get to temperatures below Jet-A’s freezing point. 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.
What’s the temperature at the equator at 50k ft?
Therefore you would expect a tropopause at 50k ft for equator with temperature around -75 C, while it might be around 36k ft at the poles and the temperature be around -50 C here. Hope this helps.

How many degrees Fahrenheit do you lose at altitude?
You will lose an average 3.5 degrees Fahrenheit for every 1000 feet of elevation you gain (or about 1.2 degrees Celsius per ever 100 meters. Some people use 9.8 degrees Celcius per 1000 meters). How do I calculate altitude?
What’s the normal saturation of air at 10, 000 feet?
At 10,000 feet above sea level, the normal saturation for a human breathing regular air is 87 percent. That point is around 28,000 to 30,000 feet. Can jet fuel freeze?
