Here is the theoretical distance you can see from an airplane at various altitudes in perfect weather conditions: at 1000 feet: 38.7 miles (62 km) … at 30,000 feet: 211.3 miles (340 km) at 39,000 feet : 235 miles (391 kilometers)
How far can you see from an airplane at 35,000 feet?
At 35,000 feet the horizon is 221.3 miles away…but the air is probably not clear enough for you to actually see far enough in the day to spot it. Normally, the humidity in the air creates haze and makes it impossible to see it except in very dry cold air, like in the polar regions.
How high in the sky can you see an airplane?
Under ideal conditions, it is limited by the angular resolution of the eye, which is 0.02° and corresponds to 0.3 m at 1 km. If the plane has a wingspan of 15m, the average person should only be able to see it from 45km away, they wouldn’t be able to tell it’s a plane, just a faint spot.
Can you hear an airplane at 30,000 feet?
Yes . It can even be heard at 30,000 feet.
Can you see a plane 40,000 feet away?
Modern commercial aircraft are typically built to operate at altitudes in excess of 40,000 feet. … The service ceiling is the maximum density altitude that an airliner can attain according to its design. However, travelers are more likely to be airborne at a cruising altitude of about 35,000 feet.
Can you see an airplane at 35,000 feet above the ground?
This information is really rare to find anywhere in the literature, and I suppose more experienced pilots can answer it better, but my answer would be: the size of the plane is the key factor, because if a plane were flying in 35,000 feet, that’s what it would do hardly noticeable even in clear weather…
How far can you see at 37,000 feet?
235 miles The line of sight of an airplane at 37,000 feet = 235 miles. It is only about 3.4 degrees from Earth’s surface. From the ISS at 250 miles, the line of sight is 1,435 miles, covering about 19.8 degrees of the Earth’s surface, which is much easier to see the curve from that altitude.
Can you see a plane 40,000 feet away?
Modern commercial aircraft are typically built to operate at altitudes in excess of 40,000 feet. … The service ceiling is the maximum density altitude that an airliner can attain according to its design. However, travelers are more likely to be airborne at a cruising altitude of about 35,000 feet.
Can you see planes from the ground?
Depending on the size of the aircraft, without the contrails to give away its presence, you can likely see an airliner at an altitude of 7,500 to 10,000 feet. A smaller light aircraft probably up to about 5000.
How far can you see a fighter plane?
You can easily see it flying at cruising altitude, if it were directly overhead it would be 35-40,000 feet or about 7 miles high. If it’s at a 45 degree angle to you and the ground and cruise altitude, it’s 10-11 miles.
How far in the sky can an airplane fly?
All aircraft have a designated service ceiling that defines the maximum altitude at which they must operate. For most modern commercial aircraft today, that’s about 41,000 feet. The exact level depends mainly on the power of the engines (it is designed to be the maximum that still allows efficient operation).
How far do planes fly above the clouds?
According to USA Today, the usual cruising altitude for most commercial aircraft is between 33,000 and 42,000 feet, or about six to almost eight miles above sea level.
How far can you hear an airplane?
The answer is a very rough estimate! In normal weather conditions it is about 50 to 60 kilometers. This answer is very relative and it is important to note that it depends on geographical and meteorological conditions. The plane itself is only visible from about 10-15 km away.
Can you hear an airplane 35,000 feet above the ground?
~31s. This means you might hear the plane but not see where the sound is coming from. Note that this is not an exact value as the speed of sound varies with air density and temperature, both of which change as you ascend.
Can you see an airplane 30,000 feet above the ground?
When it comes to commercial aircraft, they are typically at their cruising altitude of over 30,000 feet. Depending on the size of the aircraft, without the contrails to give away its presence, you can likely see an airliner at an altitude of 7,500 to 10,000 feet. A smaller light aircraft probably up to about 5000.
Can you breathe at 35,000 feet?
You can breathe at 35,000 feet without a pressure suit, but go much higher and you can’t. …Oxygen makes up 21% of the air mixture, so you have an O2 partial pressure of 160 mmHg. At 35,000 feet, the atmospheric pressure is 179 mmHg [1]. So when you breathe 100% pure oxygen, you get the same amount of oxygen as you would at sea level.
How far can you see from 40,000 feet?
So at 10,000 feet you can see 122 miles, at 30,000 feet you can see 211 miles, and at 40,000 feet you can see 244 miles.
At what altitude can we see planes?
When it comes to commercial aircraft, they are typically at their cruising altitude of over 30,000 feet. Depending on the size of the aircraft, without the contrails to give away its presence, you can likely see an airliner at an altitude of 7,500 to 10,000 feet. A smaller light aircraft probably up to about 5000.
Can a human survive at 40,000 feet?
Even at 40,000 feet, the time a passenger would be exposed to a cabin altitude higher than the yellow emergency masks could withstand is about 90 seconds. In other words, you’re likely to pass out on an emergency descent without a pressurized respirator descending from 40,000.
