Commercial aircraft typically fly between 31,000 and 38,000 feet — about 5.9 to 7.2 miles — high and usually reach their cruising altitudes in the first 10 minutes of a flight, according to Beckman.
Do planes fly at 8000 feet?
Most commercial aircraft are pressurized to 6,000 to 8,000 feet , not sea level.
Can you breathe at 35000 feet?
Whether you are flying aboard a small Cessna or a jumbo-sized Airbus A380, you can breathe freely inside the cabin without wearing a mask or respirator. Even at a cruising altitude of 35,000 feet, you shouldn’t have trouble breathing .
Can a plane fly over Mount Everest?
The first men to fly over Mount Everest did so in an unpressurized biplane . The two planes fly towards Lhotse and Everest at 32,000 feet. Though the 29,029-foot-high summit of Mount Everest was first conquered on foot by Tenzing Norgay and Edmund Hillary in 1953, it was conquered by air two decades earlier.
What happens if a jet 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 a plane fly at 60000 feet?
Question: What is the highest altitude an airplane 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.
HOW HIGH CAN military jets fly?
Most military planes fly at around 50,000 feet and sometimes higher . Some rocket-powered planes can fly as high as 100,000 feet but they are specially designed for this purpose.
Why do private jets fly so high?
A private jet can fly at a height of up to 45 000 ft, though most cruise at 41 000 ft. This is generally higher than an airline flight and allows for a more direct route – out of the most congested area of the sky . A private jet pilot will choose the optimum cruising altitude depending on the distance of the journey.
At what height is there no oxygen?
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).
How cold is it at 50000 feet?
| Geo-potential Altitude above Sea Level – h – (ft) Temperature – t – ( o F) Acceleration of Gravity – g – (ft/s 2 ) | 45000 -69.70 32.036 | 50000 – 69.70 32.020 | 60000 -69.70 31.990 | 70000 -67.42 31.959 |

Why do planes avoid flying over Pacific Ocean?
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.
How high can helicopters fly?
Turbine-engined helicopters can reach around 25,000 feet . But the maximum height at which a helicopter can hover is much lower – a high performance helicopter like the Agusta A109E can hover at 10,400 feet.
Why can’t planes fly over Antarctica?
What is this? The polar regions interfere with magnetic navigational equipment, making it harder for planes to navigate . It can also be difficult for planes to connect with flight controllers because of the location’s isolation.
Can a dog climb Mount Everest?
In fact, the 8-month-old mixed-breed dog has become the first dog in recorded history to reach the Mount Everest Base Camp . Rupee’s ascent is no small feat — the Everest Base Camp sits at a whopping altitude of 17,598 feet.
Can a plane accidentally fly into space?
Cars, trucks and SUVs all use air as part of their combustion process. If an airplane flies in space, it won’t be able to suck in fresh air with which to supply its engines, resulting in loss of propulsion. The bottom line is that airplanes can’t fly in space because there is no air in space .
What happens if a plane window breaks?
A broken window would cause the air inside to rush out rapidly, causing little objects like phones and magazines (and even larger ones, like people) to be carried away . It’s also possible to experience lower temperatures and lower air pressure, and mist or fog from condensation inside the plane.
What happens if an airplane is struck by lightning?
When an airplane is hit, the pilot will determine whether it’s safe for the flight to continue . If not, the plane will divert to inspect the aircraft for damage and make repairs if necessary.
Can planes fly 70000 feet?
It provides day and night, high-altitude (70,000 feet, 21,300 meters) , all-weather intelligence gathering. Lockheed Corporation originally proposed it in 1953, it was approved in 1954, and its first test flight was in 1955. It was flown during the Cold War over the Soviet Union, China, Vietnam, and Cuba.
How high can a 747 fly?
Boeing 747
Lufthansa previously bragged that its 747-400 could reach the highest altitude in its fleet, reaching a max altitude of 44,947 ft (13,610 m) . Meanwhile, the modern 747-8, which is well deployed by the carrier, has a service ceiling of 43,100 ft (13,137 m).
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. Commercial airplanes can climb to 42,000 feet, but going beyond that can be precarious, as the air starts to become too thin for optimum flight of the airplane.
How high can birds fly?
Many bird species live in habitats that are over 13,123 feet (4,000 m) above sea level, and others routinely fly to altitudes of approximately 10,000 to 13,000 feet (3,000 to 4,000 m) , especially when they’re migrating, said Graham Scott, an assistant professor of biology at McMaster University in Ontario, Canada.
How high can f15 fly?
| First flight July 27, 1972 | Length 63 feet 9 inches | Height 18 feet 8 inches | Ceiling 65,000 feet | Range 2,400 miles |

What is the highest a plane has ever flown?
On July 17, 1962, American test pilot Robert White took the X-15 to an altitude of 314,688 feet. But it’s Russian pilot Alexandr Fedotov who holds the world altitude record, set on August 31, 1977, when his MiG E-266M reached a mere 123,523 feet .
Do empty planes fly faster?
Passenger weights are a part of the overall weight, hence the fewer passengers, the less the weight. Lighter airplanes lift off the runway at a lower speed, climb faster, cruise higher and land at a slower speed.
At what altitude do most commercial planes fly?
But there are good reasons for how high planes fly. In fact, the common cruising altitude for most commercial airplanes is between 33,000 and 42,000 feet , or between about six and nearly eight miles above sea level. Typically, aircraft fly around 35,000 or 36,000 feet above sea level.
How much faster are jets than planes?
Private jets often fly at the same speed as commercial jets, which on average, fly 547–575 mph when they reach cruising altitude. Smaller private jets and private aircraft, on the other hand, often have the capability of flying faster than commercial airplanes .
