That’s nearly 7 miles up in the air. However, the number generally varies from about 33,000 feet to 42,000 feet. Private jets typically take the higher end, cruising at around 41,000 feet so they can travel the most direct route, above all the commercial air traffic. Light aircraft typically stick close to 10,000 feet.
How high do prop planes fly?
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. Planes can fly much higher than this altitude, but that can present safety issues.
How high can turboprops fly?
It is a matter of power source (and engine aspiration in case of air breathing engines), wing loading and aerodynamic efficiency. With current technology, the limit is around 100.000 ft (30 km), as proven by Pathfinder and especially Helios.
Can planes fly at 50000 feet?
Many business jets can travel even higher, at 50,000 feet, due to having large engines for the small size of the aircraft. … However, many light aircraft have to cruise below 10,000 feet because they don’t have the luxury of pressurized cabins like jetliners.
How high can a small plane fly?
These aircraft are designed to fly in “the flight levels,” which in common practice really refers to cruising higher than about 20,000 feet above sea level. (For purposes of this article, all altitudes will be given above sea level.) The cruise portion of most airline flights take place between 30,000 and 40,000 feet.
Do planes fly over Everest?
Airplanes often avoid air paths that take them over Mt Everest or the Pacific Ocean. … This is because “the Himalayas have mountains higher than 20,000 feet, including Mt Everest standing at 29,035 feet. However, most commercial airplanes can fly at 30,000 feet.”
What happens if a plane 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 can’t turboprop fly at high altitudes?
A bit of an over simplification, but turboprops don’t fly that high because their propellers aren’t as efficient in the thinner air as jets. So they’re stuck down in the thick air and the weather and turbulence and ice producing clouds. Turbofan engines are more efficient at higher altitudes.
Are turboprops safer than jets?
Turboprop vs Jet Safety
Both turboprops and jets are powered by turbine engines, so they are essentially the same thing and thus, are considered to be equally as safe. … Turboprops and jets are considered safer, and especially those with twin engines.
Why are turboprops still used?
Originally Answered: Why do some planes still use propeller engines, not jets? Turboprops are more fuel efficient than jets. So, if you don’t need max speed, use a prop. Airlines have other expenses besides fuel, which cost more per hour than the fuel, so they run jets to minimize the non-fuel expenses.
What is the highest a plane has ever flown?
On February 17, 1986, The highest altitude obtained by a soaring aircraft was set at 49,009 ft (14,938 m) by Robert Harris using lee waves over California City, United States.
What is the highest altitude a plane 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. The highest business jet flying today reaches 51,000 feet.
How far can a pilot see at 35000 feet?
If you look up into space you are looking through about 62 miles of atmosphere, at 35,000 feet you will be looking through almost 230 miles of atmosphere to see the horizon.
Do pilots sleep while flying?
The simple answer is yes, pilots do and are allowed to sleep during flight but there are strict rules controlling this practice. Pilots would only normally sleep on long haul flights, although sleep on short haul flights is permitted to avoid the effects of fatigue.
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.
How cold is it at 35000 feet?
How cold is it up there? The higher you get, the colder it gets, up until 40,000 feet. If the temperature at ground level was 20C, at 40,000 feet it would be -57C. At 35,000 feet the air temperature is about -54C.
