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.
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.
What is the max altitude for a helicopter?
The maximum altitude which can be reached during forward flight typically depends more on the ability of the engine to breathe the thinner air than the rotor’s ability to provide lift. Turbine-engined helicopters can reach around 25,000 feet.
What is the highest altitude A fighter jet can fly?
Most US military aircraft can exceed 50,000 feet, if they really really try. Again, the limits are classified. Most commercial jetliners cruise somewhere between 30,000 and 45,000 feet above mean sea level.
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.
Do pilots get altitude sickness?
Airplanes fly at very high altitudes of up to 30,000 to 45,000 feet. The cabin air pressure in an airplane is adjusted to compensate for these high altitudes. The oxygen level is comparable to levels found in elevations of 5,000 to 9,000 feet. Both men and women can get altitude sickness.
How high can you fly without pressurization?
The higher the maximum differential pressure, the closer to sea level the system can maintain the cabin. Federal Aviation Regulations say that without pressurization, pilots begin to need oxygen when they fly above 12,500 feet for more than 30 minutes, and passengers have to use it continuously above 15,000.
Can you fly a helicopter to the top of Mount Everest?
Everest. Straddling the border of Nepal and China stands the world’s highest mountain: Mount Everest.
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.
Can helicopters fly in rain?
Helicopters can fly just fine in the rain, and in conditions way worse than prevailed in Paris on November 10. First, about helicopters and weather. … There is nothing special about the rain-worthiness of the helicopter any president normally uses. In principle, any helicopter can fly in clouds or rain.
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.”
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.
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.
What happens if 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.” …
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.
Which is better turboprop or jet?
A turbine engine is extremely light and produces tremendous power-to-weight as opposed to a comparable piston engine. … Conversely, jet engines are less efficient than a turboprop but often make up for it by being faster, hence spending less time in the air for the same destination.
