Why do most commercial airplanes fly at around 35000 ft?

So there has to be a balance, which is the reason for the fairly specific altitudes generally used by airliners. 35,000 feet or thereabouts is the altitude at which fuel efficiency is greatest, while there is still enough oxygen available to power the engines.

The biggest reason for flying at higher altitudes lies in fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak.

Flying higher means planes can avoid birds (usually), drones, and light aircraft and helicopters, which fly at lower altitudes.

The sweet spot of flying is regarded as between 35,000 and 42,000 feet (the airline industry still uses feet and inches as its standard measurements) – too high and the oxygen becomes too sparse to fuel the engines, too low and the air resistance is greater.

There are no specific regulations governing civil aircraft operations beyond the altitude of 60,000 feet. Nevertheless, certain exceptional aircraft like the Concorde and the Tupolev Tu-144 have managed to ascend to altitudes of FL600 (equivalent to 60,000 feet).

Severe turbulence, he added, is “quite rare — only 0.1% of the atmosphere at 40,000 feet has severe turbulence in it, so if you're on a plane it's very unlikely that your plane will hit that 0.1%.” “However, given the number of planes in the skies, one of them will.

A: No commercial or business airplane flying today can exceed 100,000 feet. Special rocket-powered airplanes can fly over 100,000 feet to gather data, but they are specially designed for it.

For Part 91 General Aviation operations the required flight crew must use supplemental oxygen for any portion of the flight that exceeds 30 minutes above a cabin pressure altitude of 12,500 feet mean sea level (MSL) up to and including 14,000 feet (MSL).

Planes have lower oxygen levels If this didn't happen, everyone inside the plane would die, as the low air pressure at the elevations planes fly (typically 35,000 feet or so) means there isn't enough oxygen present for your body to function.

Whether flying at night or during the day, pilots need to see some kind of horizon. They use this to determine the airplane's attitude. At night pilots will turn their gaze from outside to inside and use the artificial horizon. The artificial horizon is normally a simply globe split into two hemispheres.

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.

The bigger the plane, the better! Any plane can experience turbulence, but larger planes weigh more and don't feel the impact of wind changes as much as a smaller plane. Specifically, the Airbus A380 handles turbulence very well! The A380 is a large plane mainly used for international flights.

Very rarely, turbulence can cause a change of a few hundred feet, but most times it is less than 100 feet.

So what's the best altitude to minimize your exposure to moderate or greater turbulence? Well, considering both in-cloud and out-of-cloud turbulence, flight between 8,000 and 12,000 feet will allow for the smoothest ride, on average.”

white was the first pilot to fly any aircraft faster than mach 4, 5 and 6, as well as the first to fly above 200,000 and 300,000 feet. he set the only official world record of the X-15 program when he flew to 314,750 feet on July 17, 1962, a f?d?ration a?ronautique internationale altitude record that still stands.

Aerodynamic altitude: If a commercial airliner flies too high, it will encounter less dense air passing over the wings to create lift. This can cause the plane to stall and fall out of control. Depending on the weather conditions and aircraft weight, this can occur anywhere between 40,000 and 45,000 feet.

Jet streams, which are a system of air currents that circle the Earth many miles above the planet's surface, are another reason why aircraft don't fly over the Pacific Ocean. Due to Earth's rotation, these air currents often move from West to East.
