Why do aircraft fly at 35000 feet?

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.

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.

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).

Airlines these days cruise at around 35,000 feet, some higher and some lower, but without protection at these altitudes a human being cannot survive.

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 most common reason is that there are no airstrips or airports on many of the small islands, so if a plane had to make an emergency landing, it would be difficult to find a place to land. Additionally, the Pacific Ocean is vast and remote, so if a plane were to go down, it would be very difficult to find.

All airplanes will be exposed to drag during flight. They must overcome this aerodynamic force to achieve and maintain lift. Otherwise, airplanes would essentially fall out of the sky. Air brakes are control surfaces that increase drag so that airplanes slow down during flight.

At 25,000 feet the average EPT is 3 to 5 minutes. After about 20 minutes without supplemental oxygen, you will be pronounced dead.

Death zone 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).

Low air pressure during air travel also decreases the amount of oxygen in the air. This effect is modest and generally not noticeable for healthy travelers. For patients with significant lung disease, a small decrease in available oxygen can cause significant symptoms, especially with exercise.

When the altitude of an airplane is less than 12,500 feet, there is no supplemental oxygen required for anyone in a private plane. From 12,500 feet to 14,000 feet, supplemental oxygen must be used by the required flight crew for any portion of the flight that is more than 30 minutes.

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.

A: During certification testing, airplanes are flown above the certified ceiling, but the performance is limited.
