What are the disadvantages of flying high?
What are the disadvantages of flying high? 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.
Why do commercial airlines not fly higher?
Because the higher you go, the thinner the air, going too high can make it tough to keep the plane in the air. Why? There will not be enough lift to do so. Above 25,000 feet or so, air pressure begins to drop.
At what altitude do you need oxygen?
For best protection, you are encouraged to use supplemental oxygen above 10,000 feet MSL. At night, because vision is particularly sensitive to diminished oxygen, a prudent rule is to use supplemental oxygen when flying above 6,000 feet MSL. So, when you fly at high altitudes, supplemental oxygen is the only solution.
Do planes fly over Mount Everest?
Why Mount Everest is a no-fly zone - The Hindu BusinessLine.
What is a safe flight height?
An altitude of 500 feet above the surface, except over open water or sparsely populated areas. In those cases, the aircraft may not be operated closer than 500 feet to any person, vessel, vehicle, or structure.
What do pilots see when flying?
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.
