What are the dangers of flying at high altitude?


What are the dangers of flying at high altitude? As the partial pressure of oxygen in inspired air continues to drop with increasing altitude, signs and symptoms of hypoxia become more evident, and include loss of peripheral vision, skin sensations (numbness, tingling, or hot and cold sensations), cyanosis, euphoria, and eventually unconsciousness at higher altitudes ...


How high is too high to fly?

Some business jets can soar up to 15,000 meters, while most military aircraft can fly at this altitude or even a little higher. However, these aircraft tend to stay below 15,000 feet for safety reasons, as the air can become too thin and make it impossible to burn aviation fuel continuously.


How slow can a plane fly without falling?

Technically this is the so-called 'stall speed', where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph). But at such low speeds, the aircraft is easily destabilised, and could fail to leave the runway.


How long can a plane stay in the air without engines?

Flying at a typical altitude of 36,000 feet (about seven miles), an aircraft that loses both engines will be able to travel for another 70 miles before reaching the ground.


What conditions will planes not fly in?

Flights may be canceled due to wind, precipitation, fog or low visibility, lightning, low clouds, or storms.


What is the safest altitude to fly?

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.


Why do 99% of planes not fly over Pacific Ocean?

Because of its vast size, crossing the Pacific Ocean requires a staggering quantity of fuel. However, most commercial aircraft do not fly directly over the Pacific Ocean; instead, they choose what are known as 'curved paths'. These paths offers a faster, more efficient route given the curved nature of the earth.


Which flight has the most turbulence?

Routes with the Most Turbulence
  • New York to London.
  • Seoul to Dallas.
  • Flying into certain airports near the equator. There are certain airports which are located close to the equator which means frequent thunderstorms, especially in certain seasons. ...
  • Flying into Reno, Nevada. ...
  • London to South Africa.


What is jet belly?

Jet belly: (noun) the bloated state in which your stomach inflates post-flight. Also, a very unpleasant feeling. May also make you look like you're 3 months pregnant. So how does one prevent this jet belly? Well, it all depends on what you eat on the plane.


Why do planes drop suddenly?

When an aircraft experiences turbulence, the plane can drop or change altitude suddenly. This is why pilots always caution passengers to buckle up and stay seated when they are experiencing flight turbulence. The sudden movements put passengers at risk.


Can flights stop in air?

Yes, an aircraft can stay in the air without going forward if the oncoming wind, called headwinds are equal or greater than th minimum speed of that aircraft. This principle is used in the wind tunnels to experiment the flight characteristics by blowing the wind to the aerofoil and assess the aerodynamic changes.


When shouldn t you fly?

recent operation or injury where trapped air or gas may be present in the body (e.g. stomach ,bowel, eyes, face, brain) severe long term diseases that affect your breathing. breathlessness at rest. unresolved pneumothorax (punctured lung)


Why do planes fly north to go to Europe?

That's because it is, and there is a very simple reason for it. Despite what many people believe, the answer actually has nothing to do with safety. The real answer is because going north may actually provide a shorter route. This is called Great Circle Navigation.


What is the longest flight in the world?

What is the longest flight in the world by distance? The longest flight in the world by distance is New York (JFK) to Singapore (SIN) on Singapore Airlines clocking in at 9,537 miles. What plane can fly the farthest in the world?


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.


What do pilots do during turbulence?

At times like this, pilots will slow to a designated “turbulence penetration speed” to ensure high-speed buffet protection (don't ask) and prevent damage to the airframe. We can also request higher or lower altitudes, or ask for a revised routing.
