Answer: No.The cabin is pressurized between 6,000 and 8,000 feet on long flights. Adding supplemental oxygen is not necessary, because the percentage of oxygen is the same as being on the ground at those altitudes.

The air on a plane contains less oxygen than the air we normally breathe in.This leads to lower levels of oxygen in the blood. If you do not have a lung condition, the drop in oxygen is not enough that you would feel the difference.
On the ground, the airplane is unpressurized and the outflow valve is wide open. During preflight, the pilot sets the cruise altitude on a cabin pressure controller. As soon as the weight is off the main wheels at takeoff, the outflow valve begins to close and the cabin starts to pressurize.
The air on a plane contains less oxygen than the air we normally breathe in. This leads to lower levels of oxygen in the blood. If you do not have a lung condition, the drop in oxygen is not enough that you would feel the difference.
The only oxygen equipment allowed on an airplane is the portable oxygen concentrator (POC). If you need oxygen in flight, you must take a portable oxygen concentrator with you, and , you must let your airline know ahead of time. They may require a doctor's letter to verify the need for the POC on the plane.
If the plane is somehow kept pressurized, the cabin pressure is usually equivalent of 6000–8000 ft, which is lower pressure than the outside at sea level. Which means as soon as you unlock the door, it will swing inwards with a lot of force, as air from outside rushes in to re-pressurize the cabin.
The reduction in air pressure reduces the flow of oxygen across lung tissue and into the human bloodstream. A significant reduction in the normal concentration of oxygen in the bloodstream is called Hypoxia.
If anything happens to the pressurization system, or the plane experiences any difficulties while in flight, oxygen masks will deploy. Oxygen masks supply roughly 10-14 minutes of oxygen, which is more than enough time for a pilot to descend below 10,000 feet, where the atmosphere has enough oxygen.
Masks will automatically drop' And they will. Any cabin depressurization above a certain altitude (usually around 14,000 feet) will cause the panels of the chambers containing the masks to automatically open, and the masks to drop down. This can, of course, be done manually by the cockpit crew as well.
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.
If you're sleeping on a plane, you can't actively work to relax those muscles and release the tension, so you can become susceptible to dizziness, ear infections, eardrum damage, hearing loss and nose bleeds. Wondering about some other health issues flying could cause? Take a look at the dirtiest places in an airport.
Anyone travelling in an aircraft will have a drop in the amount of oxygen getting into their blood, although they are unlikely to feel any different. When you have a chronic lung condition this can make your chest symptoms worse. You may feel more breathless, your chest may feel tight.
While fuel dumps don't happen every day, they're also not uncommon. Nor do they usually represent a major emergency. In fact if an aircraft is taking the time to dump fuel before landing, that's likely an indication that the issue forcing the plane to land is serious but not critical.
Airline pilots take turns using the bathroom nearest the cockpit during a flight. There are no bathrooms installed in the cockpit. For airplanes with a single pilot, diapers, catheters, or collection devices are used if they are unable to land to use the airport bathroom.
It's not uncommon to see planes being sprayed before takeoff. The spray is a heated mixture of glycol and water. It has a lower freezing temperature than just water.This breaks off ice already formed and prevents more from building up.
Use the Valsalva maneuver during ascent and descent.Gently blow, as if blowing your nose, while pinching your nostrils and keeping your mouth closed. Repeat several times, especially during descent, to equalize the pressure between your ears and the airplane cabin.
