He goes on to explain that at around 6,000 to 8,000 feet airplane, cabins become pressurized. “Air expands at higher altitudes, the gas in our intestines expands too, up to 30 percent more than usual and that air needs to go somewhere,” he says.

Fuel dumping (or a fuel jettison) is a procedure used by aircraft in certain emergency situations before a return to the airport shortly after takeoff, or before landing short of the intended destination (emergency landing) to reduce the aircraft's weight.
Airlines find that fuel dumping can actually be cheaper than not dumping in certain circumstances. But it's not something pilots do on a routine basis. We spoke with Alison Duquette, spokesperson for the Federal Aviation Administration (FAA), who assured us that it doesn't happen very often.
In most cases, airlines only dump air in midair immediately before landing. They don't do it before or during takeoff, nor do they do it halfway through their flight. Rather, airlines may dump some of their airplane's excess fuel immediately before landing so that it lowers the weight of their aircraft.
Airplane ear occurs when the air pressure in the middle ear and the air pressure in the environment don't match, preventing your eardrum (tympanic membrane) from vibrating normally. A narrow passage called the eustachian tube, which is connected to the middle ear, regulates air pressure.
The short answer is that, under most conditions, the shelf life of avgas is about one year. If you are a commercial operator, this is the end of the discussion. For a private pilot, however, there are several points to consider. First, there is a large margin of safety in the one-year storage life of avgas.
Emissions from aviation are a significant contributor to climate change. Airplanes burn fossil fuel which not only releases CO2 emissions but also has strong warming non-CO2 effects due to nitrogen oxides (NOx), vapour trails and cloud formation triggered by the altitude at which aircraft operate.
Regarding an aviation accident, a ghost plane or ghost flight occurs when the plane, already in the air, suffers some type of accident that has incapacitated the crew and passengers but continues to fly until it runs out of fuel and crashes.
