What is the white stuff that comes out the back of a plane?


What is the white stuff that comes out the back of a plane? These clouds are contrails, short for condensation trails. Water vapor is one of the byproducts of jet fuel combustion and will turn into ice crystals in the cold air at the high elevations where jet airplanes fly. Those ice crystals create a cloud (the contrail), which does not pose any public health risk.


Is there smoke in the plane before takeoff?

One of the many mysteries of air travel is the white mist that occasionally fills the airplane cabin right before takeoff. AFAR explains the science involved. Condensation is caused by the difference between temperatures outside and inside the plane.


What is the germiest place on a plane?

According to flight attendant Brenda Orelus, the dirties place on an airplane is not the lavatory or the tray tables. It is the seat-back pockets. IN a video that Orelus posted on TikTok she revealed to her more than 100,000 followers that the pockets are full of germs and are almost never cleaned.


Is it bumpy at the back of a plane?

Seats at the back of the plane tend to be bumpier, and sitting towards the back also means you're one of the last passengers to get off the plane after landing. Similarly, the bulkheads at the front of the cabin are where families with babies and young children sit.


Do planes dump fuel in the ocean?

The good news is that pilots are supposed to dump fuel at a safe height above the ground and away from other aircraft, and in addition, over as remote an area as possible. In the case of Heathrow, for example, most fuel dumps have occurred over the sea.


How high do planes fly?

According to USA Today, the common cruising altitude for most commercial airplanes is between 33,000 and 42,000 feet, or between about six and nearly eight miles above sea level. Typically, aircraft fly around 35,000 or 36,000 feet in the air. To put that in perspective, the peak of Mount Everest measures 29,029 feet.


Do planes dump fuel before landing?

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.


Do pilots sleep on long flights?

The simple answer is yes, pilots do, and are allowed to sleep during flight but there are strict rules controlling this practice. Pilots would only normally sleep on long haul flights, although sleep on short haul flights is permitted to avoid the effects of fatigue.


Why is vaping not allowed on planes?

Electronic smoking devices, like vapes and e-cigarettes, contain lithium batteries and are considered dangerous goods due to their risk of smoke, fire and extreme heat. As such, they are restricted to on how they can be packed when preparing for travel on an aircraft.


Do pilots smoke in the cockpit?

Pilots can and sometimes do smoke in the cockpits of business jets. These can be as large as airliners (see BBJ), but usually aren't. Even when a country and/or airline ban smoking in the flight deck, some pilots will ignore the ban and still light up.


What happens if you get caught vaping on a plane?

The fine for smoking or vaping on a flight can range from $2 to $4,000, and by itself is not a jailable offense. However, it can quickly escalate if a person is found to have tampered with a smoke detector, or failed to comply with a crew member's instruction, such as to stop smoking.


Why do planes fly so high?

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.
