Why is there smoke in the cabin of a plane?
Why is there smoke in the cabin of a plane? What you're seeing is mist — hot and humid outside air rapidly condensing upon contact with the aircraft's onboard air conditioning unit that creates billows of water vapor.
At what altitude do planes leave contrails?
Contrails are human-induced clouds that only form at very high altitudes (usually above 8 km - about 26,000 ft) where the air is extremely cold (less than -40°C). Because of this contrails form not when an airplane is taking off or landing, but while it is at cruise altitude.
Do pilots smoke in the cabin?
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 planes fly too 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.
Can pilots hear the cabin?
Do pilots hear the flight attendant announcements? Yes… any announcements made to the passenger cabin, are also heard in the cockpit, and vice-versa. If the cabin crew wishes to speak to the cockpit crew only, they use the phones by the jumpseats or in the galley.
What happens if a plane lands with too much fuel?
If the aircraft tried to land without dumping the fuel first, it is considered an overweight landing attempt and could place immense stress on the airframe. It could also increase the risk of fire and fuel leaking onto the tarmac.
What is the code red on a plane?
9 Code Red They are there to inform people that there is indeed a true emergency on the plane or with it. This is also commonly used in the airport itself. In event of a Code Red, the normal directive is to try and land the plane as best you can at the nearest place you can do so.
Do planes dump fuel every flight?
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.
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.
Can pilots hear flight attendants?
Yes, when the pilot makes the selection to speak on the PA, he will hear if anyone else is using the PA. They would just wait until the other party is finished, or they can take priority and speak over them.
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.
