It's for your own safety. If anything happens during take-off and landing - the most risky stages of every flight - then your eyes will already be used to the dark or the light outside, and you'll be able to react more quickly. That's also the reason why the lights in the cabin are dimmed for take-off and landing.
This is to assist the crew in case of an emergency, so they can see out of the aircraft in case of an evacuation. Most accidents happen during take off or landing so this makes complete sense.
This is a safety measure, and is to ensure your eyes are adjusted to the gloom enough to see the floor lights leading you to safety along the aisle in the event of a crash or emergency evacuation. If the cabin lights were on, but then went out your eyes would need a while to adjust to the lower light levels.
Opening the window
When the aircraft is not pressurized, either on the ground or if depressurized during the flight (intentionally or due to an accident), then pilots can open them. On most modern aircraft, the opening procedure is the same.
They may hear strange noises, but they won't be able to see hazards involving the airplane's wings or its surrounding environment. As a result, airlines require passengers to open their window shades during takeoffs and landings. If something goes wrong, passenger may spot it.
So the lifting of the window shades makes it possible for emergency personnel stationed outside of the aircraft to see into the cabin in order to assess a potential evacuation situation.
Pilots have a unique viewpoint while flying private or commercial aircraft. They get an unobstructed view of stunning natural sights, such as pink lakes and rectangular-shaped icebergs. Some have reported seeing UFOs, while others have flown over swirling hurricanes.
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.
Federal Aviation Regulations require that a pilot's distant vision be 20/20 or better, with or without correction, in EACH eye separately to hold a first or second class medical certificate. The standard for near visual acuity (16″) is 20/40 in each eye separately.
During takeoff, air accelerated behind the prop (known as the slipstream) follows a corkscrew pattern. As it wraps itself around the fuselage of your plane, it hits the left side of your aircraft's tail, creating a yawing motion, and making the aircraft yaw left.
Night flying restrictions or night-time curfews, including night flight bans, are any regulations or legislation imposed by a governing body to limit the ground-perceived exposure to aircraft noise pollution during the night hours, when the majority of residents are trying to sleep.
While night flying brings certain concerns into play, it also offers numerous benefits for pilots. As daylight heating gives way to nighttime cooling, the air generally becomes smoother and convective weather dissipates, providing a better ride for passengers and less work for pilots.
These tiny holes, also called breather holes, serve as a safety function, by making sure that the outer pane bears all the air pressure (the pressure inside the cabin is much higher than outside). This also ensures that in case the pressure difference becomes high enough, it is the outer pane that breaks off first.
In the case of the engine loss itself, the problem was not all that dire. In fact, airliners can fly quite well on just one. The Boeing 777 is certified to fly up to five and a half hours with one engine out.
The cockpit glass is just like the windshield in your car; if you can see something directly, you will see it in the cockpit. You will also see the small cracks in the windshield, especially when sunlight is directly shinning at it. This is a natural property of the material used.
Singapore Airlines has held the record for world's longest flight since 2016. Their trip from Singapore to New York is more than 9,500 miles.
Weather and jet streams
So, this is yet another reason why most routes avoid flying over the Pacific since it can be a sort of wild west of weather.
The primary reason airplanes don't fly over the Pacific Ocean is because curved routes are shorter than straight routes. Flat maps are somewhat confusing because the Earth itself isn't flat.
“Ladies and gentlemen, we have begun our descent into [city]. Please turn off all portable electronic devices and stow them until we have arrived at the gate. In preparation for landing in [city], be certain your seat back is straight up and your seat belt is fastened.
Aircrafts don't really have headlights per se; but, There are red and green LEDs outside of the aircraft and on the ground, which help the pilots land at night and make their aircraft visible to another aircrafts in the night sky.
"So when you're walking on the airplane and you see our happy, smiley face, we're actually looking you up and down and we are trying to find our ABS and what that is called is our Able-Bodied People, or person," Kalamani says. "So this is people who are going to help us in an emergency."
The FAA requires that seat backs be upright for take off and landing to provide as much room as possible for the people behind you to get to the aisle in the event of an emergency evacuation. This requirement has been in place for decades.
Concorde. The Concorde was a supersonic jet that could fly at speeds of up to 1,354 mph (2,179 km/h), making it the fastest commercial airliner ever built.
Carriers such as JetBlue, Southwest, United Airlines, and Delta tell travelers that they may use wireless accessories like bluetooth headphones and keyboards during flight as long as they're on flight mode, meaning any cellular service is deactivated and they're using wi-fi instead.
