Why are airplane windows kept open during takeoff?

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.

Changes were made to cockpit security in order to make hijackings more difficult. The US Federal Aviation Administration recommends that doors be strong enough to withstand a grenade blast. Also, they are usually left locked for the duration of the flight.

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.

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.

At cruising altitude, the pressure outside a plane is around two-and-a-half times lower than inside the cabin, so a broken window or a large hole in the fuselage can be catastrophic, causing a blast of air that will suck out seats as well as people.

“The armrest could slam into your side with a force as if it was travelling at more than 135 knots (250km). It's important for your safety to put your armrest down during takeoff and landing.

By moving the yoke several times per second, pilots can react quickly to any changes in external conditions such as wind gusts or turbulence which could affect their approach path or descent rate.

1. Can a passenger plane fly with just one wing or upside down? “An airplane cannot stay in the air with just one wing. Both wings are necessary to provide enough lifting power for the plane to stay in the air.

A headwind will reduce the ground speed needed for takeoff, as there is a greater flow of air over the wings. Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph). Light aircraft, such as a Cessna 150, take off at around 100 km/h (54 kn; 62 mph).

Passengers often ask for pens when they have to fill in their immigration cards and of course, you never see the pen again, so it's always better to have some extras.

As the tail comes up, a force is applied to the top of the propeller. And since the propeller is spinning clockwise, that force is felt 90 degrees to the right. That forward-moving force, on the right side of the propeller, creates a yawing motion to the left.

The middle seats are safer than the window or aisle seats, as you might expect, because of the buffer provided by having people on either side, professor Drury said to the Conversation. He noted that sitting next to an exit row can ensure a quick exit if there is an emergency, except in case if there is a fire.

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.
