Is air pressure higher or lower in a plane?

As you go up in an airplane, the atmospheric pressure becomes lower than the pressure of the air inside your ears. Your ears pop because they are trying to equalize, or match, the pressure. The same thing happens when the plane is on the way down and your ears have to adjust to a higher atmospheric pressure.

As stated in other answers, in steady flight there is no pressure difference along the length of the cabin, and only a miniscule one during lognitudinal acceleration.

What is the safest seat on an airplane? According to a TIME investigation from 2015 that examined 35 years of aircraft accident data, the middle seats at the back of the plane had the lowest fatality rate at 28%.

However, statistically speaking, a seat close to an exit in the front or rear, or a middle seat in the back third of the plane offers the lowest fatality rate. That said, flying is still the safest form of transport.

As the plane descends into ground effect, it may actually accelerate if the engines are producing enough thrust, since in ground effect the plane requires much less power to keep flying. Power from the engines will translate into speed, if not height.

There are also some practical reasons for turning off the lights. For one, it saves energy, since more power is needed during takeoff and landing. For another, it helps acclimate passengers' eyes to the dark, which can be beneficial in the event of an emergency landing.
