Pilots can raise the spoilers to decelerate the airplane as it approaches the runway. And even while on the runway, pilots will typically leave the wing spoilers raised. Raised wing spoilers create drag, which essentially slows down the airplane so that it's able to brake more quickly.

The first indication to passengers that a plane is descending is the reduction in engine power, but that might not mean the aircraft is slowing. The most comfortable and quiet way for pilots to reduce the speed of a plane during the stages of descent is to level off briefly.
When landing, however, pilots may use the reverse thrust feature. Reverse thrust changes the direction of the engines' thrust. Rather than projecting out the rear, the thrust will be projected out the front. This reversal of thrust provides deceleration that allows airplanes to slow down more quickly when landing.
So that leaves the final descent and landing. They take up about 4% of the average flight, lasting twice as long as takeoff and initial climb. But a whopping 49% of fatal accidents occur in this short window, making the final descent and landing the deadliest part of an average flight.
As per the officials, there is a commercial plane crash every 16.7 million flights. It means for every 1,000,000 flights, 0.06 planes crash. The aviation authorities have implemented strict safety protocols which have reduced plane crashes by roughly 5.3 % per year over the past 20 years.
Transferring too much weight onto the nosewheel causes a situation called wheelbarrowing, which can lead to a loss of directional control, prop strike, or nose gear collapse. On top of those problems, with little to no weight on your main landing gear, you have little braking action.
If the plane doesn't crash, the descent rate generally can't hurt you. If the plane crashes, the horizontal deceleration is likely to do far more harm than the vertical deceleration. That said, 18,000 feet per minute is pretty fast, like 180 knots, so unpressurized it could cause possibly ear & sinus damage.
When an aircraft experiences turbulence, the plane can drop or change altitude suddenly. This is why pilots always caution passengers to buckle up and stay seated when they are experiencing flight turbulence. The sudden movements put passengers at risk.
Gravity and drag (air resistance, which is friction caused by air rubbing against the plane) try to pull the plane down and slow its speed. A plane must be built so that lift and thrust are stronger than the pull of gravity and drag by just the right amount. Lift from the wings is used to overcome the force of gravity.
In modern aircraft with modern avionics, the descent profile is automatically calculated by the computers. When prevailing winds are entered the flight management system can accurately determine the top of descent and the rate of descent that is required.
Wake turbulence can cause a plane to vibrateThe bigger the plane, the greater the wake. Like crosswinds, pockets of unstable air can force the pilot to react to keep the plane stable. These sudden movements cause the plane's wings to flex again, creating vibrations throughout the aircraft.
Airplanes can't reverse direction in midair. Rather, reverse thrust is used primarily to assist pilots in decelerating their airplane prior to landing. When engaged, it changes the direction in which air comes out of the airplane's engines, allowing the airplane to slow down in preparation of landing.
It's called a ground loop. When a plane lands the pilot has to quickly do two things to keep the plane going straight: get ALL the wheels tight on the ground, and use the rudder and to steer the plane straight. If there is a strong crosswind, it can be quite tricky to do this in a small plane.
Definition. A Hard Landing, in some regions referred to as a heavy landing, is a landing in which the manufacturer's touchdown limitation, expressed either as a rate of descent or as a 'g' loading value, has been exceeded.
If wind weakens right when the plane is about to land, passengers may feel a bump during touchdown. This does not require a reckless drop. Sudden changes in wind conditions can still be felt when descending from the altitude of 1–3 metres,” says Siivola.
In the middle, at the backNonetheless, a TIME investigation that looked at 35 years of aircraft accident data found the middle rear seats of an aircraft had the lowest fatality rate: 28%, compared with 44% for the middle aisle seats.
