It's called 'flaring to a landing,' where the nose of the aircraft is brought up, raising angle of attack, lowering airspeed, until the main gear gently touch down on the runway. When speaking exclusively of that portion of the landing path, an aircraft is said to be 'flaring' or 'in the flair.'

What is the purpose of retracting landing gear's pivot?
When the landing gear retracts, it is very important for aerodynamics that they retract into the body of the aircraft as much as possible. However, placement of the landing gear depends ultimately on factors such as the aircraft's center of gravity, its weight, its possible fuel load and much more, there may not be a good locaction in the aircraft for the wheels to rectract fully without some kind of articulation. As a result, aircraft designers often must come up with some pretty interesting solutions to enable to landing gear to be retracted fully into a space that is otherwise unused in the aircraft. Often in order for the landing gear to retract into its well, the wheel trucks may have to be rotated or pivoted. Large aircraft in particular often have multiple wheels for each of the landing gear. It is particularly difficult to design a retraction system for these as the wheel trucks may be very large and ungainly. Some large aircraft have the ability to pivot the landing gear to one direction or another for landing. This is done to increase the aircraft's capacity to land in cross-winds. In a strong cross-wind the aircraft may not be able to land gracefully pointed straight down the runway, and so the landing gear may be off-set one direction or another to allow the aircraft to land with a slight crab-angle.
Does a glider have landing gear?
Yes, most gliders do have landing gear. A common arrangement is a single wheel in the fuselage just forward of the center of weight, with a tiny tail wheel and roller skate wheels at the tips of the wings. The center wheel is mostly enclosed by the fuselage, making the aircraft appear from a distance that it does not have landing gear.
Why an airplane lands on his behind wheels?
Most airplanes today have a set of landing gear under their wings and one under the nose. Earlier planes had wheels under the wings and a rear wheel on the very tail. So, I'm not sure what your question relates to. But aircraft are designed to land on their main landing gear. These are built stronger to take the impact loads of landing and stopping the aircraft descent. Also, the airplane is usually approaching at a slight Nose Up angle, so it would seem natural to have the gear at the center of the airplane or a little aft as that will be the first part to touch the ground. Finally, the gear is designed to hold the weight of the aircraft. The center of gravity of the aircraft is at the front part of the wing or at the center of where the wing attaches to the fuselage. The landing gear needs to be close or exactly on the center of gravity of the airplane. As stated above, these are usually the rear wheels.
Who will direct a plane at take off and landing?
At a large airport that handles commercial aircraft, the first controller that the pilot contacts is the ground controller. That controller is stationed in the control tower and directs the movement of the aircraft from the gate to the end of the runway. The pilot then contacts the local controller who directs traffic on the runways and in the local vicinity of the airport. The local controller is also in the control tower and clears the aircraft for takeoff. After the aircraft is airborne, the pilot contacts the departure controller who locates the aircraft on RADAR and directs the aircraft out of the terminal area. At that point, the pilot contacts the Air Route Traffic Control Center. Center then locates the aircraft on RADAR and directs it to the terminal area of the airport at which the aircraft will land. Center "hands off" the aircraft to the approach controller who locates the aircraft on RADAR and guides it to the final approach course of the runway that will be used for the landing. When the aircraft is on final approach, the approach controller will hand the aircraft off to the local controller who clears the aircraft to land. When the aircraft has landed and has taxied clear of the runway, the pilot contacts the ground controller who directs the aircraft to the gate.
What is runway threshold light?
these are the lights that are placed in the areas where the aircraft first touches the runway. the runway threshold ligts should be placed perpendicular to runway center line and as close as possible.The lights should show visible green in the direction of aircraft.
The direction away from the center of the earth is?
any direction. you can go any direction to get out of the center of the earth, but the center is to hot for humans, so dont try it
Where are most of the aerodynamic forces generated on an airplane?
Four Forces on an AirplaneA force may be thought of as a push or pull in a specific direction. A force is a vector quantity so a force has both a magnitude and a direction. When describing forces, we have to specify both the magnitude and the direction. This slide shows the forces that act on an airplane in flight.WeightWeight is a force that is always directed toward the center of the earth. The magnitude of the weight depends on the mass of all the airplane parts, plus the amount of fuel, plus any payload on board (people, baggage, freight, etc.). The weight is distributed throughout the airplane. But we can often think of it as collected and acting through a single point called the center of gravity. In flight, the airplane rotates about the center of gravity.Flying encompasses two major problems; overcoming the weight of an object by some opposing force, and controlling the object in flight. Both of these problems are related to the object's weight and the location of the center of gravity. During a flight, an airplane's weight constantly changes as the aircraft consumes fuel. The distribution of the weight and the center of gravity also changes. So the pilot must constantly adjust the controls to keep the airplane balanced, or trimmed.LiftTo overcome the weight force, airplanes generate an opposing force called lift. Lift is generated by the motion of the airplane through the air and is an aerodynamic force. "Aero" stands for the air, and "dynamic" denotes motion. Lift is directed perpendicular to the flight direction. The magnitude of the lift depends on several factors including the shape, size, and velocity of the aircraft. As with weight, each part of the aircraft contributes to the aircraft lift force. Most of the lift is generated by the wings. Aircraft lift acts through a single point called the center of pressure. The center of pressure is defined just like the center of gravity, but using the pressure distribution around the body instead of the weight distribution.The distribution of lift around the aircraft is important for solving the control problem. Aerodynamic surfaces are used to control the aircraft in roll, pitch, and yaw.DragAs the airplane moves through the air, there is another aerodynamic force present. The air resists the motion of the aircraft and the resistance force is called drag. Drag is directed along and opposed to the flight direction. Like lift, there are many factors that affect the magnitude of the drag force including the shape of the aircraft, the "stickiness" of the air, and the velocity of the aircraft. Like lift, we collect all of the individual components' drags and combine them into a single aircraft drag magnitude. And like lift, drag acts through the aircraft center of pressure.ThrustTo overcome drag, airplanes use a propulsion system to generate a force called thrust. The direction of the thrust force depends on how the engines are attached to the aircraft. In the figure shown above, two turbine engines are located under the wings, parallel to the body, with thrust acting along the body centerline. On some aircraft, such as the Harrier, the thrust direction can be varied to help the airplane take off in a very short distance. The magnitude of the thrust depends on many factors associated with the propulsion system including the type of engine, the number of engines, and the throttle setting.For jet engines, it is often confusing to remember that aircraft thrust is a reaction to the hot gas rushing out of the nozzle. The hot gas goes out the back, but the thrust pushes towards the front. Action reaction is explained by Newton's Third Law of Motion.The motion of the airplane through the air depends on the relative strength and direction of the forces shown above. If the forces are balanced, the aircraft cruises at constant velocity. If the forces are unbalanced, the aircraft accelerates in the direction of the largest force.
Does the aircraft resource center have schedules of air shows?
The aircraft resource center is an online magazine devoted to the art of model aircraft, and as such, they do have a schedule for model air shows in many different areas.
