The landing gear of an aircraft that uses tandem wheels mounted along the center line of the aircraft fuselage.
Some aircraft having bogie landing gear are supported while parked by outrigger wheels mounted far out on the wing.

The large amount of current that flows into an electrical machine when the switch is first closed. When an electric motor is connected to a power source, a high rate of current begins to flow. This inrush current causes the rotor to begin to turn, and as it turns, it produces a back voltage, or counter EMF, that opposes the source voltage. Since the CEMF opposes the source voltage, the net voltage (the voltage that actually forces the current through the motor) drops, and the current flowing into the motor decreases to a value much lower than the inrush current.
Incandescent light bulbs also cause a high inrush current. The resistance of the light bulb filaments is low when they are cold, but as soon as current flows through them, they get hot, and their resistance increases. The current drops below that of the inrush current as the filament resistance increases.

The large gear in a planetary gear system. The bell gear may be either stationary or driven, and it surrounds, and meshes with, the planetary gears as they rotate around the sun gear.

The last fix for an arriving aircraft. Normally, it is the outer marker of the runway in use. However, it may be the actual threshold or other suitable common point on the approach path for the particular runway configuration.
Industry:Aviation
The last flight maneuver made by an airplane in a successful landing. The airplane is slowed down in preparation for landing, and it descends along a gradually sloping flight path that brings it to the end of the runway. When the airplane is over the end of the runway, just a few feet above the surface, the pilot flares by gently pulling back on the control wheel.
Flaring increases the angle of attack and allows the airplane to settle onto the runway with the slowest forward speed and the least vertical speed. Flaring is sometimes called rounding out.
Industry:Aviation
The lateral axis of an aircraft that extends from wing tip to wing tip and passes through the center of gravity. This is the axis about which the aircraft pitches.
Industry:Aviation
The lateral spacing of aircraft at the same altitude by requiring operation on different routes or in different geographic locations.
Industry:Aviation
The lateral, or pitch, axis of an aircraft. The vertical, or yaw, axis is the Z-axis, and the longitudinal, or roll, axis is the X-axis.
Industry:Aviation
The law of conservation of energy states that energy can neither be created nor destroyed, but it can be changed from one form into another.
