	Airplane flight mechanics (Site not responding. Last check: 2007-10-17)
		Yaw is induced by a moveable rudder, attached to a vertical fin usually at the rear of the airplane.
		It was determined that as an airplane approaches the speed of sound, the air approaching the airplane is compressed and shock waves are produced in a conical shape as the airplane meets and exceeds the sound barrier.
		Airplane that need control at extreme angles of attack are sometimes fitted with a canard configuration, in which pitching movement is created using a forward foreplane (roughly level with the cockpit).

	Fixed-wing aircraft - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-10-17)
		There are also rare examples of aircraft which can vary the angle of incidence of their wings in flight, such the F-8 Crusader, which are also considered to be "fixed-wing".
		Sir George Cayley, the inventor of the science of aerodynamics, was building and flying models of fixed wing aircraft as early as 1803, and he built a successful passenger-carrying glider in 1853, but it is known the first practical self-powered aeroplanes were designed and constructed by Clément Ader.
		The Wright Brothers made their first successful test flights in December 17, 1903 and by 1904 the Flyer III was capable of fully-controllable stable flight for substantial periods.

	The Role of Human Factors in Improving Aviation Safety - Text Only
		Flight crew errors typically occur when the crew does not perceive a problem and fails to correct the error in time to prevent the situation from deteriorating.
		For example, when a mechanic needs to turn a valve from an awkward position, it is important that the force required to turn the valve must be within the mechanic's capability in that posture.
		Flight and maintenance crews are often unduly exposed to blame because they are the last line of defense when unsafe conditions arise.

	Airplane Flight
		Airplanes are held up by the way air pressure rearranges itself when air flows over the wing of an airplane.
		With the airplane in flight, an air flow passes over the wing, and the shape of the wing's cross section--curved above, flat or nearly flat below--reduces the pressure on top, causing the extra pressure from below to exert a lifting force ("lift").
		Faster airplanes, however, need propellers with adjustable blades, able to increase the angle ("pitch") at which they "bite" into the air as the flight speed increases, so that they always face into the combined velocity v due to their own motion and that of the airplane.

	Bienvenidos al Club Radio Control Libélula -- links
		This is somewhat similar to the radio you may have in your family automobile, except the radio in the airplane perceives commands from the transmitter, while the radio in your car perceives music from the radio station.
		A landing gear strut is the portion that holds the wheel assembly to the airplane, and away from the wing or fuselage.
		This is found on the type of airplane that has the two large wheels in the front, and the small one in the rear.

	Mechanics of Flight (Site not responding. Last check: 2007-10-17)
		The mechanical features of an airplane affect its direction and orientation during flight.
		The pitch is the movement of the airplane in the lateral axis.
		Airplanes differ from other modes of transportation because the faster the plane is moving the more effective the control surfaces will be due to the increased airflow.

	The mechanics of flight (Site not responding. Last check: 2007-10-17)
		As we celebrate the airplane as one of the great engineering achievements of the 20th century, it is useful to examine, and appreciate, some of those contributions.
		Where over-water flight was once the province of the foolhardy, we now routinely trust hundreds of lives to only two of these modern engines on intercontinental flights thousands of miles long.
		Perhaps the most clearly mechanical flight of all is that of helicopters, for here is a machine that depends on active mechanisms to create lift as well as control the flight.

	Lesson 22b--Airplane Flight
		If on the other hand we prefer to use the airplane as our frame of reference, then the air is what moves, blowing in the opposite direction to the flight and flowing around the wings and the aircraft.
		Another force on the wing and on the airplanes is the drag--that is the name given to the air resistance, and it also grows like the square of the velocity.
		The faster the airplane flies, the smaller is the part that pulls and the greater the part that resists and must be overcome.

	Flight dynamics - Wikipedia, the free encyclopedia
		Flight dynamics is the study of orientation of air and space vehicles and how to control the critical flight parameters, typically named pitch, roll and yaw.
		Yaw is rotation about the normal axis—an axis perpendicular to the pitch and roll axes.
		If an airplane model placed on a flat surface is spun or pivoted around the center of mass (coordinate origin) it would be described as yawing.

	Airplane Flight: How High? How Fast?
		That was done for the U-2, a light-weight airplane with a very long and efficient wing, but such a design would not work on the scale of an airliner.
		The take-off weight of "Voyager" was 9700 pounds, and to lift such a heavy airplane, it used two engines--one pushing and one pulling--to reach the required airspeed of 138 mph.
		As a result the second half of the flight was much slower than the first, and much harder on the sleep-deprived pilots.

		Joachim Grenestedt, associate professor of mechanical engineering and mechanics, designed "canted tabs" that are attached to the ailerons, the movable control surfaces on the wings that are used to roll an aircraft upright.
		Three tabs were mounted on each aileron for the test flights, which took place at the National Test Pilot School (NTPS) in Mojave, Calif. The tabs used in these tests could be adjusted in flight by as much as 30 degrees.
		Stability is the tendency of an airplane to fly straight, level and in an upright position.

	The Bird Site: Flight
		As with an airplane, four main forces affect the flight of a bird: lift, drag, thrust, and the downward pull of gravity.
		Birds with different types of flight have wings that are shaped very differently.
		Rather than rowing a bird through the air, the wings act like the propeller on an airplane to pull the bird forward.

		The form is a piece of paper that the pilot completes and then the mechanics read and correct the problem.
		They then respond in writing on the lower half of the form what remedial action was taken and the pilot reviews the gripe sheets before the next flight.
