Emergency Airworthiness Directive
An emergency Airworthiness Directive (EAD) is an airworthiness directive issued when an unsafe condition exists that requires immediate action by an aircraft owner or operator. EADs are published by a responsible authorities such as FOCA, EASA or FAA related to airworthiness and maintenance of aircraft and aircraft parts. It contains measures which must be accomplished and the related periods to preserve their airworthiness. Technical information is addressed to operators and maintenance organisations of affected aircraft only. EADs become effective upon receipt of notification. Notable incidents that have led to emergency airworthiness directives * On May 25, 1979, American Airlines Flight 191, a McDonnell Douglas DC-10 crashed after takeoff from Chicago O'Hare Airport. An engine separated from the plane, damaging electrical and hydraulic systems, causing the left wing's slats to retract and stall that wing. This led to the type being grounded in June 1979. *On August 20, 2007, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airworthiness Directive
An Airworthiness Directive (commonly abbreviated as AD) is a notification to owners and operators of certified aircraft that a known safety deficiency with a particular model of aircraft, engine, avionics or other system exists and must be corrected. If a certified aircraft has outstanding airworthiness directives that have not been complied with, the aircraft is not considered airworthy. Thus, it is mandatory for an aircraft operator to comply with an AD. Purpose ADs usually result from service difficulty reporting by operators or from the results of aircraft accident investigations. They are issued either by the national civil aviation authority of the country of aircraft manufacture or of aircraft registration. When ADs are issued by the country of registration they are almost always coordinated with the civil aviation authority of the country of manufacture to ensure that conflicting ADs are not issued. In detail, the purpose of an AD is to notify aircraft owners: * that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitch (aviation)
An aircraft in flight is free to rotate in three dimensions: '' yaw'', nose left or right about an axis running up and down; ''pitch'', nose up or down about an axis running from wing to wing; and ''roll'', rotation about an axis running from nose to tail. The axes are alternatively designated as ''vertical'', ''lateral'' (or ''transverse''), and ''longitudinal'' respectively. These axes move with the vehicle and rotate relative to the Earth along with the craft. These definitions were analogously applied to spacecraft when the first manned spacecraft were designed in the late 1950s. These rotations are produced by torques (or moments) about the principal axes. On an aircraft, these are intentionally produced by means of moving control surfaces, which vary the distribution of the net aerodynamic force about the vehicle's center of gravity. Elevators (moving flaps on the horizontal tail) produce pitch, a rudder on the vertical tail produces yaw, and ailerons (flaps on the wing ...

Aviation Licenses And Certifications
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. Etymology The word ''aviation'' was coined by the French writer and former naval officer Gabriel La Landelle in 1863. He derived the term from the v ...

Angle Of Attack
In fluid dynamics, angle of attack (AOA, α, or \alpha) is the angle between a reference line on a body (often the chord line of an airfoil) and the vector representing the relative motion between the body and the fluid through which it is moving. Angle of attack is the angle between the body's reference line and the oncoming flow. This article focuses on the most common application, the angle of attack of a wing or airfoil moving through air. In aerodynamics, angle of attack specifies the angle between the chord line of the wing of a fixed-wing aircraft and the vector representing the relative motion between the aircraft and the atmosphere. Since a wing can have twist, a chord line of the whole wing may not be definable, so an alternate reference line is simply defined. Often, the chord line of the root of the wing is chosen as the reference line. Another choice is to use a horizontal line on the fuselage as the reference line (and also as the longitudinal axis).

KIRO-TV
KIRO-TV (channel 7) is a television station in Seattle, Washington, United States, affiliated with CBS and Telemundo. Owned by Cox Media Group, the station maintains studios on Third Avenue in the Belltown section of Downtown Seattle, and its transmitter is located in the city's Queen Anne neighborhood, adjacent to the station's original studios. KIRO-TV signed on in 1958 as the last commercial VHF television station for the Seattle metropolitan area; owing to its status as the television extension to KIRO (710 AM), the station immediately took the CBS affiliation from Tacoma-licensed KTNT-TV (now KSTW), but they were forced to share the affiliation for two years after the owners of both stations settled a lawsuit over the affiliation switch. Subsequently owned for more than three decades by the broadcasting division of the LDS Church, KIRO-TV briefly became a UPN affiliate when KSTW reaffiliated with CBS in 1995 during a nationwide affiliation shuffle, but rejoined the ne ...

Lithium-ion Battery
A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. It is the predominant battery type used in portable consumer electronics and electric vehicles. It also sees significant use for grid-scale energy storage and military and aerospace applications. Compared to other rechargeable battery technologies, Li-ion batteries have high energy densities, low self-discharge, and no memory effect (although a small memory effect reported in LFP cells has been traced to poorly made cells). Chemistry, performance, cost and safety characteristics vary across types of lithium-ion batteries. Most commercial Li-ion cells use intercalation compounds as the active materials. The anode or negative electrode is usually graphite, although silicon-carbon is also being increasingly used. Cells can be manufactured to prioritize either energy or power density. Handheld electronics mostly use lithium polymer batteries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
