Pan Am Flight 845
Pan Am Flight 845 was a Boeing 747-121, registration N747PA, operating as a scheduled international passenger flight between Los Angeles and Tokyo, with an intermediate stop at San Francisco International Airport (ICAO: KSFO). On July 30, 1971, at 15:29 PDT, while it was taking off from San Francisco bound for Tokyo, the aircraft struck approach lighting system structures located past the end of the runway, which seriously injured two passengers and caused significant damage. The crew continued the takeoff, flew out over the ocean and circling while it dumped fuel, and eventually returned for a landing in San Francisco. After coming to a stop, the crew ordered an emergency evacuation during which 27 passengers were injured exiting the aircraft, and 8 of them suffered serious back injuries. The accident was investigated by the NTSB, which determined the probable cause was the pilot's use of incorrect takeoff reference speeds. The NTSB also found various procedural failures ...

Approach Lighting System
An approach lighting system (ALS) is a lighting system installed on the approach end of an airport runway and consisting of a series of lightbars, strobe lights, or a combination of the two that extends outward from the runway end. ALS usually serves a runway that has an instrument approach procedure (IAP) associated with it and allows the pilot to visually identify the runway environment and align the aircraft with the runway upon arriving at a prescribed point on an approach. Modern approach lighting systems are highly complex in their design and significantly enhance the safety of aircraft operations, particularly in conditions of reduced visibility. Operation The required minimum visibilities for instrument approaches is influenced by the presence and type of approach lighting system. In the U.S., a CAT I Instrument landing system, ILS approach without approach lights will have a minimum required visibility of 3/4 mile, or 4000 foot runway visual range. With a 1400-foot o ...

Empennage
The empennage ( or ), also known as the tail or tail assembly, is a structure at the rear of an aircraft that provides stability during flight, in a way similar to the feathers on an arrow.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 194. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', p. 10 (27th revised edition) The term derives from the French language verb ''empenner'' which means " to feather an arrow". Most aircraft feature an empennage incorporating vertical and horizontal stabilising surfaces which stabilise the flight dynamics of yaw and pitch, as well as housing control surfaces. In spite of effective control surfaces, many early aircraft that lacked a stabilising empennage were virtually unflyable. Even so-called "tailless aircraft" usually have a tail fin (usually a vertical stabiliser). Heavier-than-air aircraft without any kind of empennage (such as the Northrop B-2) are rare, and generally use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angle Iron
Structural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section. Structural steel shapes, sizes, chemical composition, mechanical properties such as strengths, storage practices, etc., are regulated by standards in most industrialized countries. Most structural steel shapes, such as -beams, have high second moments of area, which means they are very stiff in respect to their cross-sectional area and thus can support a high load without excessive sagging. Common structural shapes The shapes available are described in many published standards worldwide, and a number of specialist and proprietary cross sections are also available. * -beam (-shaped cross-section – in Britain these include Universal Beams (UB) and Universal Columns (UC); in Europe it includes the IPE, HE, HL, HD and other sections; in the US it includes Wide F ...

Flight Dispatcher
A flight dispatcher (also known as an airline dispatcher or flight operations officer) assists in planning flight paths, taking into account aircraft performance and loading, enroute winds, thunderstorm and turbulence forecasts, airspace restrictions, and airport conditions. Dispatchers also provide a flight following service and advise pilots if conditions change. They usually work in the operations center of the airline. In the United States and Canada, the flight dispatcher shares legal responsibility with the commander of the aircraft (joint responsibility dispatch system). Operational control Dispatchers usually share responsibility for the exercise of operational control, which gives them authority to divert, delay or cancel a flight. Legal requirements known as "Federal Aviation Regulations, 14 CFR part 121" govern dispatch release in the United States. After the release of a flight (in a joint responsibility environment) the dispatcher uses sophisticated software tools to ...

Pushback
In aviation, pushback is an airport procedure during which an aircraft is pushed backwards away from its parking position, usually at an airport gate by external power. Pushbacks are carried out by special, low-profile vehicles called ''pushback tractors'' or ''tugs''. Although many aircraft are capable of moving themselves backwards on the ground using reverse thrust (a procedure referred to as a ''powerback),'' the resulting jet blast or prop wash would cause increased noise, damage to the terminal building or equipment, and hurt airport staff due to high-speed debris. This debris would also be sucked into the engine, as it is in normal use, and cause excessive wear - a major cause of wear on aircraft engines is during ground use. A pushback is therefore the preferred method when ground-handling aircraft. Definition IATA defines aircraft pushback as "rearward moving of an aircraft from a parking position to a taxi position by use of specialized ground support equipment." Proc ...
