Delta Air Lines Flight 554
Delta Air Lines Flight 554 was a scheduled Delta Air Lines domestic passenger flight between Atlanta and New York City's LaGuardia Airport. On October 19, 1996, the McDonnell Douglas MD-88 aircraft struck the approach light structure and the vertical edge of the concrete landing deck during its approach to land on Runway 13 at LaGuardia Airport. The aircraft proceeded to skid 2,700 feet down the runway before coming to a rest. Of the 58 passengers and 5 crew members aboard, 5 received minor injuries. The aircraft was substantially damaged and repaired for $14 million. The final report by the National Transportation Safety Board (NTSB) found that the probable cause of the accident was the inability of the captain, because of his use of monovision contact lenses, to overcome his misperception of the aircraft's position relative to the runway during the visual portion of the approach. Background Aircraft The aircraft involved was a McDonnell Douglas MD-88, registered as N914D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 or longer approach light s ...

Serial Number
A serial number (SN) is a unique identifier used to ''uniquely'' identify an item, and is usually assigned incrementally or sequentially. Despite being called serial "numbers", they do not need to be strictly numerical and may contain letters and other typographical symbols, or may consist entirely of a character (computing), character string (computer science), string. Applications of serial numbering Serial numbers identify otherwise identical individual units, thereby serving various practical uses. Serial numbers are a deterrent against theft and counterfeit products, as they can be recorded, and stolen or otherwise irregular goods can be identified. Banknotes and other transferable documents of value bear serial numbers to assist in preventing counterfeiting and tracing stolen ones. They are valuable in quality control, as once a defect is found in the production of a particular batch of product, the serial number will identify which units are affected. Some items with ...

McDonnell Douglas DC-9
The McDonnell Douglas DC-9 is an American five-abreast, single-aisle aircraft designed by the Douglas Aircraft Company. It was initially produced as the Douglas DC-9 prior to August 1967, after which point the company had merged with McDonnell Aircraft to become McDonnell Douglas. Following the introduction of its first jetliner, the high-capacity DC-8, in 1959, Douglas was interested in producing an aircraft suited to smaller routes. As early as 1958, design studies were conducted; approval for the DC-9, a smaller all-new jetliner, came on April 8, 1963. The DC-9-10 first flew on February 25, 1965, and gained its type certificate on November 23, to enter service with Delta Air Lines on December 8. The DC-9 is powered by two rear-mounted Pratt & Whitney JT8D low-bypass turbofan engines under a T-tail for a cleaner wing aerodynamic. It has a two-person flight deck and built-in airstairs to better suit smaller airports. The aircraft was capable of taking off from 5,000 ft r ...

First Officer (aviation)
In aviation, the first officer (FO), also called co-pilot, is a Aircraft pilot, pilot in addition to the Pilot in command, captain, who is the legal commander. In the event of incapacitation of the captain, the first officer will assume command of the aircraft. Requirement Historically, large aircraft had several personnel on the flight deck, such as a Air navigator, navigator, a flight engineer, and a dedicated radio operator. Improvements in automation and reliability have reduced this to two. Many aircraft require a minimum of two flight crew. The minimum crew requirement will be stated in the aircraft manuals by the manufacturer. In the European Union, all turbo-propeller aeroplanes with a maximum approved passenger seating configuration of more than nine and all turbo-jet aeroplanes require two pilots.EU OPS (965) Subpart N, Ops 1.940 Composition of flight crew Role Control of the aircraft is normally shared equally between the first officer and the captain, with one pilot ...

North American F-100 Super Sabre
The North American F-100 Super Sabre is an American supersonic jet fighter aircraft designed and produced by the aircraft manufacturer North American Aviation. The first of the Century Series of American jet fighters, it was the first United States Air Force (USAF) fighter capable of supersonic speed in level flight. The F-100 was envisioned during the late 1940s as a higher-performance successor to the F-86 Sabre air superiority fighter. Initially referred to as the ''Sabre 45'', it was delivered as an unsolicited proposal to the USAF in January 1951, leading to two prototypes being ordered one year later following modifications. The first ''YF-100A'' performed its maiden flight on 25 May 1953, seven months ahead of schedule. Flight testing demonstrated both the F-100's promising performance and several deficiencies, which included its tendency of yaw instability and inertia coupling that led to numerous fatal accidents. On 27 September 1954, the F-100A officially entere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Airline Transport Pilot Licence
The airline transport pilot license (ATPL), or in the United States of America, an airline transport pilot (ATP) certificate, is the highest level of aircraft pilot certificate. In the United States, those certified as airline transport pilots (unconditional) are authorized to act as pilot in command on scheduled air carriers' aircraft under CFR 14 Part 121. In EASA states and the United Kingdom, pilots must hold an ATPL before they can be pilot in command of a multi-pilot aircraft flown for commercial air transport operations. Context and privileges Any pilot operating an aircraft for money must start by obtaining a commercial pilot license (CPL). This permits the pilot to carry out aerial work, such as crop spraying or banner towing. However, in commercial air transport (CAT) operations, a CPL holder may only act as pilot in command of single-pilot aircraft or as co-pilot of multi-pilot aircraft. Commercial air transport is defined as "the transport of passengers, car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
