Lauda Air Flight 004
Lauda Air Flight 004 (NG004/LDA004) was a regularly scheduled international passenger flight from Hong Kong, via Bangkok, Thailand, to Vienna, Austria. On 26 May 1991, the Boeing 767#767-300ER, Boeing 767-300ER operating the route crashed following an uncommanded deployment of the Thrust reversal, thrust reverser on the Aircraft engine#Engine position numbering, No. 1 engine during the climb phase, causing the aircraft to enter an Stall (fluid dynamics), aerodynamic stall, uncontrolled dive, and in-flight breakup, killing all 213 passengers and ten crew members on board. It is the deadliest aviation accident involving the Boeing 767, and the deadliest aviation accident in Thailand's history as of 2025. The accident marked the 767's first fatal incident and third hull loss.. Formula One world motor racing champion Niki Lauda, who founded and ran Lauda Air, was personally involved in the accident investigation. Aircraft The aircraft involved was a Boeing 767-300ER, the 283rd Boeing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loss Of Control (aeronautics)
In aeronautics, loss of control (LOC) is the unintended departure of an aircraft from controlled flight and is a significant factor in several Aviation accidents and incidents, aviation accidents worldwide. In 2015 it was the leading cause of general aviation accidents. Loss of control may be the result of mechanical failure, external disturbances, aircraft upset conditions, or inappropriate crew actions or responses. Causes Loss of control causes aircraft to depart from normal flight and possibly reach altitudes or encounter situations from which it can be difficult or impossible to recover, such as a Stall (fluid dynamics), stall or a Spin (aerodynamics), spin. Due to the certification and design processes, it is extremely rare for aircraft to experience a loss of control without extreme mishandling or a technical defect. A NASA study focused on identifying causal factors and addressing mitigation challenges related to aircraft loss of control had developed a preliminary list o ...

Stall (fluid Dynamics)
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack exceeds its critical value.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 486. Aviation Supplies & Academics, 1997. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil – including its shape, size, and finish – and Reynolds number. Stalls in fixed-wing aircraft are often experienced as a sudden reduction in lift. It may be caused either by the pilot increasing the wing's angle of attack or by a decrease in the critical angle of attack. The former may be due to slowing down (below stall speed), the latter by accretion of ice on the wings (especially if the ice is rough). A stall does not mean that the engine(s) have stopped working, or that the aircraft has stopped moving—the effect is the same even in an unpowered glider aircraft. Vectored thrust in aircraft is used to maintain al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uthai Thani Province
Uthai Thani (, ), one of Thailand's seventy-six provinces (''changwat'') lies in lower northern Thailand. Neighbouring provinces are (from north clockwise) Nakhon Sawan, Chai Nat, Suphan Buri, Kanchanaburi and Tak. It lies somewhat off the route between Bangkok, 200 km distant and Chiang Mai. Geography The province stretches from the upper plains of the Chao Phraya River valley, to forested mountains in the west. The Sakae Krang River, a tributary of the Chao Phraya River, is the main watercourse of in the province. The total forest area is or 51.4 percent of provincial area. The Huai Kha Khaeng wildlife sanctuary, at the western boundary bordering Tak province, was declared a World Heritage Site in 1991. It is home to most of the forest animals of Southeast Asia, including tigers and elephants. Huai Kha Kaeng wildlife sanctuary, along with one other wildlife sanctuary, make up region 12 (Nakhon Sawan) of Thailand's protected areas. * Huai Kha Khaeng Wildlife San ...

Quick Reference Handbook
A Quick Reference Handbook (QRH) is a quick-access manual for aircraft pilots that contains all the procedures applicable for non-normal and emergency conditions in an easy-to-use format. Performance data corrections are also provided for specific conditions. A QRH is kept in the cockpit and can be consulted whenever the flight crew experiences in-flight problems. Format The first QRHs in the 20th century were made out of paper, but in the 21st century, many pilots have switched to so-called electronic flight bags (EFB), which have the advantage of electronic search functions, but require electricity to work. Some modern aircraft such as the Airbus A350, and Airbus A380, have computerised some of the checklists with their own integrated EFB. However, pilots still are required to have their own EFB as an added redundency as not all procedures and use cases will display the correct checklists, due to some problems being unable to be correctly identified or diagnosed by the onboa ...

Engine-indicating And Crew-alerting System
An engine-indicating and crew-alerting system (EICAS) is an integrated system used in modern aircraft to provide aircraft flight crew with instrumentation and crew annunciations for aircraft engines and other systems. On EICAS equipped aircraft the "recommended remedial action" is called a checklist. Components EICAS typically includes instrumentation of various engine parameters, including for example speed of rotation, temperature values including exhaust gas temperature, fuel flow and quantity, oil pressure etc. Other aircraft systems typically monitored by EICAS are for example hydraulic, pneumatic, electrical, deicing, environmental and control surface systems. EICAS has high connectivity & provides data acquisition and routing. Limitations On some Bombardier aircraft, it is possible to call up the wrong checklist. Messages forbidding take-off can be shown as advisories. Gallery File:United 787 cockpit panel KSEA AVGeek (18760994951).jpg, EICAS of a Boeing 787 ...

Time In Thailand
Thailand follows UTC+07:00, which is 7 hours ahead of UTC. The local mean time in Bangkok was originally UTC+06:42:04. Thailand used this local mean time until 1920, when it changed to Indochina Time, UTC+07:00; ICT is used all year round as Thailand never observed daylight saving time. Thailand shares the same time zone with Vietnam, Cambodia, Laos, Christmas Island, and Western Indonesia, as well as parts of Russia. History * Prior to 1 January 1901, locations in Siam with an astronomical observatory would adopt local mean time based on the observatory's geographic position. Chiang Mai Province and two other provinces each had an observatory, hence, each province had its own distinct local mean time, with minutes of difference between the three locations. * On 1 April 1920, the mean time of the 105th meridian east (passing through Ubon Ratchathani Province) was adopted by Siam as the new standard time. The mean time of the 105th meridian is 7 hours ahead of Green ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Dispatch (Lexington)
''The Dispatch'' is an American, English language daily newspaper published in Lexington, North Carolina. The newspaper is published Tuesday through Saturday with no Sunday or Monday editions. History ''The Dispatch'' began publication in 1902, succeeding the weekly ''Davidson Dispatch'' (1882–1902), founded by T.B. Eldridge. The paper increased to semi-weekly publication in 1919 and to a six-day-a-week schedule on September 6, 1948.

Hull Loss
A hull loss is an aviation accident that damages the aircraft beyond economic repair, resulting in a total loss. The term also applies to situations where the aircraft is missing, the search for its wreckage is terminated, or the wreckage is logistically inaccessible. The aviation industry uses the metric of "hull losses per 100,000 flight departures" to measure the relative risk of a given flight or aircraft. There is no official ICAO or NTSB definition. From 1959 to 2006, 384 of 835 hull losses were non-fatal. Constructive hull loss takes into account other incidental expenses beyond repair, such as salvage, logistical costs of repairing non- airworthy aircraft within the confines of the incident site, and recertifying the aircraft. Airlines typically have insurance to cover hull loss. Their policies—like many covering assets that are subject to depreciation—typically pay the insured a formulaic used-item value. A damaged aircraft will often simply be scrapped. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
