Quick Reference Handbook
A Quick Reference Handbook (QRH) is an aircraft technical document – quick-access manual for aircraft pilots that contains all the procedures applicable for non-normal and emergency conditions in an easy-to-use format. In addition, 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, which have the advantage of electronic search functions, but require electricity to work. Some modern aircraft such as the Airbus A330 have computerised some of the checklists, but other checklists cannot be properly programmed, because some problems cannot be correctly identified or diagnosed by aircraft computers; thus, the Quick Reference Handbook remains an essential in-flight tool for the crew.

Technical Documentation
Technical documentation is a generic term for the classes of information created to describe (in technical language) the use, functionality or architecture of a product, system or service. Classes of technical documentation Classes of technical documentation may include: * patents * specifications of item or of components/materials * data sheets of item or of components/materials * test methods * manufacturing standards * system requirements * system architecture * system design documents and data including those necessary for the system development, testing, manufacturing, operation and maintenance Standardizing technical documentation Historically, most classes of technical documentation lacked universal conformity (standards) for format, content and structure. Standards are being developed to redress this through bodies such as the International Organization for Standardization(ISO), which has published standards relating to rules for preparation of user guides, manuals, pro ...

Aviation Accidents And Incidents
An aviation accident is defined by the Convention on International Civil Aviation Annex 13 as an occurrence associated with the operation of an aircraft, which takes place from the time any person boards the aircraft with the ''intention of flight'' until all such persons have disembarked, and in which a) a person is fatally or seriously injured, b) the aircraft sustains significant damage or structural failure, or c) the aircraft goes missing or becomes completely inaccessible. Annex 13 defines an aviation incident as an occurrence, other than an accident, associated with the operation of an aircraft that affects or could affect the safety of operation. A hull loss occurs if an aircraft is damaged beyond repair, lost, or becomes completely inaccessible. The first fatal aviation accident was the crash of a Rozière balloon near Wimereux, France, on June 15, 1785, killing the balloon's inventor, Jean-François Pilâtre de Rozier, and the other occupant, Pierre Romain.

Checklists
A checklist is a type of job aid used in repetitive tasks to reduce failure by compensating for potential limits of human memory and attention. It helps to ensure consistency and completeness in carrying out a task. A basic example is the "to do list". A more advanced checklist would be a schedule, which lays out tasks to be done according to time of day or other factors. A primary task in checklist is documentation of the task and auditing against the documentation. Use of a written checklist can reduce any tendency to avoid, omit or neglect important steps in any task. Applications *aid in aviation safety to ensure that critical items are not overlooked. Example: Pre-flight checklists * Used in quality assurance of software engineering, to check process compliance, code standardization and error prevention, and others. * Often used in industry in operations procedures * In civil litigation to deal with the complexity of discovery and motions practice. An example is the open ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aviation Safety
Aviation safety is the study and practice of managing risks in aviation. This includes preventing aviation accidents and incidents through research, educating air travel personnel, passengers and the general public, as well as the design of aircraft and aviation infrastructure. The aviation industry is subject to significant regulation and oversight. Aviation security is focused on protecting air travelers, aircraft and infrastructure from intentional harm or disruption, rather than unintentional mishaps. Statistics Evolution In 1926 and 1927, there were a total of 24 fatal commercial airline crashes, a further 16 in 1928, and 51 in 1929 (killing 61 people), which remains the worst year on record at an accident rate of about 1 for every flown. Based on the current numbers flying, this would equate to 7,000 fatal incidents per year. For the ten-year period 2002 to 2011, 0.6 fatal accidents happened per one million flights globally, 0.4 per million hours flown, 22.0 fatal ...

Preflight Checklist
In aviation, a preflight checklist is a list of tasks that should be performed by pilots and aircrew prior to takeoff. Its purpose is to improve flight safety by ensuring that no important tasks are forgotten. Failure to correctly conduct a preflight check using a checklist is a major contributing factor to aircraft accidents. History According to researcher and writer Atul Gawande, the concept of a pre-flight checklist was first introduced by management and engineers at the Boeing Company following the 1935 crash of the prototype Boeing B-17 (then known as the Model 299) at Wright Field in Dayton, Ohio, killing both pilots. Investigation found that the pilots had forgotten to disengage the crucial gust locks (devices which stop control surfaces moving in the wind while parked) prior to take-off. ''Life'' magazine published the resulting lengthy and detailed B-17 checklist in its 24 August 1942 issue. Crashes attributed to checklist failures * On December 26, 1968, Pan Am Fligh ...

Electronic Flight Bag
An electronic flight bag (EFB) is an electronic information management device that helps flight crews perform flight management tasks more easily and efficiently with less paper providing the reference material often found in the pilot's carry-on flight bag, including the flight-crew operating manual, navigational charts, etc. In addition, the EFB can host purpose-built software applications to automate other functions normally conducted by hand, such as take-off performance calculations. The EFB gets its name from the traditional pilot's flight bag, which is typically a heavy (up to or over ) documents bag that pilots carry to the cockpit. An EFB is intended primarily for cockpit/ flightdeck or cabin use. For large and turbine aircraft, FAR 91.503 requires the presence of navigational charts on the airplane. If an operator's sole source of navigational chart information is contained on an EFB, the operator must demonstrate the EFB will continue to operate throughout a de ...

Aircraft Flight Manual
An aircraft flight manual (AFM) is a paper book or electronic information set containing information required to operate an aircraft of certain type or particular aircraft of that type (each AFM is tailored for a specific aircraft, though aircraft of the same type naturally have very similar AFMs). The information within an AFM is also referred to a Technical Airworthiness Data (TAWD). A typical flight manual will contain the following: operating limitations, Normal/Abnormal/Emergency operating procedures, performance data and loading information. An AFM will often include: * V speeds * Aircraft gross weight * Maximum ramp weight * Maximum takeoff weight * Manufacturer's empty weight * Operating empty weight * Centre of gravity limitations * Zero-fuel weight * Takeoff distance * Landing distance Originally, an AFM would follow whichever format and order the manufacturer felt appropriate. Eventually, the General Aviation Manufacturers Association came to an agreement to standa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Turbine Engine Failure
A turbine engine failure occurs when a turbine engine unexpectedly stops producing power due to a malfunction other than fuel exhaustion. It often applies for aircraft, but other turbine engines can fail, like ground-based turbines used in power plants or combined diesel and gas vessels and vehicles. Reliability Turbine engines in use on today's turbine-powered aircraft are very reliable. Engines operate efficiently with regularly scheduled inspections and maintenance. These units can have lives ranging in the thousands of hours of operation. However, engine malfunctions or failures occasionally occur that require an engine to be shut down in flight. Since multi-engine airplanes are designed to fly with one engine inoperative and flight crews are trained to fly with one engine inoperative, the in-flight shutdown of an engine typically does not constitute a serious safety of flight issue. The Federal Aviation Administration (FAA) was quoted as stating turbine engines have a f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
