Pre-flight Safety Demonstration
A pre-flight safety briefing (also known as a pre-flight demonstration, in-flight safety briefing, in-flight safety demonstration, safety instructions, or simply the safety video) is a detailed explanation given before take-off to airline passengers about the safety features of the aircraft they are aboard. Aviation regulations do not state how an airline should deliver the briefing, only that ‘The operator of an aircraft shall ensure that all passengers are orally briefed before each take-off’.Civil Aviation Safety Authority. (2009). Civil Aviation Orders (CAO) 20.11. Canberra, Australia: Author. As a result, and depending on the in-flight entertainment system in the aircraft, as well as the airline's policy, airlines may deliver a pre-recorded briefing or provide a live demonstration. A live demonstration is performed by one or more flight attendants standing up in the aisles, while another flight attendant narrates over the public address system. A pre-recorded briefing may ...

Comic Relief
Comic relief is the inclusion of a humorous character, scene, or witty dialogue in an otherwise serious work, often to relieve tension. Definition Comic relief usually means a releasing of emotional or other tension resulting from a comic episode interposed in the midst of serious or tragic elements in a drama. Comic relief is often seen but is not limited to, taking the form of a bumbling, wisecracking sidekick of the hero or villain in a work of fiction. A sidekick used for comic relief will usually comment on the absurdity of the hero's situation and make comments that would be inappropriate for a character who is to be taken seriously. Other characters may use comic relief as a means to irritate others or keep themselves confident. Application Sometimes comic relief characters will appear in fiction that is comic. This generally occurs when the work enters a dramatic moment, but the character continues to be comical regardless. External comic reliefs and internal comic reli ...

Boeing 787
The Boeing 787 Dreamliner is an American wide-body jet airliner developed and manufactured by Boeing Commercial Airplanes. After dropping its unconventional Sonic Cruiser project, Boeing announced the conventional 7E7 on January 29, 2003, which focused largely on efficiency. The program was launched on April 26, 2004, with an order for 50 aircraft from All Nippon Airways (ANA), targeting a 2008 introduction. On July 8, 2007, a prototype 787 was rolled out without major operating systems, and then the aircraft experienced multiple delays until its maiden flight on December 15, 2009. Type certification was received in August 2011 and the first 787-8 was delivered in September 2011 before entering commercial service on October 26, 2011, with ANA. At launch, Boeing targeted the 787 with 20% less fuel burn than replaced aircraft like the Boeing 767, carrying 200 to 300 passengers on point-to-point routes up to , a shift from hub-and-spoke travel. The twinjet is powered by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Oxygen System
Aircraft emergency oxygen systems or air masks are emergency equipment fitted to pressurized commercial aircraft, intended for use when the cabin pressurization, cabin pressurisation system has failed and the cabin altitude has climbed above a safe level. It consists of a number of individual yellow oxygen masks stored in compartments near passenger seats and near areas like lavatories and galleys, and an oxygen source, like a centralized gaseous cylinder or decentralized chemical oxygen generator. Use Most commercial aircraft that operate at high flight altitudes are pressurized at a maximum cabin altitude of approximately 8,000 feet. On most pressurized aircraft, if cabin pressurization is lost when the aircraft is flying at an altitude above 4.267 m (14,000 feet), compartments containing the oxygen masks will open automatically, either above or in front of the passenger and crew seats, and the oxygen masks will drop down in front of the passenger. Oxygen masks may also drop on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-heeled Shoe
High-heeled shoes, also known as high heels, are a type of shoe with an angled sole. The heel in such shoes is raised above the ball of the foot. High heels cause the legs to appear longer, make the wearer appear taller, and accentuate the calf muscle. There are many types of heels in varying colors, materials, styles, and heights. High heels have been used in various ways to communicate nationality, professional affiliation, gender, and social status. High heels have been important in the West. In early 17th century Europe, for example, high heels were a sign of masculinity and high social status. It wasn't until the end of the century that this trend spread to women's fashion. By the 18th century, high-heeled shoes had split along gender lines. By this time, heels for men's shoes were chunky squares attached to riding boots or tall formal dress boots while women's high heels were narrow and pointy and often attached to slipper-like dress shoes (similar to modern heels). ...

Carry-on
The term hand luggage or cabin baggage (normally called carry-on in North America) refers to the type of luggage that passengers are allowed to carry along in the passenger compartment of a vehicle instead of a separate cargo compartment. Passengers are allowed to carry a limited number of smaller bags with them in the vehicle, which typically contain valuables and items needed during the journey. There is normally storage space provided for hand luggage, either under seating, or in overhead lockers. Trains usually have luggage racks above the seats and may also (especially in the case of trains travelling longer distances) have luggage space between the backs of seats facing opposite directions, or in extra luggage racks, for example, at the ends of the carriage (train car in American English) near the doors. Commercial air travel Hand baggage allowance is a topic frequently discussed in the context of commercial air travel. On the one hand, passengers may want to have more ...

Exit Row
An exit row is a row of seats on board a commercial airliner that is next to an emergency exit. Exit rows may be next to overwing exits or full-sized exit doors. Passenger criteria Since passengers seated in an exit row must be able and willing to assist the crew during an evacuation of the aircraft, civil aviation boards and national governments set specific requirements for passengers seated in an exit row. While exact requirements vary by country and airline, frequently exit row passengers must: *Be of a certain minimum age, ranging from 12 to 18 depending on the airline's policies and/or local law. *Not be traveling with anyone requiring special assistance in an emergency (such as an infant or person with a disability), or an animal (including service animals) *Have no physical or mental impairment that would hinder quickly reaching and operating the emergency exit. *Speak and read the national language of the airline's home country (e.g. English on Qantas or German on Lufthan ...

Evacuation Slide
An evacuation slide is an inflatable slide used to evacuate an aircraft quickly. An escape slide is required on all commercial (passenger carrying) aircraft where the door sill height is such that, in the event of an evacuation, passengers would be unable to step down from the door uninjured (Federal Aviation Administration requires slides on all aircraft doors where the floor is or more above the ground). Escape slides are packed and held within the door structure inside the ''slide bustle'', a protruding part of the inside of an aircraft door that varies with aircraft size, door size and door location. In many modern planes, to reduce evacuation time, evacuation slides deploy automatically when a door is opened in an "armed" condition. Modern planes often indicate an armed condition with an indicator light. Regulations Federal Aviation Administration and EASA regulations require an approved method of escape on all aircraft exits where the floor is or more above the ground) ...

Emergency Exit
An emergency exit in a structure is a special exit for emergencies such as a fire: the combined use of regular and special exits allows for faster evacuation, while it also provides an alternative if the route to the regular exit is blocked. The qualifications for an emergency exit are as follows: it must be in a location that is easily accessible, the exit must have an area or location that it can bring people to in the event of any emergency, it must be controlled by the inside of the building, it must be well managed and regularly up kept, and it must be in a permanent location. It is usually in a strategically located (e.g. in a stairwell, hallway, or other likely places) outward opening door with a crash bar on it and with exit signs leading to it. The name is a reference to when they were frequently used, however, a fire exit can also be a main doorway must be able to be unlocked from the inside of the room. A fire escape is a special kind of emergency exit, mounted to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbulence
In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to a laminar flow, which occurs when a fluid flows in parallel layers, with no disruption between those layers. Turbulence is commonly observed in everyday phenomena such as surf, fast flowing rivers, billowing storm clouds, or smoke from a chimney, and most fluid flows occurring in nature or created in engineering applications are turbulent. Turbulence is caused by excessive kinetic energy in parts of a fluid flow, which overcomes the damping effect of the fluid's viscosity. For this reason turbulence is commonly realized in low viscosity fluids. In general terms, in turbulent flow, unsteady vortices appear of many sizes which interact with each other, consequently drag due to friction effects increases. This increases the energy needed to pump fluid through a pipe. The onset of turbulence can be predicted by the dimensionless Rey ...

Seat Belt
A seat belt (also known as a safety belt, or spelled seatbelt) is a vehicle safety device designed to secure the driver or a passenger of a vehicle against harmful movement that may result during a collision or a sudden stop. A seat belt reduces the likelihood of death or serious injury in a traffic collision by reducing the force of secondary impacts with interior strike hazards, by keeping occupants positioned correctly for maximum effectiveness of the airbag (if equipped), and by preventing occupants being ejected from the vehicle in a crash or if the vehicle rolls over. When in motion, the driver and passengers are traveling at the same speed as the vehicle. If the vehicle suddenly stops or crashes, the occupants continue at the same speed the vehicle was going before it stopped. A seatbelt applies an opposing force to the driver and passengers to prevent them from falling out or making contact with the interior of the car (especially preventing contact with, or going t ...

Brace Position
To assume a brace position or crash position is an instruction that can be given to prepare for a crash, such as on an aircraft; the instruction to "Brace for impact!" or "Brace! Brace!" is often given if the aircraft must make an emergency landing on land or water. There are many different ways to adopt the brace position, with many countries adopting their own version based on research performed by their own aviation authority or that of other countries. The most common in passenger airliners being the forward-facing seat version, in which the person bracing places their head against or as close as possible to the surface it is likely to strike (and in the process bending over to some degree), placing their feet firmly on the floor, and their hands either on their head or the seat in front. Types of brace position There are many different ways to adopt the brace position, with many countries adopting their own version based on research performed by their own aviation authorit ...
