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 featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RAAF Aircraftswoman Providing A Safety Brief Onboard A KC-30
The Royal Australian Air Force (RAAF) is the principal aerial warfare force of Australia, a part of the Australian Defence Force (ADF) along with the Royal Australian Navy and the Australian Army. Constitutionally the governor-general of Australia is the de jure commander-in-chief of the Australian Defence Force. The Royal Australian Air Force is commanded by the Chief of Air Force (CAF), who is subordinate to the Chief of the Defence Force (CDF). The CAF is also directly responsible to the Minister for Defence, with the Department of Defence administering the ADF and the Air Force. Formed in March 1921, as the Australian Air Force, through the separation of the Australian Air Corps from the Army in January 1920, which in turn amalgamated the separate aerial services of both the Army and Navy. It directly continues the traditions of the Australian Flying Corps (AFC), the aviation corps of the Army that fought in the First World War and that was formed on 22 October 1912. ...

Comic Relief
Comic Relief is a British charity, founded in 1986 by the comedy scriptwriter Richard Curtis and comedian Sir Lenny Henry in response to the 1983–1985 famine in Ethiopia. The concept of Comic Relief was to get British comedians to make the public laugh, while raising money to help people around the world and in the United Kingdom. A new CEO, Samir Patel, was announced in January 2021. The highlight of Comic Relief's appeal is Red Nose Day, an annual (previously biennial) telethon held in March. The first live fundraising evening, held on 4 April 1986, featured comedians and pop stars, including Rowan Atkinson, Billy Connolly, Stephen Fry, Kate Bush and co-founder Lenny Henry. A prominent annual event on British television, Comic Relief is one of two high-profile telethon events held in the UK, the other being Children in Need, held annually in November. At the end of the Red Nose Day telethon on 14 March 2015, it was announced that in the 30-year history of Comic Reli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-heeled Shoe
High-heeled shoes, also known as high heels (colloquially shortened to heels), are a type of shoe with an upward-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 high heels in varying styles, heights, and materials. High heels have been used in various ways to convey nationality, professional affiliation, gender, and social status. High heels have been an important statement piece of fashion for centuries in the West. High heels spread from equestrian origins with the 10th century Persian galesh to wider fashion use. In early 17th-century Europe, high heels were a sign of masculinity and high social status. Towards the end of the century, the trend began to spread to women's fashion. By the 18th century, high-heeled shoes had split along gender lines. By this time, heels for men were chunky squares attached to riding boot ...

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 building or other structure is a special exit used during emergencies such as fires. The combined use of regular and emergency exits allows for faster evacuation, and emergency exits provide alternative means of evacuation if regular exits are inaccessible. Emergency exits must: * Be clearly marked (usually with signage that is normally illuminated, or is illuminated by a backup power source if central power fails) * Be in easily-accessible locations * Direct people to safe areas (usually outside) * Be regularly maintained and free of obstructions (they may not be used for storage) * Be secured to prevent unauthorized entry during normal operations An emergency exit's path usually ends in an outward-opening door with a crash bar with exit signs pointing to it. It is usually a door to an area outside of the building, but may also lead to an adjoining, fire-isolated structure with clear exits of its own. A fire escape is a special kind of emergency ...

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 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. The onset of turbulence can be predicted by the dimensionless Reynolds number, the ratio of kinetic energy to viscous damping ...

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 halts or crashes, the occupants continue at the same speed the vehicle was going before it stopped. A seat belt 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 ...

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 ...

Lingua Franca
A lingua franca (; ; for plurals see ), also known as a bridge language, common language, trade language, auxiliary language, link language or language of wider communication (LWC), is a Natural language, language systematically used to make communication possible between groups of people who do not share a First language, native language or dialect, particularly when it is a third language that is distinct from both of the speakers' native languages. Linguae francae have developed around the world throughout human history, sometimes for commercial reasons (so-called "trade languages" facilitated trade), but also for cultural, religious, diplomatic and administrative convenience, and as a means of exchanging information between scientists and other scholars of different nationalities. The term is taken from the medieval Mediterranean Lingua Franca, a Romance languages, Romance-based pidgin language used especially by traders in the Mediterranean Basin from the 11th to the 19th c ...

English Language
English is a West Germanic language that developed in early medieval England and has since become a English as a lingua franca, global lingua franca. The namesake of the language is the Angles (tribe), Angles, one of the Germanic peoples that Anglo-Saxon settlement of Britain, migrated to Britain after its End of Roman rule in Britain, Roman occupiers left. English is the list of languages by total number of speakers, most spoken language in the world, primarily due to the global influences of the former British Empire (succeeded by the Commonwealth of Nations) and the United States. English is the list of languages by number of native speakers, third-most spoken native language, after Mandarin Chinese and Spanish language, Spanish; it is also the most widely learned second language in the world, with more second-language speakers than native speakers. English is either the official language or one of the official languages in list of countries and territories where English ...
