Dubai, UAE, 16 September 2021 – To support its planned ramp-up operations, Emirates has begun a worldwide campaign to recruit 3,000 cabin crew and 500 airport services employees to join its Dubai hub over the next six months.
These roles are Dubai-based positions and frontline customer-facing roles, and both jobs offer exciting opportunities for friendly, energetic, and service-oriented people to meet and interact with the world as Emirates’ brand ambassadors. Candidates interested in joining Emirates as cabin crew or as an airport services agent can find out more about the job requirements and submit their application on www.emiratesgroupcareers.com.
Emirates has gradually restored its network operations in line with the easing of travel restrictions around the world, and over the past months, it has been recalling pilots, cabin crew and other operational employees who were stood down when the pandemic forced a drastic reduction in flights last year.
The airline currently flies to over 120 cities, representing 90% of its pre-pandemic network, and it plans to restore 70% of its capacity by the end of the year, including bringing back more of its iconic A380 aircraft into active service.
One of the most dynamic global cities, Dubai has also led the world in its response to the pandemic thanks to its strong leadership and public-private sector cooperation. The rapid vaccination roll-out in the United Arab Emirates, and clear pandemic protocols have enabled Dubai to quickly and safely re-open to international tourism and business activities since July 2020.
Dubai continues to attract people from all over the world with its welcoming culture, tax-free environment, and leading infrastructure for living, working and recreation.
Every time a tragic aviation accident occurs, you’re likely to hear the news mention something about the hunt for the plane’s black boxes. These units are said to contain vital information that can reveal why a particular airplane might have crashed. Since the 1950s, the data inside black boxes has helped accident investigators, airline manufacturers, and aviation professionals improve flight safety for everyone.
A Black Box is able to withstand many accident scenarios without sustaining damage. Before being put into use, they are tested to see if they can withstand an impact with a concrete wall at 750 kilometers per hour (about 466 miles/hour), a static load of 2.25 tons for at least five minutes, a maximum temperature 1,100 degrees Celsius (2,012 Fahrenheit) for one hour and water pressure found in depths of up to 6,000 meters (about 19,700 feet).
They are a significant contribution to airline safety, but have you ever wondered how they actually work
1. They’re actually made of two components: the flight data recorder and cockpit voice recorder.
Technically there isn’t one single “black box” on each plane. Instead, there are two parts — the flight data recorder (FDR), and the cockpit voice recorder (CVR). During a flight, the FDR tracks information about the plane itself, like its direction and speed, while the CVR records audio of the crew’s conversations, radio transmissions, engine sounds, and alarm noises.
Sometimes they can be combined together inone unit, but they are often two separate devices. They’re also quite expensive to make. The standard flight data and cockpit voice recorder system can cost anywhere from $10,000 to $15,000 to produce.
2.Human error is one of the primary reasons black boxes exist.
It’s true that inventions are born out of human necessity. In the 1950s, an Australian research scientist named David Warren helped to investigate the repeated plane crashes of the first commercial jet airliner, The Comet. He proposed that if researchers had knowledge of what happened on the plane moments before it went down, it would help them figure out how to improve the next flight.
While mechanical failure is a very real possibility, it’s been noted by several sources that the most common cause of airline crashes is pilot mistake. This is arguably why the CVR (cockpit voice recorder) exists, and not solely the flight data recorder.
3.The locations of black boxes can be traced in the bottom of deep oceans thanks to a special tracking component.
Every flight data recorder contains a tool called an underwater location beacon (ULB). This makes it possible for investigators tofind it if a plane crashes into a body of water. Once underwater, it sends out an acoustic signal that searchers can detect with a special receiver.
Finding the FDR and CVR from a plane that’s crashed into an ocean can still be tricky. In order for the signal to be heard, one has to be within a 15-mile range of the beacon. On top of that, the battery life only lasts for 30 days after it’sbeen submerged.
However, it’s not impossible. Two years after the 1987 crash of South African Airways295, investigators found the plane’s cockpit voice recorder 16,000 feet below the surface.
4.Black boxes are usually placed in the airplane’s tail because that’s where the least damage will occurs.
Even though the CVR records cockpit audio, the recording device itself doesn’t sit up front with the pilots. Typically the pilot area is fitted with several microphones, but the actual device that stores the recordings is hidden in the tail of the plane. This prevents the FDR and CVR from being completely destroyed in a crash since the tail typically feels the impact last.
As Joe Janes of the Information School at The University of Washington said, “Planes rarely back into mountains.”
The Australian Transport Safety Bureau reports that flight data recorders can withstand fires up to 1,100 degrees Celsiusand a continuous pressure force of 5,000 pounds for up to five minutes. In addition, they can endure water pressure at depths up to 20,000 feet.
6.Only a special committee is allowed to listen to black box data.
Once an FDR or CVR has been recovered from a plane crash site, it gets transported to a special lab for analysis. After the data is extracted, a panel of exclusive aviation VIPs, everyone from industry experts, airplane manufacturers, and FAA officials, meet to review its contents. They then piece together the audio recordings and information from the FDR and try to deduce what happened in the moments leading up to an incident. The rules regarding who gets to be involved in the investigation are very strict and highly regulated by The US National Transportation Safety Board.
In fact, the US Congress explicitly forbids CVR audio recordings from being released to the public. They only publish the written transcript of the CVR data after the official safety hearing occurs.
What are the colors black box?
Although they are called ‘black boxes,’ aviation recorders are actually painted bright orange. This distinct color, along with the strips of reflective tape attached to the recorders’ exteriors, help investigators locate the black boxes following an accident. These are especially helpful when a plane lands in the water.
You might have visit the airport and seen an aircraft parked or probably you have used it as a form of transport from one destination to another and may be wondering why an airplane has wings as compare to other form of transport.
Well, Wing in aeronautics is an airfoil that helps lift a heavier-than-air craft. When positioned above the fuselage (high wings), wings provide an unrestricted view below and good lateral stability. Parasol wings, placed on struts high above the fuselage of seaplanes, help keep the engine from water spray.
Wings are mostly constructed using aluminum but they can also be made using wood covered with fabric. Some aircrafts wings are made using a magnesium alloy. In modern aircrafts, stronger and lighter materials are used in wing constructions and throughout the airframe.
Wings made of carbon fiber also exist and there are also aircraft wings that are made using a combination of materials to provide maximum strength.
The internal structures of aircrafts wings are usually made of stringers and spars running spanwise and formers or bulkheads and ribs running chordwise – leading edge to trailing edge.
Spars are important structural members of an aircraft wings. They support distributed loads and concentrated weights like the landing gear, engines, and fuselage.
The skin carries part of the load imposed during flight. It is also responsible for transferring the stress to wing ribs.
