Flying? The safest form of transport!!

WASHINGTON — At one time, airline safety generally meant one thing: avoiding a crash. But safety regulators are increasingly focusing on surviving one.

Starting this Autumn, all new airplanes will be required to have seats that will stay in place when subjected to stresses up to 16 times the force of gravity. The old seats had to meet stresses of only nine times the force of gravity. And, in a safety measure borrowed from automobiles, some seats will be equipped with air bags.

The combination of sturdy seats and air bags means that if a plane touches down short of the runway or rolls off the end of the runway and hits an obstruction, “You’re going to be conscious. You’re going to have the opportunity to survive,” said Bill Hagan, president of AmSafe, which makes the air bags.

In some airline crashes, the strength of the seats is irrelevant because the crash is not what the engineers call “survivable.” In other crashes, still violent but not as much so as exploding in midair or breaking up in flight, the passengers’ survival depends on suffering little or no injury in the first phase of the accident, as when a plane runs off the runway, and then getting out of the plane quickly to avoid a postcrash fire.

The new rules have taken effect gradually. Airplane models introduced after 1988 were required to have the new seats, known as “16g” seats. So planes like the Boeing 777 and the swarm of new regional jets all have them. But older models that were still in production were not required to have the seats.

The air bags borrow technology from automobiles. They are set off by a shock meter that comes directly from cars. And like the systems used in cars and trucks, the seat belt air bags in planes are designed not to deploy inappropriately — in cases of air turbulence, for example.

In fact, said Mr. Hagan, this is simple, because the air bag sensor system watches for shocks on the axis on which the plane is traveling; it does not monitor up-and-down or side-to-side movements of the kind produced by turbulence, he said.

The air bags are widely used in first- or business-class cabins, where the seat in front is too far away or angled in such a way that it cannot function as a cushion. In coach class, the air bag has started out for use in front rows, exit rows and bulkhead seats, near galleys or toilets. In other seats, the passenger gets some protection from the seat back directly ahead, which is designed to break in a controlled fashion, providing a cushion.

Singapore Airlines flies 777s with wide intervals between seats and uses the air bag, JAL, Cathay Pacific and Virgin also use them.

This time a Yemenia aircraft in the waters off Madagascar.  No idea yet as to cause as it is still early days but this "Fly By Wire" system is starting to worry me. Seems to me it was much better in the good old days when the pilot flew the plane and had a feel for what was happening and did not have to rely on a computer to tell him.

The Chinese-made A320 aircraft successfully completed a four-hour test flight earlier this year and was officially delivered at a ceremony on Tuesday delivered to Sichuan Airlines, a regional carrier based in southwestern China.  "We will build a strong future with the China aviation industry and for the China aviation industry," Airbus CEO Thomas Enders said. "(Airbus) will be working increasingly with our partners in China, setting new standards."

The Tianjin plant, which opened in September 2008, is modelled after a state-of-the-art Airbus factory in Hamburg and is a joint venture between Airbus and a Chinese aviation consortium and cost some 10 billion yuan ($1.47 billion).

China has been an Airbus customer since 1985. Since then, Chinese orders have exceeded 700 aircraft and will be supplemented by a further 10 models, scheduled to leave the Tianjin plant by the end of the year. Come 2011, the factory is expected to be turning out 4 aircraft per month. 

The Chinese aircraft market is the second largest in the world and already accounts for 15 percent of the European manufacturer's total sales. Chinese carriers are expected to purchase as many as 3,400 new aircraft in the coming two decades, and Airbus hopes to cash in on this by capturing half the Chinese market by 2012.

It's early days yet for news but according to Sky News there are 216 passengers and 12 crew on board the Airbus. A Paris airport official is quoted as saying "The plane disappeared from radar several hours ago. It could be a transponder problem but this kind of fault is very rare and the plane did not land when expected."

Now excuse me, is it common practice that when a plane falls off radar you just wait to see if it still arrives on time?  I for one would be getting other aircraft and ships on the area to look for it!!
