Aviation Safety Culture: Effective Risk Management




Safety Culture is an essential to success and key to accomplishing future goals in your organization to avoid and prevent future incidents and accidents.

Usually, Aviation Safety has been regulated strictly to follow up the Rules, Regulations and Standards Operation Procedures (SOP).

ICAO itself distinguishes between state Safety Programs (SSPs) and Safety Management Systems (SMSs) for air operators and maintenance organizations. 

SMS is a systematic approach to managing safety, including the necessary organizational structure, accountabilities, policies and procedures.

It follows that safety is the state in which the risk of harm to persons or property is maintained at or below an acceptable level. Human error is inevitable, and absolute Safety is First .

These are set as the Safety Goals for operators to maintain and stay away of accidents.

How important is a Safety Culture for your organization?

Safety Culture is the set of continuing with values and attitudes concerning safety, shared by every member of every level of an organization. Safety culture is usually recognized as critical to the success of SMS.

We cannot let down Air Safety in our Country. Safety is Everybody’s Business !!!



Airline Industry at Its Safest Since the Dawn of the Jet Age




Flying on a Commercial Jetliner has never been safer.

It will be four years on Tuesday since the last fatal crash in the United States, a record unmatched since propeller planes gave way to the jet age more than half a century ago. Globally, last year was the safest since 1945, with 23 deadly accidents and 475 fatalities, according to the Aviation Safety Network, an accident researcher. That was less than half the 1,147 deaths, in 42 crashes, in 2000.

In the last five years, the death risk for passengers in the United States has been one in 45 million flights, according to Arnold Barnett, a professor of statistics at M.I.T. In other words, flying has become so reliable that a traveler could fly every day for an average of 123,000 years before being in a fatal crash, he said.

There are many reasons for this remarkable development. Planes and engines have become more reliable. Advanced navigation and warning technology has sharply reduced once-common accidents like midair collisions or crashes into mountains in poor visibility.

Regulators, pilots and airlines now share much more extensive information about flying hazards, with the goal of preventing accidents rather than just reacting to them. And when crashes do occur, passengers are now more likely to survive.

"The lessons of accidents used to be written in blood, where you had to have an accident, and you had to kill people to change procedures, or policy, or training," said Deborah Hersman, the chairwoman of the National Transportation Safety Board. "That's not the case anymore. We have a much more proactive approach to safety."

The grounding of the Boeing 787 fleet last month illustrates this new era of caution. The last time a fleet was grounded was 1979, after a McDonnell Douglas DC-10 crashed shortly after takeoff at O'Hare Airport in Chicago, killing 273 people. The 787s, by contrast, were grounded after two episodes involving smoke from batteries in which no one was hurt and no planes were lost.

The last fatal accident involving a commercial flight in the United States was Colgan Air Flight 3407, which crashed near Buffalo, killing 50 people, on Feb. 12, 2009. The pilot's maneuver was the opposite of what he should have done when ice formed on the wings.

Perhaps even more noteworthy, there has not been an accident involving a major domestic carrier since an American Airlines flight to the Dominican Republic crashed after takeoff in Queens in November 2001, killing all 260 people on board.

But while flying is safer, it is still not risk-free. Air traffic is set to grow in the next decade, and airports are more congested. Near-misses on runways and taxiways have risen. And with two million passengers in the United States boarding more than 30,000 flights every day, maintaining that safety record will be a challenge.

The Colgan accident also cast a troubling light on regional airlines, which hire young pilots, some with little experience, at a fraction of the salaries at bigger carriers. Since the crash, the Federal Aviation Administration has mandated longer resting periods for pilots. But in the face of opposition from airlines, it is still working on new rules for more extensive co-pilot training.

"It's important not to define safety as the absence of accidents," said Chesley B. Sullenberger III, the US Airways pilot who became a hero when he landed an Airbus A320 in the Hudson River in January 2009 after both engines lost power. All 155 aboard escaped.

"When we've been through a very safe period, it is easy to think it's because we are doing everything right," he said. "But it may be that we are doing some things right, but not everything. We can't relax."

Not long ago, the industry's safety record was far bleaker. In 1985, more than 2,000 people died in dozens of crashes, including 520 when a Boeing 747 crashed in Japan. A crash of a Delta Air Lines Lockheed TriStar killed 134 in Dallas that year.

After another series of accidents in 1996, federal officials set a goal of cutting accident rates by 80 percent over 10 years. That year, 340 people died in just two crashes in the United States - ValuJet Flight 592, a DC-9 that crashed in Florida, and TWA Flight 800, a Boeing 747 that blew up after its fuel tank exploded off Long Island.

Since then, the F.A.A., airlines and pilot groups have stepped up efforts to share safety concerns through a series of voluntary programs. Airlines agreed to participate after obtaining assurances that the information would not be used to discipline them.

An F.A.A. Web-based system, created in 2007, now includes information from 44 carriers. The result is widely viewed as successful, spawning an attitude that allows hazards to be identified before accidents occur.

The F.A.A. and airlines now systematically study data from flight recorders to analyze common problems, like finding the best angle of approach and speed to land at airports with tricky wind conditions.

Besides advances in navigation technology, today's airplanes are equipped with systems that can detect severe turbulence or wind shear, allowing pilots to avoid them altogether. Engines are also better built - when one fails, pilots can still land safely.

"We have engineered out the common causes of accidents," said Patrick Smith, a commercial pilot who writes a blog called Ask the Pilot.

And because planes have better hull and seat design, said Kevin Hiatt, the president of the Flight Safety Foundation, "crashes are more survivable today than decades ago."

In August 2005, for instance, an Air France flight to Toronto overshot the runway and burst into flames, yet all 309 passengers and crew managed to escape.

Aviation safety officials will also go to considerable lengths to learn what caused a crash. Uncertainty is rarely tolerated, said Peter Goelz, a former managing director at the National Transportation Safety Board.

After an Air France jet crashed in the Atlantic in 2009 on its way from Brazil to Paris, investigators spent nearly two years - and millions of dollars - looking for the flight data recorder. "Aviation, in particular, abhors a vacuum," Mr. Goelz said.

Mr. Smith said there was another reason for the safety record: "Luck is always going to be a part of it."

The biggest battle still being fought is over co-pilot training. The F.A.A. missed a Congressional deadline for new rules requiring first officers to have at least 1,500 hours of flying, the same as pilots, before being hired, instead of 250 hours today. The agency has proposed a compromise of 750 hours for former military pilots and 1,000 hours for pilots with an aviation college degree.

But the F.A.A.'s work has been slowed by lobbying by the airlines, according to a recent report by the Transportation Department's inspector general. Roger Cohen, president of the Regional Airline Association, said the F.A.A. should not set arbitrary numbers. "It's about quality training, not quantity," he said.

But Mr. Sullenberger said: "Some in industry still are fighting so hard to weaken, to delay or to kill an important safety initiative. The lessons of Colgan have not been learned."

Ray LaHood, the transportation secretary, said that the Colgan crash was his worst day in four years on the job, and that he had worked closely with family members of victims to strengthen the pilot training rules. Even though he plans to step down soon, he said, the F.A.A. is "going to continue to work to get that over the finish line."

The Top 10 Bird Strike Myths


Bird Strike Committee USA


The Top 10 Bird Strike Myths


There are many Misconceptions by Air Travelers and the General Public about the threat posed by birds to aircraft and their occupants. The following facts should shed some light on some of these issues.

1.Myth - Bird strikes cannot cause serious airline accidents.
Fact - Since 1975, five large jet airliners have had major accidents where bird strikes played a significant role. In one case, about three dozen people were killed.

2. Myth - Bird strikes are rare.
Fact – Over 56,000 bird strikes to civil aircraft in the United States were reported to the Federal Aviation Administration (FAA) from 1990-2004, a mere 20% of the number that likely occurred.

3.Myth - Bird strikes are no more of a problem today than 20 or 30 years ago.
Fact - In North America, bird strike hazards are increasing. Because of outstanding wildlife conservation and environmental programs in North America, populations of many bird species have increased dramatically since the 1970s. Millions of acres have been set aside as wildlife refuges and strong environmental laws such as the Migratory Bird Treaty Act and the Federal Insecticide, Fungicide and Rodenticide Act have protected birds and other wildlife. As a result, species like non-migratory Canada Geese, which frequent urban areas such as golf courses, parks, and airports, have more than quadrupled in number from 1985 to 2004. As another example, the double-crested cormorant population on the Great Lakes has increased over 1,000-fold, from 89 nesting pairs in 1972 to over 115,000 pairs in 2004. These increases have led to an increase in the number of birds in the vicinity of both large and small airports and greater opportunities for birds, especially larger birds, to hit aircraft.

4.Myth - Large aircraft are built to withstand all bird strikes.
Fact - Large commercial aircraft like passenger jets are certified to be able to continue flying after impacting a 4-lb bird, even if substantial and costly damage occurs and even if one engine has to be shut down.  However, 36 species of birds in North America weigh over 4 lbs and most of these large birds travel in flocks.  About 30% of reported strikes by birds weighing more than 4 lbs to civil aircraft in USA, 1990-2002, involved multiple birds.  Even flocks of small birds (e.g., starlings, blackbirds) and single medium sized birds (e.g., gulls, ducks, hawks) can cause engine failure and substantial damage.

5.Myth - If a bird flies into an engine during takeoff and the engine quits, the airplane will crash.
Fact - Large commercial jets are designed so that if any 1 engine is unable to continue generating thrust, the airplane will have enough power from the remaining engine or engines to safely complete the flight.  However, because many birds travel in flocks, there is always a possibility that birds will be ingested into multiple engines.

6.Myth - Nothing can be done to keep birds away from airports.
Fact - There are a number of effective techniques that can reduce the number of birds in the airport area. In general, the techniques fall into three categories: making the environment unattractive for birds, scaring the birds, or as a last resort, reducing the bird population.

7.Myth - It is illegal to kill birds just to protect aircraft.
Fact - In North America, there are a few introduced (non-native) birds such as pigeons and starlings which are not federally protected species and generally may be killed if they pose a threat to aircraft. Most birds, such as ducks, geese, gulls, and herons, may be killed in limited number by an airport authority only after obtaining appropriate permits and demonstrating that non-lethal techniques are not adequate. Endangered species may not be killed under any circumstances.

8.Myth - If birds are a problem at an airport, killing them all would eliminate the problem.
Fact - Even if it were legal to do so, killing off all birds at an airport will not solve the problem.
 An airport is an integral part of the local ecosystem and like in all ecosystems, each plant or animal species plays an important role. Eliminating any one problem species will only lead to some other species taking its place. A combination of bird control measures which take into account habitat management is a superior long-term solution.

9.Myth - Except for the very rare accident, bird strikes are only a nuisance to airline operators.
Fact - For a modern jet airliner, even minor damage can lead to significant costs. For example, if a bird strike results in damage that leads to replacing a single pair of fan blades, the airline has to deal with not only the direct cost of labor and materials, but also the indirect costs of keeping the aircraft out of revenue service and redirecting passengers. The FAA estimates that bird strikes cost civil aviation over $500 million per year in the USA, 1990-2003. Worldwide, bird strikes cost commercial air carriers over $1 billion each year. Furthermore, minor damage to airliners is usually not covered by aircraft hull or engine insurance, so the costs of most bird strikes directly affect airline profits.

10.Myth - Bird strikes are a concern only to those who fly.
Fact - The issue of bird strikes is tied into a wide range of social and policy issues that go beyond aviation. The most important areas where this is true is the environment. Past and present policies of wildlife and habitat management can directly affect bird populations and bird strike hazards. Because bird strikes can lead to aircraft accidents, bird strikes can have a direct effect on both the families and friends of potential victims both in the aircraft and on the ground. Bird strikes can also have environmental consequences. For example, as a result of a bird strike that disabled an engine on a B-747 departing Los Angeles International Airport (LAX) in August 2000, the pilot had to dump 83 tons of fuel over the Pacific Ocean before returning to land safely at LAX.

Bonus Myth – Bird strikes never occur at high altitudes.
Fact – It is true that most strikes occur in the airport environment.  About 41% of reported strikes with civil aircraft in USA occur while the aircraft is on the ground during take-off or landing and about 75% of strikes occur at less than 500 feet above ground level (AGL).  However, over 1,300 strikes involving civil aircraft at heights above 5,000 feet AGL were reported from 1990-2003.  The world height record for a strike is 37,000 feet.

Future Technology: Runway Overrun Protection Systems


Runway Overrun Protection Systems

                                             

                                              
Runway Excursion 


This might be a bit off topic, but while looking at Safety nets I came across Runway Overrun Protection Systems (ROPS). Runway Excursion is of serious concern to the Aviation Industry at the moment because occurrences are increasing at a rate greater than the rate of global fleet expansion. Put simply, runway excursion is an incident where an aircraft unintentionally leaves the runway and can occur during takeoff or landing phases of flight – ICAO defines runway excursion as “A veer off or overrun off the runway surface”.  

ROPS shows the position at which the aircraft will stop along the runway (in wet or dry conditions) on the aircraft’s nav display.

The point will move along the length of the runway depending on the systems evaluation of aircraft approach profile, aircraft breaking capability and landing distance available (LDA).

If ROPS predicts a Runway Overrun Occurrence a visual warning is given to the pilot, along with a repeated aural alert: “RUNWAY TOO SHORT”. Research has shown that when pilots are presented with a non-standard situation, their instant reaction is to revert to a pre-programmed response.

In the event of runway overrun it has been found that pilots have often reduced reverse thrust to idle upon reaching 80kts, a standard procedure, rather than reacting to the non-standard situation in front of them. For this reason, the ROPS system gives the aural cue “KEEP MAX REVERSE” if the aircraft is at risk of runway overrun and is approaching 80kts.

Airbus has made their ROPS system commercially available to other aircraft manufacturers in an attempt to combat the number of global runway excursion incidents. 

Today, Main Cause of Accidents is Runway Excursion
A Vast Majority of Overruns at Landing is Preventable

Main Contributing Factors of Runway Overrun at Landing


Auto Brake setting too Low.
Stabilization Not Achieved at 1000/500 ft.
Wind shear at low altitude.
Approach becoming unstable at low altitude.
Long flare.
Long derotation.
Late selection of engine thrust reversers.
Cancellation of reversers at 70kts.
Late/weak manual braking (w/o or after AB disc).
Failure affecting the landing distances.
Runway friction coefficient lower than expected.
Etc.
