Questions about a medevac flight accident in adverse conditions

Martes, 28 de agosto de 2012 Laura Duque Arrubla Sin comentarios

Pressure to conduct EMS operations safely and quickly in various 聽enviromental聽conditions- for example, in inclement weather and at night- increases the risk of accidents when compared to other types of patient transport methods, including ground ambulances or commercial flights. In this accident report, NTSB said, 鈥淭he pilot did not maintain sufficient airspeed during an instrument approach in icing conditions, which resulted in an aerodynamic stall and loss of control. Contributing to the accident were the pilot鈥檚 fatigue, the operator鈥檚 decision to initiate the flight without conducting a formal risk assessment that included time of day, weather and crew rest, and the lack of guidelines for the medical community to determine the appropriate mode of transportation for patients.

This month, CallBack from NASA`s Aviation Safety Report System takes a look at how the urge to press on to ones`s destination, despite conditions that might otherwise discourage such a decision, can lead to risky behavior and undesirable consequences. Four pilots who let “ge麓-home-itis” cloud their thinking share valuable insights into avoiding this dangerous malady.

The “toxic” Captain : How to identify?

Lunes, 16 de abril de 2012 Laura Duque Arrubla Sin comentarios

Shortly after聽take off from Douala, Cameroon, the pilots of a B737 from Kenya Airlines lost its control . The captain experienced confusion and spatial disorientation and the aircraft entered in an unrecovered spiral dive. Inadecuate operational control, lack of crew coordination and non adherence to standard procedures were among the causes according to Civil Aviation authorities.聽Research about captain established certain personality traits as “Toxic” Captain capable to make a cockpit environment that can be a safety risk.聽 Let us learn to prevent these behaviors.

Toxic captain:

  • strong character and heightened ego;
  • authoritative and domineering attitude with subordinates;
  • paternalistic attitude;
  • deficiencies in CRM;
  • a 鈥渢ouch of arrogance

Midair Collisions: “See and Avoid”

Mi茅rcoles, 21 de septiembre de 2011 Laura Duque Arrubla Sin comentarios

The number of midair collisions in the United States has averaged 30 per year since 1978, generally involving general aviation aircrafts, but by no means other operators are inmune. In the preceding 12 month period, over 4.000 in-flihght traffic collisions were reported to NASA-ASRS. The following ASRS reports published at CallBack September issue show that the “See and Avoid” principle remains a crucial aspect of collision avoidance in visual conditions

On the Home Front: “A stressful family life can affect performance in the cockpit”

Mi茅rcoles, 17 de agosto de 2011 Laura Duque Arrubla Sin comentarios

The results of this study indicate 聽that stability in relationships and home life were the most important factors in helping pilots cope with stress and 聽that the effects of domestic stress carry over to the pilots鈥 work world, directly influencing work stress and indirectly affecting pilots鈥 perceptions of their flying performance鈥.suggesting the need for management to maintain awareness of how the quality of home life may affect the work environment and overall performance.

Citing a 鈥渄isturbing number鈥 of events involving nonadherence with standard operating procedures by pilots and air traffic controllers, the U.S. National Transportation Safety Board is complaining of 鈥渁n erosion of 鈥 professionalism鈥 and urging action to improve on-the-job behavior.

Huh, Woa and Phew

Lunes, 18 de abril de 2011 Laura Duque Arrubla Sin comentarios

It is no any gibberish, just the three words associated with the TEM (Threat and Error Management) process. From aviation safety perpective, Huh? is the most important, because is an identifier of a potential threat聽 or hazard. The second Woa is followed by an exclamation and is oftenly spoken when the first was ignored, in this case the hazard exists or has existed. And third, Phew is spoken when threat is has already passed. All these are process that are at the heart of TEM. Find out more in this peculiar article published very recently at FSF

Listen to the Little Voice…

Viernes, 4 de marzo de 2011 Laura Duque Arrubla Sin comentarios

ASRS report narratives frequently contain references to a 鈥渓ittle voice鈥 that offers timely advice. The voice, of course, resides within the mind of the reporter and is usually the voice of experience or sometimes just the 鈥渧ocalization鈥 of a gut feeling. Here from the last CALLBACK from NASA’s Aviation Safety Report System(ASRS) you can read several cases from pilots to air traffic controller.

Designing a Better Error Trap

Martes, 17 de agosto de 2010 Laura Duque Arrubla Sin comentarios

As can be read in last AerosafetyWorld聽issue from Flight Safety Foundation, crew observations show that checklists and monitoring are not as effective as generally assumed. Although accidents like Helios Airways B737 on 2005 are fortunately extremely rare, they point to the crucial roles played by checklists and monitoring in helping pilots catch system malfunctions and human error and manage the challenging situations that sometimes arise on routine flights….
