AeroSafety World July 2010
68 pages. [PDF 4.6M]

Checklists and monitoring are designed to counteract the possibility of human error in the cockpit. But while essential, they are not infallible. Benjamin A. Berman and R. Key Dismukes observed line operations during 60 flights to determine whether deviations from SOPs slip through. They recorded 899 deviations, 194 in checklist use and 314 in operating procedures. They describe specific causes such as omission of standard callouts and general principles behind the errors.

Also in the July issue, Wayne Rosenkrans looks at factors in the evacuation of the US Airways A320 that ditched in the Hudson River; Mark Lacagnina writes about the spatial disorientation, exacerbated by inadequate CRM and a lack of aircraft handling skills, in the 2008 crash that killed all occupants of a 737-500 at Perm, Russia; plus other feature stories and standard departments.

Features
 

Designing a Better Error Trap (Text only)

Airlines should examine their SOPs to specifically define the objectives of each procedure and to determine whether it is realistic to assume that pilots can perform the procedure reliably under actual line conditions. Pilots must be aware that in deviating from any procedure, they might be giving up safety margin that is not apparent. [Download PDF 6 pages. 357K]

Misgauged Recovery. (Text only)

Spatial disorientation was the primary cause of the Sept. 13, 2008, crash of a Boeing 737-500 at Perm, Russia, according to the final report by the Russian Air Accident Investigation Commission. Contributing factors were inadequate crew resource management (CRM), a lack of proficiency in basic aircraft handling and a lack of skills associated with the use of a “Western-type” attitude indicator for recovery from an upset.

Survival on the Hudson. (Text only)

The lessons learned reflected the importance of leaving as little to chance as possible in preparations to survive an aircraft accident. The investigation revealed that the success of this ditching mostly resulted from a series of fortuitous circumstances, including that the ditching occurred in good visibility conditions on calm water and was executed by a very experienced flight crew.

Diminishing Skills? (Text only)

With the advent of advanced, highly automated cockpits in current transport category jet aircraft, pilots no longer fly solely by reference to raw data from airplane instruments, and as a result, their basic instrument flying skills may have diminished. [Download PDF 5 pages. 217K]

Fractures Blade. (Text only)

The fatigue fracture of an Aerospatiale AS 350D power turbine blade caused a loss of engine power that led to the May 24, 2008, fatal crash of an Island Express Helicopters air taxi flight on Santa Catalina Island off the coast of California, the U.S. National Transportation Safety Board says.

Virtually Interactive. (Text only)

Efforts to computer-generate air traffic control environments inside flight simulation training devices have advanced significantly in step with an emerging consensus about the benefits, several specialists say. The airline industry has spent about six years considering systems and methods that would go far beyond current training of candidates for the multi-crew pilot license in a few countries.

Joint Cognitive Systems. (Text only)

Cognitive task design today enables innovative solutions to such problems. Crew resource management, one of the most familiar examples of cognitive task design, originated partly from the idea that flight attendants should function as extra eyes and ears for two-pilot flight decks.

Info Scan | Night Light. (Text only)

The investigation determined that the pilot flying was likely to have been relying on peripheral vision while steering because of the need to concentrate on the forward view; that the rolling takeoff reduced the time available to check position; and that the pilot was misled by “confusing aerodrome markings especially taxiway lead-in lines that directed aircraft onto the runway edge lights, resulting in the misalignment of the aircraft at the beginning of the takeoff roll.” [Download PDF 4 pages. 163K]
