Objectives of the committeeObjectives of the committee
• A research committee, commissioned by JCAB and supported by ATEC, was formed in order to - analyze turbulence related accidents, - review current status and - work out practical safety measures
• The committee members are from - National aerospace laboratory of Japan, - Aviation accident investigation commission, - Airlines and - Aircraft equipment manufacturers

Turbulence accidents analyzed Turbulence accidents analyzed by the committeeby the committee
• Reviewed 98 accidents occurred in USA, UK and Japan during 1997 - 2002
• 143 persons injured seriously and one person fatally (57 passengers and 87 flight attendants injured seriously, and 1 passenger injured fatally)
• Flight attendants are 36 times more likely to be injured than passengers

Signs of violent joltsSigns of violent jolts
• Of 10 turbulence related accidents in Japan, - Jolted all of a sudden ……………………….…1 case - Sustained vibration were felt beforehand.…...3 cases - Vibration began 2 to 4 seconds before……..…6 cases
• In many cases, signs of violent jolts are perceivable, even for a CAT.
• Handholds that give quick grip would be effective to mitigate turbulence related injuries.
