BALTIMORE, Aug. 22 (UPI) -- Researchers say civilian helicopter crash-resistance standards are not as effective as military helicopter standards.
Researchers at the Johns Hopkins Bloomberg School of Public Health Center for Injury Research and Policy said the civil standards might be less effective than anticipated when they were established in 1994.
The study is the first to determine the effectiveness of the standards.
Although crash-resistant fuel systems have been nearly 100 percent effective in survivable crashes of military helicopters, manufacturers and regulators of civil aircraft have been slow to implement the technology in civilian helicopters, said Dr. Dennis Shanahan, corresponding author of the study and an associate in the Johns Hopkins Bloomberg School of Public Health's Department of Health Policy and Management.
The research findings are published in the August issue of the journal Aviation, Space and Environmental Medicine.
