The Federal Aviation Administration, or FAA, the government agency that regulates civil aviation in the United States, announced new rules this month to fight pilot tiredness. The new guidelines, which will go into effect in two years, call for reducing the number of pilots’ on-duty hours and giving them a 10-hour rest period between shifts, so they can get at least 8 hours of sleep. The new rules apply to only pilots of passenger airlines. FAA determined that including pilots who fly cargo planes a large portion of the aviation industry would add too much to the cost of carrying out the changes. But the Independent Pilots Association has taken legal action asking the government to set one level of safety for all pilots.
