For certification to FMVSS213, car seat manufacturers self-certify. We utilize the same labs which the National Highway Traffic Safety Administration (NHTSA) uses combined with our own internal testing. The certification testing for aircraft travel is within the child restraint standard FMVSS213. NHTSA also tests our child restraint systems, which includes the certification to allow the statement certified for use in aircraft. However, NHTSA will not “certify” our child restraint systems, nor any other manufacturer’s child restraint systems. Not all car seat platforms meet the certification testing for aircraft use, such as our belt positioning booster seats. All DJG belt positioning booster seats are not aircraft certified and cannot be used while traveling on an aircraft.
