NTSB Recommends FAA Update to Flight Call Sign Guidelines
The NTSB recommends the FAA amend procedures to address potential confusion from similar flight call signs.
The NTSB recommends that the Federal Aviation Administration amend Handbook 7110.65, "Air Traffic Control," to require controllers to notify supervisors when duplicate, phonetically similar, or potentially confusing flight call signs occur simultaneously on the same voice communication frequency. The recommendation aims to enhance safety by reducing the risk of miscommunication in air traffic control operations.
