tor or pilot in command of an aircraft allow the operation of, any portable electronic device on any of the
following U.S.-registered civil aircraft. . .
“(b)(5) Any other portable electronic device that the operator of the aircraft has determined will not cause
interference with the navigation or communication system of the aircraft on which it is to be used.”
