Abstract : Very-low-frequency (vlf) radio signals offer potential advantages for aircraft area navigation. This document defines the aircraft navigation problem from the operational viewpoint and describes pertinent aspects of vlf propagation. Advantages and disadvantages of promising approaches to system design are noted. It is concluded that many system designs will provide true continental area navigation capability with redundancy and reliability. (Author)
