Semi-Automatic Cross-Checking between Different Copies of the Same Flight Plan,
Abstract
A flight-plan usually exists in several different forms, in the aircraft flight management system, as hard copy on the flight-deck, in one or more ATC data processors, and distributed over flight-progress strips (or their electronic equivalents) in one or more control centres. Any discrepancies between various versions of the plan are potentially hazardous. Given that the flight plan is already stored, for one reason or another, in at least one computer, it is proposed that each computer should also be used to generate a 'check word' which can easily and rapidly be compared with that stored as hard-copy or in some other machine. The check word might consist of four alpha characters which can easily be remembered and passed by voice. The paper discusses possible algorithms for generating check-words, and gives the results of some laboratory trials of a prototype system.
