I have no trouble getting airliners safely on the runway in an ILS approach as long as I can program the FMC by feeding it with fixes consisting of a sequence of letters (ICAO)! E.g., approaching KJFK RW 13L the localizer is hit at CAXUN. However, many airport charts do not give such fixes but rather have ILS approaches marked by sequences like D11.3 - D8.3 - D3.7 - D2.3 and the like, as e.g. Paris Orly (LFPO). The FMC-Flightplans do not swallow these abbreviations. What is the correct way of programming such an approach?
