Q:<\/strong><\/p>\n

As FCOM, FLS beam is only appears in NPA. Actually we see it everyday in ILS approach.<\/p>\n

\"\"<\/a> \"\"<\/a><\/p>\n

Actual flight:<\/p>\n

\"\"<\/a> \"\"<\/a><\/p>\n

A:<\/strong><\/p>\n

The FLS beam is displayed only if a FLS approach is inserted in the FMS. If you insert an ILS approach the magenta dashed line displayed on the ND represents the LOC beam of the ILS.<\/p>\n

Q_2:<\/strong><\/p>\n

Magenta dashed line represents for LOC beam sounds reasonable. However, it seems no description for it in FCOM, at least not in 31-CDS chapter.<\/p>\n

A_2:<\/strong><\/p>\n

To clarify my previous answer. You were right when you said that you saw a FLS beam when flying an ILS approach. What you see is a consequence of the implementation of the FLS in your aircraft.<\/p>\n

FLS approaches can be LOC or ILS G\/S inoperative approaches and they are flown with LOC AND F-G\/S. The consequence is that all LOC of ILS approaches are coded with a LOC beam and are displayed even if you flight a full ILS.<\/p>\n

You can notice that on an ILS approach, the G\/S beam does not exist on the VD and it is only after deselecting the G\/S on the RAD\/NAV page that you can see the F-G\/S beam.<\/p>\n

To summarize, an FLS beam can be also a LOC beam and that is why they are describe only as FLS beam.<\/p>\n","protected":false},"excerpt":{"rendered":"
