My point is that no pilot should put all his eggs in one basket, nor does
any autopilot system rely on one source of data, such as GPS. There are
also data that GPS simply cannot provide (like height above terrain). GPS
is not now, nor do I think it ever will be, the "be-all and end-all" for
aeronautical navigation. There will ALWAYS be backup systems to GPS,
primary systems to which GPS might be the backup, and systems which GPS
This is probably all moot, as others have pointed out that the Galileo web
site makes it clear that the aviation and other "safety of life" services
will be on channels well-removed from our allocations.
