True in this case. But what about the new trains on Southern that
have to get a GPS signal or they chuck a wobbly, aircraft
navigation systems etc.

I thought (civilian) aircraft were not authorised to use GPS for
navigation.

To use it, or to depend on it?

Has that changed?

Not that i'm aware - i think that's one of the reasons for Galileo,
which will allow things like automatic landings. Once it's
operational, i'm off flying for good.

Yes, it won't be as much fun without all those crap landings by human
pilots.

But there's nothing new about automatic landings. I experienced my first
one on a BEA Trident at Heathrow about 40 years ago. They were
sufficiently rare then for all passengers to be presented with a gift to
mark the occasion (tie for men, scarf for women).
