[Milsurplus] Navigation System

Hi, Sheldon,

> As for automated landings, the big guys have been
doing that for years.  Category II and III approaches
have to be flown with the couple autopilot systems,
the pilots are simply along for the ride, monitoring.

*nod* ... but during World War II, it wasn't quite so
commonplace.  ADF and ILS (and maybe backcourse ILS)
was as good as it got then.

> Category IIIc approaches are to zero visibility, and
they use the same localizer and glide slope
technology.

With a few extra toys to make it work pretty.  I
remember when the first Category III landing was made
... quite a big deal at the time.  I was happy to
master the ones I did (including my favorite, a GCA)
without dealing with what the big boys were doing. <G>

Best regards,

Michael, K3MXO
