GPS and old-fashioned thinking?

Also, it makes flight planning a breeze. No legs to figure. Just click
in your route, check for restricted/prohibited airspace and TFR's and
go direct!

Go to AvWeb and read Don Brown's columns about filing and flying direct.
If you use his advice, it makes the trip much more enjoyable and
contains potentially less surprises for everyone.

LASER ring gyros are certainly small enough, I don't know how much they
cost. If the US military can put them in artillery shells, they should
be available for light GA inertial nav systems.

We will be going to a GPS based system. Alaska has tried this system
under the Capstone name. Basically you will broadcast to ATC your
position and ATC will use that information just as they use the radar
information today.

Does LSA require and electrical system?
I have yet to see a handheld transponder for GA.

Googling for LRG prices surprisingly came up with mostly a blank, but I did
come up with one doc
(http://www.armadilloaerospace.com/n....ws?news_id=140)
that hints at a "6 figure price" for them. That same doc, however, talks
about commercially available Fiber Optic Gyros (which I don't know much
about) in the $1500-$2500 price range. There is an old adage, "Sooner or
later, anything made from silicon will cost $5", so I can only assume that
the days of affordable solid state gyros for GA are not too far off.

What do things like the Garmin G-1000 use?

No.

And you won't. The new system eliminates transponders.

Newps, are you going to pay for the cost to acquire and install this
system in my plane? If not, don't expect anywhere close to 100%
voluntary compliance.

What does it mean to "do away with primary radar"?

Most of the cost is related to maintaining the system. Once they
stop maintaining the long range primary radars, they might as well
just shut them off.

New NHL? what a joke

What does it mean to "do away with primary radar"? The antennae are
co-located and the systems are already built. What money would be saved by
turning the primary part of the system off? It's not even like they rotate
on different shafts so you can save a little on lubricating the bearings or
powering down the motor that makes it go round and round.

The antenna is a small part of the expense of maintaining a radar
system. Secondary radar is basically an antenna and some interagators.

The future thinkers want to do away with even the scondary and go do ADS-B.

Anyway, if we turn off the primary radar, we'll only be able to see things
that want to be seen. The libertarian in me likes that idea, but I'm
enough of a realist to understand that the people intent on blowing things
up are probably smart enough to turn their transponders off.

That is exactly the argument the security folks make, thus the primary
system is not going away for a long time.

Integrated solid-state Attitude and Heading Reference Systems (AHRS)

AHRS replaces gyros but doesn't have an inertial capability; at least
not yet.

No.

There has to be a transmitter of some type installed to broadcast.
