ADS-B is going to be the ATC separation system. The movement is
probably irreversible. Austrialia (spelling?) is already a big
player.

Avoidance of passive obstacle in airspace not suitable for IFR
navigation will become more and more a cockpit responsibility as
technology advances. My Garmin 296 already does an awesome job, at
least in the U.S., where all the NACO-recorded obstacles are in the
database.


I don't have a 296, and neither do most pilots. My employer isn't likely
to put them in the hundreds of aircraft we fly, either. I do have a radio,
as do most aircraft.

The flip side is that the few thousand airliners all have EGPWS (TAWS).
So, the 900-pound ape is already taken care of.

A small point for the airlines flying IFR: the EGPWS platform doesn't
have recorded towers and buildings unless a modification call peaks and
obstacles has been added. I believe the pricy IFR-certified Garmin
system has all that stuff.

Since the 900-pound gorilla is using EGPWS/TAWS, no one is going to
spend for the system you mention.
