Can GPS be *too* accurate? Do I need some XTE??

receiving traffic advisories?

In the US and outside of class B airspace, it is the pilot, not ATC,
who is ultimately responsible for IFR/VFR traffic separation. A VFR
traffic advisory to an IFR aircraft is a courtesy offered by ATC; it
is not a guarantee.

You might want to rethink your reply.

A pilot in clouds or other IMC cannot provide separation to any traffic
he cannot see.



Neither can ATC - for example, when there is no Radar Coverage.

The system is designed to work even in those conditions, and the rules
follow suit...

In VMC, ALL pilots are required to "see and avoid", VFR or IFR.

VFR pilots are supposed to stay out of IMC to prevent getting hit by IFR
pilots on IFR flight plans in the IMC.

When there is no Radar, IFR separation is done using spacing and reporting
points. There are no traffic advisories, IFR or VFR.

VFR-to-IFR separation is a courtesy, as Peter said. If ATC calls out a
target to an IFR flight, and they are not talking to the VFR target too,
they can't even provide instructions that guarantee safe avoidance...


Don't take your advisories for granted. They are a favor.
