Well, I'm hand-flying most of the approaches, and the CDI is generally
centered prior to the FAF, so I wouldn't note a sudden change in
sensitivity on the final segment.

I do, of course, note the change going from enroute to terminal mode, and
from terminal to approach mode if I have any CDI deflection.

I am playing with the new Garmin 400/500W trainer and the needle
movement is very smooth.

I also verified the great difference between when the scaling becomes
localizer-like with VTF and own-nav.

I flew the LPV into KIXD Runway 36. Using VTF, I did an intercept 8
miles prior to JIKLA (the FAF). The CDI scaling was already well below
1 mile. Then I did an intercept at the same position with ANQUIM (the
IF) to JIKLA as the active leg. The needle came off the peg at 1 mile
crosstrack error.

The 530W also has a nice feature, not present in th 530. When there is
a course change at a waypoint it shows a broken magenta line, which is
the flyby course that will be flown if on autopilot. Positive course
gudiance in holds and procedure turns using highly accurate
roll-steering is great, too. (For FD or autopilot, those too need to
have roll steering to get the most out of these curved flight paths.)

I have no experience with anything other than the 480, so can't comment. I
also do not have a roll-steering a/p.

The 480 does show a solid curved magenta line for course changes at
waypoints representing the expected flight path.
