Anyone flown atn LPV yet?

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.

According to the GNS430W manual, the unit does not provide positive course
guidance in holds except on the inbound leg, which is not a change from the
430, and does not provide positive course guidance on a PT except on the
outbound and inbound portions (not during the reversal itself), which is
also not a change from the 430.

Regarding roll steering, it says "For roll steering autopilots: roll
steering is terminated when approach mode is selected on the autopilot and
is available once the missed approach is initiated." I don't really
understand this statement.

I didn't read the 530W manual. Is it different?
