We did our first LPV approach in a turbine Bonanza at OSH today, with my
buddy as PIC and me acting as the safety pilot. His plane is equipped with a
Garmin 530W/430W combo, with GDL 69A and Stormscope, along with TCAS.

His autopilot has roll steering, and made all of the course and approach
turns (except a 90 degree turn from the IAF to the final approach course
when in approach mode). For this segment we probably should have kept it in
NAV mode, since the APP mode may not capture a turn greater than 45 degrees.
(at least this is what we figured)

The glide slope indication tracked perfectly (actually seemed less twitchy
than an ILS), and we flew it to mins.

On the missed approach the 530W and autopilot tracked the missed and entered
the hold with an appropriate tear drop entry. The shape of the hold depicted
on the nav page was egg shaped, as it should have been on a day with 40k
winds in the hold.

We did not have to do any knob turning at all for course guidance, except
for the suspend button at the DA.

On the way back we listened to XM satellite radio, and tuned in the local
metars from airports along our route.

With the 530W/430W combo we kept the 530 on the main nav page, with the 430
on the traffic page. On the approach we switched the 430 to terrain.

Depending on conditions we might have kept the 430 on the map page (not main
nav) for lightning or Nexrad info.

Overall, an outstanding combination of gear that make IFR flying a lot
easier.
