Most of approaches that have radius-to-fix (curved) legs usually requires authorization to fly so I’ve heard some pilots equating RF legs to authorization required but that’s not actually true. You can find a non-AR (Authorization Required) RF approach at KCRQ. Look at the RNAV (GPS) X RWY 24 approach here.

There are even some ILS approaches incorporates RF legs to guide you onto localizer, such as KRNO ILS Z 17R.

If your GPS supports it, then you should be able to load this approach and use autopilot to fly it (like Garmin NXi series).
