I concure. The Tacan 07 to Wiesbaden AAF begins with a DME Arc. Frankfurt approach always sends us to the fix that begins the approach.

The only thing I need the RMI for is confirming the fix and locating the lead radial to turn and intercept the final course. Otherwise, I fly the DME. Numbers get bigger, turn in towards the Tacan. Numbers get smaller, hold the heading and wait to reintercept the arc. The whole turn ten tune ten thing works fairly well too, but it really isn't necessary.
