Seems an excellent result, in the circumstances. I was instructed in how to use all the navaids in the aircraft as a matter of course during my PPL navigation training, but perhaps the transition to GNSS makes the ADF/VOR/DME navaids less relevant. Regardless, though, keeping the VFR pilot calm and getting him safely out of cloud is far more important than whether he would have been able to fly an intercept and perhaps find his own way out.
