Same for intercepts
I had always thought it was necessary (and prudent) to use raw data for the capture. However, during my last CQ training, I was instructed it was not necessary as the expanded mode provides sufficient information (and Progress page 2 gives offset from an FMS calculation). Since company standards don't specify what mode to be in for ILS approaches, and after thinking about your post, it may not be a bad idea to remain in raw data.
