I don't have nearly the experience level you have, but having just completed the Aviation Technology/Pilot Training program at University of Cincinnati and having just gotten my instrument rating, I would have to agree with your thinking and your actions. Part of CRM is identifying and speaking up when a possible error chain is being started. In my instrument I was taught that if you cannot confirm radio navigation TO YOUR FIX (you were landing on 24R, which had no radio navaid landing system), you cannot use that navaid. None of the ILS for 24L can legally be used for 24R. A visual approach is a VISUAL approach. The flying pilot should be looking at his/her sight picture of the runway, not the instruments (with exception of airspeed). Speaking out was the correct action, and I would hope you were able to continue the discussion after landing, preferrably out of public earshot. Maybe a review of the FAR/AIM was in order.
