Yes or no, you've ever actually shot a PAR to mins. Or any PAR.
Flown hundreds if not thousands under contract for controller proficiency training in all WX. Doing the math, I've given several thousand over my years in the military.

No it doesn't. One of the original selling points was that you didn't need lots additional equipment either on the ground or in the air. Most, not all, but most of the places I worked, there was no backup NAVAID. It was us or nothing. USAF got smart and started putting in ILS installations, took many years for Navy/Marine Corps to catch up.
Granted the FMS can be a challenge to the uninitiated... For about 25 hours.
Really? FMS issues are a constant source of problem in the airlines composed of both military and civilian aviators. "What's it doing now." Saying happens to more than someone with 25 hrs of FMS time.
We're you a nav/RIO/GIB/air crew or pilot in the mil?
