I flew the T-37, it had no gps, no AOA, and I was GQ when it came to flying a TACAN approach because that was essentially our bread and butter. We did have an ILS, but I'd say we trained to the TACAN approach more. I learned more about a TACAN approach procedurely in Primary than was ever tought/briefed/expected anywhere else I've been, and not because they already assumed I knew it. A PAR/ASR approach is so easy it should be one of the least things they ever show you, I did my only one in Primary into Carswell JRB in Fort Worth, weather was 400-1.5, thunderstorm had just past and were expected to roll through again in about 35 minutes. We did a touch-n-go and went over to Alliance, radar vectors for the ILS, Alliance was calling like 400-2, we broke out much much lower. All while my IP had gotten a bad case of the leans when we went into the goo over College Station, and this was all at night. This is favorite story to tell from Primary, it has more but this is the quick version. Point. AOA and PAR approached are not difficult and taught ad nauseum.....my new favorite word...in Advanced anyways. I have a Master's Degree....I feel....in how to fly AOA, and I still suck.
