Let me clarify one thing please. I new somebody was going to jump on the" below vasi thing " that's why I added no lectures please but I should have explained myself in more detail. When the gentleman wrote asking about techniques into and out of Aspen and Telluride I felt I could share with him some of mine. Some things I assumed: Since he is flying in on a business jet I assumed he was not part 121. That leaves him 135 or 91. In part 91 ops there is nothing wrong with going below vasi to assure a safe landing( part 91.129e3). I am assuming that he will use his/her own good judgement and not rely on my tips. Hopefully after a nice landing he can say, ahh I see what he means. , As far as the Aspen crash goes, the captain could have done only two things. he either called the field in sight when he didn't have it, because of the reported vis, figuring he'll see it soon, or he lost it after passing the MAP. Once you pass MAP at ASE, you're toast. That's why I said the instrument approach is self explanatory. You follow what the plate says. Now I also agree that 121ops are safer than other ops and its wonderful that you can get that kind of training for going into certain airports. Like most other pilots, the first time I flew into an airport is actually in the airplane itself. I've flown into Tegu, Bogota,Cusco Peru, numerous European, African, Middle East, and Asian airports safely, only one required a safety pilot on board ( CuscoPeru ) I still consider myself a safety oriented pilot. One more thing, please no " assumed " lectures.
