Yes.
Difference is, the initial report to start was above/better. It subsequently got worse, obviously.
Willingly starting an approach when it is reported as low below published minimums, on the hope that you’ll find that it was better weather sounds like bad juju.
I can count on two hands the times I have had to go missed at mins because we didn’t see the lights/runway/environment since 2007 at part 121. Of course, CAT III Autoland helps tremendously when we can accept 300RVR (VX) and 400 RVR (current shop), assuming a CAT III runway.
Risk averse thing. I’d rather start an approach that’s reported above mins, than start one below mins and hope that it is better than reported.
Now since my question went UN-answered numerous times, I’ll ask you or dustoff again:
Are there part 91 Corporate jet operations/companies that operate like 121, and go above/beyond 91 and match 121 rules/regs, and maybe even above 121? Because if I had to bet, I’d bet there are. And those are the better shops. And you would not be doing these kinds of ops at those shops, the same way you wouldn’t do it at my airline.
