Do you compare reported visibility to the distance from the runway to the VDP? It might tell you that a missed approach is in the cards, even when the procedure is above minimums.
Say you’re flying to Asheville, North Carolina on a rainy IMC day. The visibility is hovering around a mile and a half and the ceiling is 1200 feet. ATC has you on vectors for the RNAV (GPS) RWY 34. Without a WAAS GPS in your Turbo Bugsmasher, you’re stuck with the LNAV minimums. The weather is above the Category B minimums that you’ll be using, so you shouldn’t have any problems. Right?
