Keeping It Up Longer
March 2012 was another great edition. I enjoyed the discussion of the Santa Maria LOC DME (BACK CRS)-A approach (“The Right Time to Descend”), and I was happy to find that I agreed with your legal interpretation. However, I came to a different end conclusion.
I applaud the pilot’s initial decision to ask for the approach in order to avoid terrain, but then to discard that decision based on seeing the VASI and runway is a setup for a classic black-hole CFIT accident. Just because you can see the runway doesn’t mean you can see the terrain. Your fist indication of terrain may be the VASI and runway starting to disappear—and by then it may be too late.
