411A,
You make a valid point. Fully stabilised, visual, CAVOK, on the ILS (where applicable), spot on with VASI/PAPI, whatever, and the computer tells you that you're unsafe.
Option 1 -
Continue with a perfectly stable approach using all visual clues and other aids.
Option 2 -
Spend the next 15 mins p155ing about in the valley, surrounded by cumulo-granite, in a high workload environment, even though you know the computer is wrong.
Tell me, which is the safest option?
SESMA is great, and I would never want to condone over-riding computer warnings without valid cause, but equally we can't take the human totally out of the equation.
