I am fully conversant with low viz operations and have operated the same over many years of international flying.
My point was and
remains still
An aircraft, with auto land capability, arrives at an aerodrome with un-forecast fog, declares an emergency (to ensure vehicles and aircraft remain clear of the ILS sensitive areas) and lands.
The QF crew did exactly what you would expect in the situation they found themselves and did it professionally and with the minimum amount of "pucker factor" ! (I love that phrase)
...........and for you
Shockwave.
In Cat 111a or b the only lights you will see (if any) could be the runway or taxiway,or highway.
You will not know which, until they come to dig you out of your cockpit.
One of these days you'll get the opportunity to upgrade to the LHS. When you do, two of the areas you'll be scrutinised on are decision making and risk management. Your statement above indicates to me you'll fail both of these critical areas of Command training.
The QF
Captain of the A330 demonstrated just why
he is that.
His options were:
1. Auto landing on a Cat I ILS runway.
2. Ditching.
3. Flying around until fuel exhaustion results in a forced (read: crash) landing.
He chose option 1. (good decision) This may have been based on the fact that options 2 & 3 posed a greater threat to himself and passengers than option 1. (good risk assessment).
Have a nice day
