Sounds to me like the PC1 "Problem" is a stupid assed Rule that has no basis in reality.....just another bureaucratic edict handed down and swallowed whole by the Operators.
I suppose there is an appeal process or some way to challenge it.....isn't there?
Can someone calculate the probability of both an Engine Failure and a Goggle Failure at a "Critical Point" of a Landing?
It would be the same for a Takeoff I would assume.
I do believe we are talking about a very damn small chance of that event ever happening at all....much less it resulting in the loss of an aircraft....even if that would happen as a result of said goggle failure.
Turning on a White Light, a Landing Light or Night Sun, does not harm the usefulness of NVG's.....or operating around ground based white light. Modern NVG's work fine with minimal "Wash Out".
