Nightvision for passengers?? That must be something Australian
.
Do you also tell the punters to stop reading the paper and switch off that 100-watt-high-intensity-night-vision-killer-of-a-reading-light before takeoff?
On topic and as others have said, I have never found landing lights in clouds to be an issue, other than during night approaches with a low cloud deck. The strobe can be irritating sometimes, but I'd rather be seen... And as for the passengers, if they don't like the strobes they can use their window blinds.
Sometimes night vision has it's merrits in modern airline operations, such as night visual approaches. But then again, I'd rather sacrifice my nightvision than having such a dark cockpit that I can't properly read my approach chart...
