Have a think about this from a fire management perspective.
Are we talking about bucketing or monitoring a fire at night. Worth doing on the urban interface with lots of cultural lighting if houses blah blah at risk. Probably reasonably safe in the Lane Cove National Park in the middle of Sydney or at the recent fire at Enoggera in Brisbane surrounded by cultural lighting.
Something out of Bulga into Wollemi National Park. No cultural lighting and often cloud forming at night in the smoke. Forget it. Better ways of monitoring by fixed wing anyway.
Remember the ground troops don't like working fires at night either.
Most experienced Met's will tell you that vis in smoke is a stab in the dark anyway. For those that have not seen it vis can go from CAVOK to 100 metres or less in an instant.
Why would you you be out attacking the middle of a national park on a dark night?????
Ogsplash where are you. your thoughts??
