The way I see it…
NVFR for all aircraft:
NVFR is not available if less than a 1/3 moon above the horizon.
Spell it out in black and white, we’ve had enough grey. In addition to the other metrological aspects that need to be considered, publish a yearly chart, NVFR is not available between the:
17th to the 22nd Jan
9th to the 15th Feb ect.
SAR / EMS
Have crews experienced enough to say no.
Have an organisation and or management big enough to allow them to say no.
Have an organisational mentality and the means to allow them to safely say yes.
If your task decision making is partly based on the amount of media coverage you’ll receive to appease your sponsors / community, get out before you hurt someone.
If you need to sell lamingtons to be able to fix the fuel gauge, get out before you hurt someone.
If it doesn’t have a 3 axis autopilot and Instrument rated pilots to fly it, at sundown, push it in the hangar.
Night over water ops (bulk carriers could be excepted) if it doesn’t have autohover capabilities and current pilots to fly it, leave it till morning.
