Outside both polar regions ICAO (International Civil Aviation Organization) defines daytime as that period between 1/2 hour before sunrise until 1/2 hour after sunset.I'm trying to get an official definition of 'daylight' for CASA's regulations.
It definitely wasn't 'night' but not 'day' either. It was during the sunset window.... I wonder where that 'officially' cuts off.
That is extremely useful, and extremely good news! This video was taken at 5:30 which, as it happens, is just before 30 minutes after sunset! Perfect. (note: not a great video, forgot to change video settings/exposure and was just the only place I could get to before I lost light)Outside both polar regions ICAO (International Civil Aviation Organization) defines daytime as that period between 1/2 hour before sunrise until 1/2 hour after sunset.
I think it works out to be more 10 minutes after sunset. There are charts in the AIP (Australian document) that you can work it out off. I use the Naips app. Gives you weather, notams, last light etc.I know I was certainly following all common sense rules in regards to safety but the official ones? Not so sure.
