Important
NVIS gives a modelled indication of available light for planning. It is not a certified flight-operational decision system and does not replace an official weather briefing, risk assessment or your operator's procedures.
How do I…
- See light for a place: tap the map. The panel shows light now, the next 16 hours, the moon's direction and what contributes.
- Save a place: press and hold on the map (right-click on a computer), name it and save. Saved places appear on the map and in search.
- Plan a route: tap the route button, tap the map to add waypoints and set your speed. The panel shows light along the route at your arrival times, and the darkest point.
- Use go/no-go: Map & display → Colouring → Go / no-go, and enter your operator's limits in millilux.
- Protect night vision: tap the eye button for red-light cockpit mode, and set brightness in Map & display.
Where the data comes from
- Moon, sun and twilight: astronomical models (Krisciunas & Schaefer; Janiczek & DeYoung).
- Weather: MET Norway.
- Artificial light: NASA VIIRS night lights.
- Terrain and moon shadow: AWS Terrain Tiles.
- Aurora: NOAA SWPC.
