TIPS AND TECHNIQUES
Onboard Weather Radar Overlay Usage
There are no controls of the onboard weather radar
from the map page – it is simply an on/off layer. The
map can be decluttered to remove non-essential
map content but still provide map and flight plan
graphical situational awareness and a more typical
weather radar depiction at the same time.
