Clearing The Map Page; Storm Data Display Range - Garmin 400 Series Pilot's Manual

Clearing the Map Page

Routinely clearing the Map Page of all discharge points
is a good way to determine if a storm is building or
dissipating. In a building storm discharge points reappear
faster and in larger numbers. In a dissipating storm
discharge points appear slower and in smaller numbers.
Clearing the Map Page of all discharge
points:
1) From the default Nav Page, turn the small right
knob to select the Map Page.
Press the MENU Key to display the Page

Storm Data Display Range

Storm data can be displayed on the 2000 nm zoom
scale, but the data only goes out as far as the STORMSCOPE
can report (200 nm).
North Up Mode: Since the range for Stormscope data
is 400 nm diameter total (200 nm in front and 200 nm
behind), the 500 nm range in North Up mode shows all
the data.
Track Up Mode: In the Track Up mode at the 500
nm range, a portion of Stormscope lightning data can be
behind ("aft" of) the aircraft and therefore not visible on
the Navigation Map.
Selecting a storm data display range:
From the default Nav Page, turn the small right
1)
knob to select the Map Page.
