11.2.2 Clearing the Stormscope Page
Routinely clearing the Stormscope 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 dis-
sipating storm, discharge points appear slower and in smaller numbers.
1. While viewing the Weather Stormscope page, touch
MENU.
2. Touch the
Clear Strikes
key to clear lightning strikes.
NOTE:
The GTN displays Stormscope data with or without a heading source.
If no heading source is available, the "HDG N/A" annunciation appears in
the upper right corner of the page. When flying without a heading source,
the pilot must clear all strikes following each heading change.
11.2.3 Changing the Stormscope Display View
The Lightning page displays either a 360° or a 120° viewing angle.
1. While viewing the Weather Stormscope page, touch
MENU.
2. Touch the
360°
or
Arc
to select the display view.
