INDEX
If heading input is lost, strikes and/or cells must be cleared manually after the execution of each turn
(Figure 6-67). This is to ensure that the strike and/or cell positions are depicted accurately in relation to the
nose of the aircraft.
Manually clearing Stormscope data on the Navigation Map:
1) Press the MENU Key.
2) Select ‘Clear Stormscope Lightning’ (Figure 6-67).
3) Press the ENT Key.

ZOOM RANGE ON THE NAVIGATION MAP
Stormscope lightning data can be displayed up to 800 nm zoom range (in North Up orientation) on the
Navigation Map Page. However, in Track Up orientation at the 500 nm range, a portion of Stormscope lightning
data can be behind the aircraft and therefore not visible on the Navigation Map. 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 orientation
shows all the data.
At a map range of less than 25 nm, Stormscope lightning data is not displayed, but can still be present. The
presence of Stormscope lightning data is indicated by the annunciation ‘LTNG < 25 nm’ in the upper right
corner (Figure 6-68).
