higher service level, provides more data (such as storm
cell movement and Datalink lightning).
u TWXCELL - If Wx Ovly is set to TWXCELL,
the EX5000 displays thunderstorm cells
detected by the TWX670, using colors
(Table 2.1) to indicate levels of storm intensity. For
example, Figure 2.2 shows an aircraft located at the edge
of intense thunderstorm activity. In this instance, the
aircraft must be flown away from the thunderstorm. The
TWX670 detects and measures lightning strike energy
and generates cell data that the EX5000 displays in
!
For Datalink RADAR, small areas of high-intensity datalink
radar data might not be displayed on the EX5000 at high
range settings. Instead, larger areas of surrounding lower-
intensity returns might obstruct indications of severe
precipitation at Map ranges higher than 250 nm. Avoid using
Map ranges greater than 250 nm when RADAR echoes are
shown in the vicinity of the aircraft.
