Utilizes the light signals automatically presented by the Vaisala TWX1200 based on customized software, as follows: • Green indicates EFMs do not exceed alarm thresholds and no lightning within 12 mi, or no EFM alarm and no lightning in past 5 min. • Green/yellow indicates one EFM at alarm threshold, or lightning strike within 12 mi.

From page 32...
... It is interesting to note that airport- and airline-defined threat and risk levels focus on the distances within which a lightning strike occurs and, at times, when the EFMs reach their alarm threshold limits. Ramp restart levels usually include a period of time during which no lightning events occur within a specified distance.
From page 33...
... In the chapters that follow, the MDA Federal team will examine these parameters, attempt to identify the essential technology that should be employed, evaluate if and how data related to lightning events and losses may be collected and reported on an industrywide basis, and establish a basis for determining a benefit/cost relationship for implementation of a lightning detection and warning system. The means by which airports and their tenants use the information developed by these technologies appears, however, to withstand standardization at this time.
