Figure 5-8 -- VISCOM.
VISCOM (FSA-97) uses push-buttons and a sequence of lights and associated aural
signals to supplement interphone circuits and to reduce the number of voice contacts
between the tower and RADAR controller. Table 5-2 shows how VISCOM can be used
at a typical RADAR and tower facility. Keep in mind that your facility may have different
procedures and that the system does not replace all voice coordination.
