securing both the LRU's and brackets. Every vehicle/platform contains one
Master Control Station (MCS), a number of Full Function Crew Stations
(FFCS), and a Permanent Magnet Loudspeaker (LS). Depending upon the
vehicle/platform VIS is being installed in, it may also contain Radio
Interface Terminal(s) (RIT) and Monitor Only Station(s) (MOS).
