Pin Name Connector Pin I/O
MAIN LATERAL SUPERFLAG P4001 17 Out
MAIN VERTICAL SUPERFLAG P4001 18 Out
The output supplies not less than 500 mA on a 28 volt system and 250 mA on a 14 volt system with the
output voltage not less than (AIRCRAFT POWER –1.5 V
DC
) when the flag is to be OUT OF VIEW. The
output voltage with respect to ground is less than 0.25 V
DC
when the flag is to be IN VIEW.
