Flight track of the observation flight into Beirut
The solid black line represents normal operation, whereas the red line depicts the flight track for the time period during which NAC, NIC, and SIL dropped to 0 but position information was still transmitted. The blue dashed line is an interpolation for when no position information was available.

NACP value
The first red dashed line indicates the NAV ADS-B RPTG1+2 FAULT, the second dashed red line indicates the GPS PRIMARY LOST message, and the green dashed line indicates the recovery to GPS PRIMARY.
- FIGURE 11
NIC value
The first red dashed line indicates the NAV ADS-B RPTG 1+2 FAULT, the second dashed red line indicates the GPS PRIMARY LOST message, and the green dashed line indicates the recovery to GPS PRIMARY.
- FIGURE 12
SIL value
The first red dashed line indicates the NAV ADS-B RPTG 1+2 FAULT, the second dashed red line indicates the GPS PRIMARY LOST message, and the green dashed line indicates the recovery to GPS PRIMARY.
