NAV GNSS 1(2) FAULT
\n<\/strong>&

\n<\/strong>NAV GNSS 1(2) REJECTED BY IRs

\n<\/strong>NAV GNSS 1+2 REJECTED BY IRs<\/strong><\/p>\n

What’s the difference between REJECTED BY IRs and FAULT?\u00a0 The INOP SYS of GNSS 1+2 REJECTED BY IRs is less than GNSS 1+2 FAULT. For example, can we make GLS AUTOLAND or FLS even when GNSS 1+2 REJECTED BY IRs?<\/p>\n

A: <\/strong><\/p>\n

The alert NAV GNSS 1(2) FAULT is triggered when the GNSS partition of MMR 1(2) is detected faulty by ADIRS and declared faulty or lost by the MMR. The NAV GNSS 1(2) REJECTED BY IRs alert warns that the GNSS partition of MMR 1(2) is detected faulty by ADIRS but not declared faulty or lost by MMR. The same principle applies for NAV GNSS 1+2 FAULT and NAV GNSS 1+2 REJECTED BY IRs.<\/p>\n

When one or both GNSS are rejected by IRs, it means that only the path between IRs and GNSS is lost. Therefore, GNSS are still operative and continue exchanging data with the other systems. In this case, the INOP SYS list is limited compared to the one displayed in case of GNSS fault.<\/p>\n

In particular, when NAV GNSS 1+2 REJECTED BY IRs is triggered, the GLS autoland and FLS capabilities remain available.<\/p>\n","protected":false},"excerpt":{"rendered":"
