REMOTE ANNUNCIATORS
A. ANNUNCIATORS
Outputs are provided to drive external annunciators to alert the pilot of system status or flight plan sequencing.
Refer to section 2 for the annunciator layout associated with a specific FMS front panel variation.
NOTE: The actual legends and colors of the remote annunciators may vary depending on the installation.
Refer to the AFMS/RFMS for details.
B. NAVIGATION FLAG
The EFIS annunciator, will be displayed under the operational or system hardware conditions listed below. At
the same time, the validity of the FMS roll steering output signal will be set to INVALID, resulting in the
disengagement of the autopilot/flight director LNAV mode.
1. OPERATIONAL CONDITIONS
a. The aircraft is airborne and the speed is below the minimum take-off speed. ACTION: None. If the
NAV flag has appeared during the take-off roll, it will disappear shortly after.
b. The active waypoint is undefined (e.g. at a route discontinuity, at the end of the route, or if no route is
loaded). The NAV flag will be accompanied by a !SELECT ACT WPT/LEG advisory message.
ACTION: Select the active waypoint.
c. During direct-to intercept navigation when engaging the LNAV autopilot mode before being on an
appropriate intercept heading. The NAV flag will be accompanied by a NOT ON INTERCEPT
HDG/TRK advisory message. ACTION: Fly to an intercept heading before re-engaging the LNAV
mode.
d. At 2 nm inbound to the FAF for a GPS approach when all conditions necessary for the approach have not
been met (e.g. no GPS integrity, loss of GPS navigation, a route discontinuity exists before the FAF, or the
aircraft is not in the approach zone). The NAV flag will be accompanied by a number of possible alert or
advisory messages, depending on the cause. ACTION: Depending on the cause, eliminate or change the
operational condition, or, if related to the GPS function, initiate a missed approach.
e. When the active route leg loaded from the navigation database is a heading or course to intercept the
next leg and the aircraft is not on the correct course or heading. The NAV flag will be accompanied by
a NOT ON INTERCEPT HDG or NOT ON INTERCEPT TRK advisory message. ACTION: Fly to the
correct intercept heading or course before re-engaging the AP/FD LNAV mode.
