Flight Display

10.30.3
The FPV symbol is displayed in two brightness levels. The FPV symbol is
displayed dim when either the flight director or a TCAS resolution advisory is
displayed. The FPV symbol is displayed bright when the flight director is off and
there is no TCAS resolution advisory displayed.
Instrument Landing System Indications
ILS glideslope and localizer deviation, frequency/identification, DME, course,
and marker beacon indications are provided.
The approach reference information appears above and to the left of the attitude
display. The ILS station identification or frequency, course, and (if available)
DME are displayed.
The marker beacon indication (OM – outer marker, IM – inner marker, or MM –
middle marker) is displayed in the upper right corner of the attitude display area.
The glideslope pointer and scale appear on the right side of the attitude indication
when a valid signal is received. At low radio altitudes with autopilot engaged the
scale turns amber and the pointer flashes to indicate an excessive glideslope
deviation. The pointer is not displayed when the glideslope signal is unusable or
when the track and the front course on the mode control panel differ by more than
90 degrees (backcourse).
The localizer pointer and scale appear at the bottom of the attitude indication when
a valid signal is received. When the course deviation is slightly more than ½ dot,
the localizer mode is engaged and track is within 5 degrees of the MCP selected
course, the scale automatically expands. At low radio altitudes with autopilot
engaged the scale turns amber and the pointer flashes to indicate excessive
deviation. Below 1,000 feet AGL with LNAV engaged and LOC armed, the
localizer scale turns amber and the pointer flashes if the localizer is not captured.
Each pilot’s deviation alerting system self-tests upon becoming armed at 1500 feet
radio altitude. This self-test generates a two second LOC and G/S deviation
alerting display on each attitude indicator.
Below 2500 feet radio altitude with the localizer pointer in view, a rising runway
symbol comes into view. The symbol provides lateral guidance. At 200 feet radio
altitude, the symbol rises toward the airplane symbol.
Approach Minimums
The selected radio altitude or barometric approach minimums are set on the EFIS
control panel. They are displayed near the bottom left of the altitude display.
