PFD Rose Format
The full compass ROSE format represents the 360° compass card with 45° index marks, overlaid selectable navaids, bearing and course pointers. The indications include course pointers, lateral deviation bar, lateral deviation scale and to/from indicators.
PPOS Present Position Navigation Map
PPOS, displayed on both PFD and MFD, is a present position navigational map with a heading display window. The PPOS map displays geographically positioned FMS symbols, representing active flight plans, airports, waypoints, intersections, NDBs, VORs, VORTACs and holding patterns.
The following overlays can be superimposed on the PPOS map: weather radar, lightning, terrain and TCAS.
The active NAV source, FMS1/FMS2, remains annunciated on the left side of the map, to identify the source of the map. If any navigation source other than FMS1/FMS2 is selected, or if an automatic transition of PRESELECT NAV source to active source occurs during a NAV to NAV capture, the FMS flight plan information will be removed and replaced by the course/deviation display.
FMS PLAN Map
The FMS PLAN MAP format is used during the initial flight plan setup, or to plan a deviation from the flight plan route.
This format always shows true north at the top of the display. Modified FMS flight plan information can be verified by selecting the up or down scroll keys on the FMS CDU. The weather radar, terrain and TCAS cannot be overlaid onto the (static) PLAN map.
PLAN map and TEXT displays are MAP features exclusive to the MFD, and are not available on the PFD navigation field.
