 Path deviation band  MAP,  Path deviation band is symmetric 

 (M)  MAP CTR  about the pointer and represents vertical RNP. 

 Position trend  MAP,  Predicts position at the end of 30, 

 vector (W) (dashed  MAP CTR  60, and 90 second intervals. Each 

 line)  segment represents 30 seconds. Based on bank angle and ground speed. Selected range determines the number of segments displayed. For range: . > 20 NM, 3 segments . = 20 NM, 2 segments . < = 10 NM, 1 segment. 
ABCDE  Active waypoint identifier (M)  MAP, MAP CTR, PLN  Indicates the active flight plan waypoint, the next waypoint on the route of flight. 
124NM  Active waypoint distance (W)  MAP, MAP CTR, PLN  Distance to the active waypoint. 
0835.4z  Active waypoint ETA (W)  MAP, MAP CTR, PLN  Indicates FMS–calculated ETA at the active waypoint. 
AMBOY  Waypoint: active (M), modified (W), inactive (C)  MAP, MAP CTR, PLN  Active– represents the waypoint the airplane is currently navigating to. Modified – represents the waypoints on the active route that are being modified. Inactive – represents the waypoints on the active route.

MLF  Off route waypoint (C)  MAP, MAP CTR, PLN  When the EFIS control panel WPT map switch is selected on, waypoints not on the selected route are displayed, for ranges of 5, 10, 20, or 40 NM. 
PARBY KILMR AMBOY  Flight plan route: active (M), modified (W), inactive (C), offset (M)  MAP, MAP CTR, PLN  The active route is displayed with a continuous line (M) between waypoints. Active route modifications are displayed with short dashes (W) between waypoints. Inactive routes are displayed with long dashes between waypoints. An offset route, selected through the FMC, is displayed with a dot–dash line (M) parallel to the active route. 
12000 KILMR 0835Z  Route data: active (M), inactive (W)  MAP, MAP CTR, PLN  When the EFIS control panel DATA switch is selected on, entered or procedural altitude and ETAs for route waypoints are displayed. 

 Holding pattern:  MAP,  A holding pattern appears when 

 active (M),  MAP CTR,  in the flight plan. 

 modified  (W), inactive (C)  PLN  The holding pattern appears as a fixed size if the selected range is greater than 80 NM. A scaled representation of the holding pattern is displayed when the selected range is 80 NM or less and the airplane is within 3 minutes of the holding fix. 
Altitude range arc  MAP,  Based on vertical speed and 

 (G)  MAP CTR  groundspeed, indicates the approximate map position where the MCP altitude will be reached.
