As the aircraft approaches
the AR waypoint, a message
is displayed on the fourth line
of the CDU indicating the
next action the aircraft will
take (NX DME ARC). This
message is displayed thirty
seconds prior to the event
and disappears when the
action is initiated. Figure 3-
78 indicates the aircraft is fly-
ing DIRECT to D259J where
the aircraft will begin flying a
DME Arc (AR).
Figure 3-79 shows the air-
craft is within thirty seconds
of intercepting the DME Arc
at D259J.
NOTE: The naming conven-
tion for ARC waypoints is as
follows: D indicates DME.
259 indicates the radial from
the ARC center NAVAID. J
indicate the ARC distance.
i.e. A=1nm J=10nm.
Figure 3-80 shows the air-
craft is flying the DME Arc to
DILLY. (ARC 10.0) in the DIS field indicates the arc center is 10.0
NM from the aircraft’s pre-
sent position.
NOTE: Distance (DIS) dis-
played is the straight line dis-
tance from the present air-
craft position to the TO way-
point.
Estimated Time Enroute
(ETE) is the time around the
arc path to the TO waypoint.
