6：Bearing, degrees true
7：Bearing, degrees true
8：Bearing, degrees magnetic
9：Bearing, degrees magnetic
10：Distance, nautical miles
11：Distance, nautical miles
12：Waypoint ID
13：Mode indicator (see Note)
NOTE Positioning system mode indicator:
A = Autonomous mode;
D = Differential mode;
S = Simulator mode;
N = Data not valid.
The mode indicator field should not be a null field.

1：Status (see Note 4): A = data valid
2：Cross track error (see Note 2), nautical miles
3：Direction to steer L/R
4：Origin waypoint ID
5：Destination waypoint ID
6：Destination waypoint latitude, N/S
7：Destination waypoint latitude, N/S
8：Destination waypoint longitude, E/W
9：Destination waypoint longitude, E/W
10：Range to destination, nautical miles (see Note 1)
11：Bearing to destination, degreestrue
12：Destination closing velocity, knots
13：Arrival status
A = arrival circle, entered or
perpendicular passed
V = not entered or passed
14：Mode indicator (see Notes 3 and 4)
NOTE 1 If range to destination exceeds 999,9 nautical miles, display 999,9.
NOTE 2 If cross track error exceeds 9,99 nautical miles, display 9,99.
NOTE 3 Positioning system mode indicator:
A = Autonomous mode;
D = Differential mode;
S = Simulator mode;
N = Data not valid.
NOTE 4 The positioning system mode indicator field supplements the status field (field No. 1) which should be set
to V = invalid for all values of Mode indicator except for A = Autonomous and D = Differential. The positioning system
mode indicator and status fields should not be null fields.
