Item designator, sequence number, waypoint identifier, latitude/ longitude, and magnetic variation
of each waypoint defined in the active flight plan are transmitted with the following format: No in-
formation shall be transmitted for waypoints beyond a fence in a flight plan when the active way-
point is before the fence. Likewise, no information shall be transmitted for waypoints after the be-
ginning of a DME arc that is part of a procedure if the active waypoint is before the last waypoint
on the arc. No information shall be transmitted for waypoints prior to the last waypoint on the DME
arc if the active waypoint is after the arc.

Sequence Number
Byte 1
Bit 76543210
xlannnnn
x = undefined
nnnnn = Sequential waypoint number, Unsigned binary
a = 1 if waypoint is active
l = 1 if last waypoint of flight plan

aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa
aaaaaaaa = ASCII characters of five-character identifier
Latitude/Longitude
Latitude and longitude of waypoint. Packed, unsigned binary values for degrees, minutes, and
hundredths of minutes.

Flight Plan Data

A maximum of 32 waypoints will be transmitted.

A value of 7FH in byte 2 indicates that the waypoint
identifier is unknown and bytes 2 through 6 should
be ignored.
