waypoints, set the CDU to MODE UTM and fol-
low the example.

p. Target Storage.
The DNS target store function
operates similarly to the AN/ASN-128 target function. To
perform this function, press the STR FAB. This will store
DNS PPOS coordinate data, magnetic variation and
spheroid data values into the waypoint number desig-
nated on line 7 of the NAV top level present position page.
The TGT STR number automatically increments to the
next higher number after each storage function until it
reached 19, then the counter will reset to 16.
For example:
TGT 17 specified that at the time the STR
FAB was pressed, the instantaneous DNS PPOS data
was stored into waypoint number 17.

FDLS message to be displayed on line 7 of the NAV top
level present position page do the following:
