the NAV FAB.
Following either an acceptance or rejection
of a PPOS update, the CDU resumes dis-

h. FLY TO Destination Selection.
next to the FLY TO caption on line 7 specifies which pres-
tored waypoint the DNS is to navigate to. Valid FLY TO en-
tries include values 1-19 and 0 or H. H and 0 are synony-
mous. Enter a FLY TO destination as follows:
1. Enter desired prestored waypoint value on
2. FLY TO Press. Observe that the entered value
now appears next to FLY TO and the scratchpad
is now blank.
i. UTM Coordinate Entries for Waypoint Dictio-
UTM coordinate entries, including magnetic varia-
tion and spheroid, may be entered into the waypoint coor-
dinate. The following is a typical format to be used when
entering UTM coordinates, magnetic variation and spher-
oid data in the CDU scratchpad:
Grid zone identifier
UTM 100 KM-square identifier
52.18 KM Easting within GQ
49.11 KM Northing within GQ
Spheroid identifier of CL6
A complete entry of UTM coordinates, magnetic variation
and spheroid data is not required under all circumstances.
Refer to table 3-16 for partial data entry. When an incom-
plete set of data is entered into the CDU scratchpad:
Rule 1 Order of Entry. The order of entry for UTM coordi-
nates, magnetic variation and spheroid remains the same
regardless of which parameters are or are not entered.
They are: grid zone identifier, 100 KM-square identifier,
Easting/Northing; magnetic variation; and spheroid. Data
entered into the scratchpad is always justified on the left
Rule 2 Spheroid Change. Table 3-17 shows character
string entries that are required for sph data.

Required Changes to Other Data
If data for this parameter is not entered, its value defaults to the values associated with PPOS.
The character E or W must precede numeric values for magnetic variation. Leading and trailing zeros are
not required for magnetic variation. Entering a hyphen (-) sets the magnetic variation to no computed
