kilometers or nautical miles.
Line 4.-Blank.
Line 5.-ZERO is a function which permits zeroizing the
CDU or DNS memory. The specific system to zero is
accomplished by entering either CDU or DNS in the
scratchpad and pressing the ZERO VAB. Zeroizing the
CDU will FPLN dictionary storage locations to default
values. Zeroing the DNS will cause loss of HBCM data.
MODE L/L or MODE UTM is an alternate action VAB
selecting the coordinate system for display and data
entry of coordinate data.

Line 7. BACKUP ON or BACKUP OFF is an alternate
action VAB selecting DNS BACKUP mode. DSPL KM
or DSPL NM is an alternate action VAB that permits
switch of DIST and GS only from KM/KPH to NM/KTS

c. HBCM Page. The HBCM page, (fig 3-17), is used to
START and STOP the bias calibration of the DNS. The
30-second automatic reversion to NAV top level page is
disabled when HBCM is selected. Refer to paragraph
3.15.c for HBCM operating procedures. The display has
the following:

Line 1.-START is used to activate the HBCM calibration.
HBCM identifies the page. STOP is used to terminate
the calibration.
Line 2.-HBCM READY indicates the DNS is ready to
start the calibration sequence. HBCM ACTIVE, HBCM
GO, and HBCM NO-GO will also be displayed on the line
as appropriate.
Line 3.-Error messages pertinent loan HBCM condition
are displayed on this line.
Line 4.-Blank.
Line 5.-TIME XX:XX indicates elapsed time in
minutes/seconds for DNS computations of the bias
calibration. The timer will stop while the DNS is in
memory during the bias calibration.

Line 8. Scratchpad. Not used in HBCM.
d. FDLS Page. The FDLS page, (fig 3-18), is used to
initiate the On Command FDLS test function. The FDLS
page is selected by pressing the FDLS FAB. The FDLS
page has the following display.

Line 7.-TEST initiates the On Command FDLS test for
the CDU and DNS.
Line 8.Scratchpad. Not used in FDLS.
e. FPLN Page. The FPLN FAB selects the
waypoint coordinate dictionary pages. The first FPLN
page (fig 3-19), displayed when the FPLN FAB is
pressed is determined by the FLY TO selection on the
NAV top level page.

The Up/Down arrow keys can be used to scroll through
the FPLN dictionary pages. An * is shown immediately
after the storage location currently being used for FLY
TO computations and it cannot be changed until some
other location is chosen to FLY TO. The page has the
following data organization:
Line 1. - Displays the coordinate location data.
Line 2. - Displays the magnetic variation and spheroid
associated with the coordinate data above it.
Line 3. - Displays the next coordinate location data.
Line 4. - Displays the magnetic variation and spheroid
associated with the coordinate data above it.
Line 5. - Displays the next coordinate location data.
Line 6. - Displays the magnetic variation and spheroid
associated with the coordinate data above it.

Line 8. - Scratchpad for data input.
3.15.3 Data Entry Procedures. The CDU display
present position can be manually updated, waypoint
locations stored, FLY TO destination selected and other
data entries made via the CDU keyboard. Keyboard
entries appear on the scratchpad. The CDU checks the
validity of all data entered before it transfers the data to
the appropriate location on the display.
a. General Data Entry and Data Correction.
General data entry and data correction procedures follow
the example of PPOS, var, sph, and MODE UTM on
the NAV top level page.
DATA ENTRY EXAMPLE
1. Use the keyboard keys, (fig 3-11), enter the following
into the scratchpad:
12SVN32620377E12C5
NOTE
• The last character (5) is deliberately erroneous.
• Observe that each character appears on the
scratchpad, left justified, as it is entered.
2. PPOS Press. Observe that the scratchpad display
alternates between the data entered and the prompt
ERROR.
3. CLR FAB - Press. Error prompt is cleared and the
data in the scratchpad has the cursor positioned under
