by the RIO via the DEU (Figure 20-19).
1. On the DEU, select the number ofthe known waypoint
to be used as a reference.
2. On the DEU, enter the range and bearing from the
reference waypoint to the new waypoint.
3. On the DEU, press the SET pushtile and select a
waypoint number for the new waypoint.
4. Press the ENTER pushtile on the DEU. This
causes the coordinates of the new waypoint to be
computed and entered into the waypoint tile.
5. The latitude and longitude of the new waypoint
may be verified by calling the WPT DATA format
on the MFD.
20.3.6.4.6 TID Spot Hook Mode. In the spot
hook mode, coordinates are computed for a point designated
by the RIO by spot hooking on the TID based on
aircraft present position.
1. Set the sensor hand control cursor select switch to
the down (TID cursor) position.
2. On the TID control panel( FO-4), depresst heNON
ATTK and SYM ELEM pushbuttons.
3. Set the azimuth scan to i20” on the sensor control
panel (FO-4) and adjust the antenna scan center to
zero.
4. Call the WPT DATA MFD format and depress
the desired waypoint number to box the waypoint
legend.
5. On the TID control panel, set the RANGE switch
as required and the MODE switch to A/C STAB.
6. Place the sensor hand control trigger to the halfaction
position.
7. Place the TID cursor on the desired screen location
and hook by selecting full action. This causes the
latitude and longitude of the hooked position to be
computed and entered in the waypoint tile.
8. The coordinates of the hooked position can be
verified by calling the WPT DATA format.
20.3.6.5 Display Steering Modes. Selecting a
display steering mode presents the pilot with command
steering indications on the MFD and HUD. The display
steering modes include manual, data link, destination,
and tacan. The following paragraphs describe the procedures
for selecting these modes and the indications
provided. For all steering modes, the HUD should be in
the TLN mode.
20.3.6.5.1 Manual Display Steering. In the manual
display steering mode, the pilot maintains a command
magnetic course by steering the aircraft to the
command heading marker on the HUD or MFD VDI
format.
Initially the pilot selects a command course for manual
displays teeringw ith the courses electc ontrol( FO-3); this
results in the display of command course and a course
line pointer on the horizontal situation display MFD
format. The manual display steering mode is initiated
when the MAN pushbutton on the MFD VDI display
format is depressed. When this is done, the mission
computer calculates command heading by offsetting
command course for any wind drift that may be present,

steeringM. anual steeringm ode canb es electeda s follows:
1. Call the VDI MFD format.
2. Using the pilot’s CRS select knob on the
course/headingp anel (FO-3), select a course.
3. Verify the selected course value under CSEL on
the WI MFD format.
4. Depress the MAN pushbutton on the VDI format.
5. Steer aircraft to the command heading marker on
the HUD or VDI.
20.3.6.5.2 Data-Link Display Steering. In the
data-link display steering mode (Figure 20-38), the pilot
maintains a command course, commanded by external
inputs from the ASW-27C data link or ANAJRC-107
JTIDS data link, by steering the aircraft to the command
heading marker on the HUD, VDI, or HSD format. The
pilot also adjusts aircraft altitude and speed in accordance
with commanded values appearing on the VDI D/L
MFD format. The ASW-27C must be in its tactical mode
(TAC selected ontheDATALINKpane1) orJTIDS must
be in AIC and its tactical mode (JTIDS on the DATA
LINK panel).
The data-link steering mode is selected by depressing
the D/L pushbutton on the MFD VDI display format.
When this is done, the mission computer then calculates
command heading to be flown to make good the D/L
supplied command course by correcting for any wind
drift. The resulting command heading marker appears
on the MFD VDI D/L, MFD HSD D/L, and HUD D/L
formats. The D/L also supplies command altitude and
command speed that are displayed on the MFD VDI D/L
format. Command course is displayed on the MFD HSD
D/L format as a course line pointer. Figure 20-37 shows
the display formats used for data-link display steering.
Data-link steering using the ASW-27C or IJRC-107
JTIDS can be performed as follows:
1. Call the VDI and HSD display formats on the pilot
