Figure 2-97. HUD Symbology Available on A/A Formats (Sheet 2 of 2)
IRST modes are indicated on the HUD via alphanumerics.
The IRST mode alphanumerics are removed
when the IRST is failed. The IRST alphanumerics are
as follows:
1. Cooldown (COOL)
2. Hot IR (HOTIR)
3. Pilot automatic lock-on (PAL)
4. Pilot lock-on mode (PLM)
5. Single-target track (STT)
6. Standby (STBY)
7. Track while scan automatic (TWSA)
8. Track while scan manual (TWSM).

selection on the PDCP or selection of an air-to-ground
weapon places the A/G basic format on the HUD (Figures
2-98 and 2-99). The A/G basic format can display
waypoint and tacan information. A/G DECLUTTER
and ANLG and DGTL displays are similar to A/A formats.
Refer to NAVAIR 01-FI4AAD-IA.
2.33.8.4 Overlay Symbology. Symbology (Figure
2-100) may be overlaid on displayed HUD formats when
additional information is required. These include RECON,
TWS, and IRST TWS.
RECON, used with the TARPS pod, is selected as an
overlay from the MFD RECON formats. This overlay
adds the RECON command heading marker, command
ground-track line, RECON steering symbol, targetdesignator
hexagon, and camera selection legend.
Radar track while scan adds up to four radar target
diamonds that indicate the four closest targets. Size of
the symbols indicates relative proximity (i.e., the largest
is the closest). The four symbols are of preset sizes, not
scaled to reflect actual distances.
The infrared search and tracking system TWS adds
up to four triangular IRST symbols to existing formats.
Unlike TWS, these symbols are all the same size. Both
IRST and TWS symbols are added automatically when
a target is being tracked.
2.33.8.5 Manual Reticle. If the mission computer
loses communication with both DPs, the DP driving the
HUD provides a manual reticle format (Figure 2-101)
NAVAIR 01.F14AAD-1
allowing gun aiming by displaying the A/A gun/backup
mode reticle. The reticle depression angle, adjusted by
the ELEV LEAD knob on the PDCP, is shown in the
lower right corner of the HUD along with the MAN
gun-mode indication.
2.33.9 MFD Formats. Initial turn on or a cold start
(defined as a system reset or a power outage to the MCS
ofat least3 00 milliseconds) causesth e following default
formats to be displayed: VDI TLN basic on MFDI,
OBC basic on MFD2, and OWN A/C basic on MFD3.
The actual format displayed on MFD3 depends on the
navigation mode selected and the conditions existing at
the time. If the NAV MODE switch is at OFF, the OWN
A/C basic format is displayed.
MFD3 may also act as a controller of the DEU in that,
when certain formats are being displayed on MFD3, the
DEU is commanded to display corresponding slaved
formats. Refer to Figure 2-102 for a listing of
MFD3/DEU slaved control conditions.
With the exception of high-priority formats (ECM
