Study Notes
FCR Target Symbols
- Up to 16 FCR target symbols are displayed on the FCR page for a given scan.
- Symbols represent the highest priority targets detected and classified for that scan.
- Symbols are displayed in yellow by type target, type of anticipated RF missile launch (LOAL or LOBL), and a condition of moving or stationary.
Target Symbols Display
- Moving target symbols become stale after 5 seconds.
- Stationary target symbols become stale after 30 seconds.
- Low priority targets are displayed in partial intensity yellow on the TSD page as a half-size icon.
FCR Priority Schemes
- Three priority schemes are used by the FCR (options A, B, and C).
- Priority scheme A emphasizes airborne and stationary ground targets.
- Priority scheme B emphasizes stationary ground targets.
- Priority scheme C emphasizes airborne and moving ground targets.
FCR Target Data
- FCR target data is prioritized by the FCR and used to direct the selected weapon against targets and to enhance situational awareness.
- The aircraft is capable of displaying up to 256 FCR target icons on the TSD page.
Sensor Selection
- The FOV should be either Narrow or Zoom when designating a target.
- Narrow and Zoom are the only FOVs that are boresighted.
LRFD
- The LRFD has a maximum value of 9999m.
- The asterisk is present when the laser is firing and the WP (MP for AH-64E) is receiving valid range data from the laser rangefinder/designator.
FCR Operations
- The FCR will provide reliable data while maneuvering up to 20° in roll and +20° to -15° in pitch.
- Flight outside these parameters may result in degraded FCR performance.
FCR Modes
- The FCR is employed in three of the four available modes to perform targeting.
- Ground targeting is accomplished using GTM and RMAP.
- Air targeting is accomplished by using ATM.
RFI Symbols
- RFI symbols representing RFI detected emitters are displayed on the periphery of the radar scan sector to indicate the direction to the detected threat.
- Up to 10 RFI symbols can be displayed.
- RFI symbols are displayed in full intensity during the period when the RFI emitters are emitting plus 30 seconds after emitters cease transmissions.
CUED Search Button
- The CUED search button is used to quickly orient the FCR to a RFI detected radar emitter to conduct a scan.
- Selecting the cued search button is a quick way to mode, point, size, and initiate the FCR for a scan.
Display of Targets
- The PSP sends the target data to the display processor to display information on the FCR page, TSD, and HDU if C-SCP is selected.
- Display locations and quantities are:
- TSD: NAV phase – Up to 16 prioritized targets
- TSD: ATK phase – Up to 256 targets
- FCR Page: Up to 16 prioritized targets
- HDU: If C-SCP is selected, up to 16 prioritized targets
