The RFI gives the crew 360 degrees of coverage. What numeric values define the fine area?
90 degrees, with 45 degrees each side of the FCR centerline.
What is the primary difference between the fine and coarse areas of coverage?
Azimuth accuracy is much better in the fine area of coverage.
What three types of radar systems can the RFI detect?
- Pulse
- Pulse Doppler
- Continuous Wave
What is the primary function of the RFI system?
It functions primarily as an offensive system that provides NFOV target cueing for onboard and off board sights/sensors for employment of weapons.
What identifies an emitter that has been detected in the fine area of coverage of the RFI antenna array?
A triangle at the bottom center of the symbol
On what three FCR operational modes will RFI icons be displayed?
- GTM
- RMAP

10
What symbology indicates an MRFI interim solution?
A line with increasing/decreasing chevrons
What 2 configurations can MRFI be installed?
FCR (pinned) and URX
How many ASE emitters (RWR/LDS/MWS) can be displayed on the FCR page?
None
RFI detected threat/emitter symbols will not be selectable via the CAQ function on either the ASE or TSD pages when the _______ is the selected sight.
FCR
What two pages are used to enable the RFI system if it is installed on the aircraft?
FCR UTIL or WEAPON UTIL (CPG or PLT)
How can the crew select a non priority Radar Frequency Interferometer (RFI) threat to conduct a cued search on?
Reselect the cued search button and/or use the Cursor Select Function to choose an emitter.
What four functions are performed when the CUED search button is selected?
- FCR centerline slews in azimuth to the RFI #1 emitter
- FCR is placed in the proper mode, unless already there
- Sets the appropriate Scan size as determined by how the threat was detected
- Scan will be automatically initiated.
How is a manual cued search performed?
- An emitter is selected from the FCR page
- A single scan is initiated
What indication does the crew receive if an emitter has been merged?
The RFI icon will appear within the FCR footprint as the NTS
When performing an automatic CUED search utilizing the LHG, what will the FCR mode to if it is an airborne type emitter and the FCR is in the TPM mode?
ATM mode with a narrow field of view scan
In order for the crew to perform a manual cued search when the FCR is the LOS, the RFI threat emitter must be selected from the ______ page utilizing the cursor select method
FCR
What is the function of the CMWS system?
Used to detect and, in conjunction with the ICMD, counteract IR missile Threats
What component serves as the primary processing center for LWR, RWR and CMWS systems?
Aircraft Gateway Processor (AGP)
What component houses the User Data Module for CMWS?
ECU
How can the AN/AAR-57 (V) CMWS be safed in addition to selecting the SAFE/ARM button on the ASE, WPN or INIT page?
By installing the safety pin in the safety switch
Where are the HFI detects displayed on the ASE page?
Inner ring of the ASE footprint
Sights and weapons can immediately be cued to the azimuth of the HFI threat. True or False?
True
What are the two CMWS declared hostile fire threats?
Gunfire, RPG
The ASE auto store only applies to which type ASE points?
MWS geolocated points and MRFI points
Which page are ASE geo-located stored points displayed on?
TSD
In order to auto transmit a geo-located ASE point the CMDS system must be ______.
Armed
How many ASE geo-located points can be stored in the COORD file?
60, but can be indexed to 99
What do bearing lines indicate?
Pairs a geolocated ASE threat with the detecting platform at the time of detection. Altitude of detecting platform is displayed in MSL (truncated)
What capabilities are lost in an “ASE BACKUP” condition?
No ASE threat displays or audio. No inventory / fault status.
What conditions will cause the jettison feature to be inhibited?
Engaging either of the two system safeties, CMDS safety pin or weight on wheel switch (SQUAT)
What capabilities are lost in a “CMDS BYPASS” condition?
