FCR 110 EXAM PREP TEST BANK VERIFIED
QUESTIONS AND CORRECT ANSWERS
●● The AH-64E uses what type of radar system?
Answer: Pulsed Wave Radar system.
●● During the periods between transmissions of a pulsed radar system,
what is the radar doing?
Answer: Listening for the echo.
●● What is the difference between a B-scope display and a C-scope
display?
Answer: B-scope displays target information in Azimuth and Range.
C-scope displays target information in Azimuth and Elevation
●● What are the three major components that make up the Longbow
Fire Control Radar (FCR)?
Answer: Mast Mounted Assembly (MMA), Radar Electronic Unit
(REU)
Radar Frequency Interferometer (RFI) Processor
●● How is the MMA cooled?
,Answer: Filtered ambient air drawn in from the surrounding
environment.
●● How are the other FCR components cooled?
Answer: The other two components that make up the FCR system are
located in the IEFABs and therefore are cooled by the ECS air.
●● Which component is zeroized when the Master Zeroize switch is
selected?
Answer: The Non-Volatile memory of the Servo Electronics LRM
within the REU.
●● Can the crew initiate another Power-on Built-In Test (PBIT) if the
FCR has timed-out under extremely cold conditions?
Answer: YES. If 13 minutes have passed, the MP will report FCR as not
operational. An additional FCR power-up may then be started.
●● What four items should the crew ensure prior to initiating an FCR
power-up sequence?
Answer: MMA must be unpinned, Verify the DMS-UTIL-BORESIGHT-
BPS, offset value is correct, Heading Tape present (EGI Alignment), and
EFAB L/R ECS supply Temperature is ≤ 63 degrees F.
●● Should both crewmembers perform the FCR Operational Check?
, Answer: If it is anticipated that both the pilot and CPG will operate the
FCR during the mission, then this task should be completed in both crew
stations.
●● How many scan sizes are available to the crew in any of the targeting
modes?
Answer: Four. Wide (W), Medium (M), Narrow (N), Zoom (Z).
●● There are three Priority Schemes resident within the REU: A, B, and
C. If B is selected, which targets are being emphasized?
Answer: Stationary ground targets only.
●● How can the PLT move the Fire Control Radar (FCR) centerline?
The CPG?
Answer: 1. Acquisition Source option (PLT - Automatic slave).
(CPG - Must press SLAVE).
2. Manually using the RHG Sight Manual Tracker (CPG only)
3. Left / Right button from the FCR page: Only available to the CM
whose selected sight is FCR
4. Executing the CUED search option in response to an RFI detect.
●● Which crewmember can make FCR centerline adjustments?
Answer: The crewmember that has the FCR as the selected sight.
