ASE Flashcards
Where is the AN/APR-39 Radar Warning Receiver (RWR) digital processor located in the aircraft?
Left Avionics Bay
Which component provides Radar, Laser and Missile threat audio to the crewmembers?
Communication Interface Unit (CIU)
Where are RWR, LWR and MWS detected threats displayed on the ASE and TSD pages of the Multi-Purpose Display (MPD)?
ASE threat symbols are always displayed on the inside of the ASE footprint
When will an ASE footprint be displayed on the TSD page?
When ASE threats are selected for presentation from the TSD-THRT/SHOW page and at least one threat exists for display.
Selected from show page, one threat exists for display
How may the AN/APR39A Radar Warning Receiver (RWR) be declassified?
Remove the User Data Module (UDM)
What is the purpose of the blade antenna within the RWR System?
Receives C/D band Radio Frequency (RF) energy and routes it to the digital processor.
What indication does the AN/APR-39 RWR provide if the received threat detection does not match a stored threat in the EID file?
A “U” will be displayed
How can the crew identify the system’s #1 priority ASE emitter when looking at the ASE or TSD pages?
The emitter will have a home plate symbol surrounding it.
Which component contains the classified operational software required for tactical operation of the Laser Detecting Set (LDS) / LWR?
The User Data Module (UDM)
What three threats are detected by the LDS /LWR?
Beam Rider, Designator, and Range Finder
*all laser
How many degrees of detection are provided by the LDS / LWR in elevation?
± 45
How many degrees of detection are provided by the LDS / LWR in azimuth?
360
The AN/AVR-2B Laser Detector Set (LDS) / LWR is designed to operate in conjunction with which other ASE system?
APR-39 RSDS / RWR
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, Continous 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
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, ATM
How can you differentiate between a priority emitter that is tracking/missile guidance another platform and an emitter that is signal lost, lock broken, or undetermined?
Homeplate intensity
How many RFI emitters can be displayed on the FCR, ASE and TSD pages?
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
What is the advantage of MRFI over RFI?
Passive location of threats
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
