HEA |
Hemispheric Electronics Assembly |
|
|
DBC |
Detect Band Converter |
|
|
What component do the SDBA’s work with to send received signals to the LRU-1? |
The Detect Band Converter (DBC) |
|
|
What does the QAA (Quadrant Antenna Assembly) do? |
Receives incoming Radio Frequency (RF) emissions and passes them to the Hemispheric Electronics Assembly (HEA) |
|
|
What type of signals are captured by the SDBA? |
Low-frequency bands |
|
|
HPRT |
High-Powered Remote Transmitter |
|
|
ACM |
Advanced Countermeasures Module |
|
|
How does the LRU-1 determine which TAA to use for jamming? |
Based on the LRU-determined azimuth to the threat |
|
|
What is the function of the TAA? |
They direct and amplify the RF countermeasures back to the threat, and pass information to the LRU-3 (ACM or Modulator-receiver) |
|
|
What is the difference between active and passive ASE? |
Passive (CARC, UES, WSPS) is always running/operational in the background. Active (SIRFC, CMWS, ICMDS, LWS) has a on/off switch and is controlled by the crew. |
|
|
How do the CMWS and ICMDS subsystems work? |
They act as a sensory and reactionary group to detect and respond to IR-guided threats. |
|
|
How do EOMS work? |
They detect ultraviolet (UV) light emitted by missile exhaust, and prompts the ICMDS to respond accordingly if in the auto mode. |
|
|
How does the LWS work? |
It detects, prioritizes, and characterizes lasers engaging the aircraft as Designator, Rangefinder, or Beam-Rider threats. Then shows the threat ID and heading on the DEWD. |
|
|
How many EOMS are on the aircraft? |
5. Two on the nose, two on the tail, one on the belly. |
|
|
What does the ASE suite consist of? |
SIRFC CMWS/ICMDS AN/AVR-2B LWS AN/ALQ-144 These systems work in conjunction with each other to provide defense against MANPADS, SAM’s, AAM’s, and laser guided threats. |
|
|
What is the LRU-1? |
The receiver/processor unit |
|
|
At what altitude will the flares cause ground fires? |
400 ft AGL and lower |
|
|
What is UDM |
User Date Module (-10, pg 4-68, para (b)) |
|
|
What is DRM |
Data Recording Module (-10, pg 4-68, para (c)) |
|
|
How long can the DRM record? |
1 GB worth of memory or 20 hours in a dense signal environment |
|
|
What does the UDM do? |
Provides data storage for parameters governing SIRFC operation and response |
|
|
What does the DRM do? |
Contains storage space for recorded mission data |
|
|
What is IRCM |
Infared Countermeasures |
