RWR Crash Course
BAE Systems (Loral) AN/ALR-56M
C/D band (0.5-2 GHz) and E through J band (2 to 20 GHz)
Direction-finding accuracy: 15 degrees (E through J band); omnidirectional (C/D band)
Operations After boot up I indication is in middle of scope, after while it changes to WO indication in middle of
scope. After initial BIT finishes indications disappear.
System runs periodical self tests in background. Pilot can initiate manual Self Test.
POWER Button Power ups system
ALTITUDE Button Selects low alt thread threat table, L indication in middle of scope
SEARCH Button Shows search (S symbol) radars, S indication in middle of scope
ACT/PWR Lights Indicates system power and activity on scope
TGT SEP Button Separates overlapping contacts on scope
SYS TEST Button Initiates self test
UNKNOWN Button Shows unknown contacts, U symbol flashes when there is filtered out unknown contacts
MODE Button Selects priority mode
LAUNCH Button Indicates launch, initiates launch light test when pressed
HANDOFF Button Select highest priority target for composite audio, held for selection browsing
Self Test Self test shows two test screens.
After that if any fault is detected shows faults list screen and reverts to normal display with F in middle
indicating fault.
Buttons and Light Mapping Mappings are not changed from default ones.
Raytheon (Litton) AN/ALR-69(V)
C/D band (0.5-2 GHz) and E through J band (2 to 20 GHz)
Direction-finding accuracy: 15 degrees (E through J band); omnidirectional (C/D band)
Operations After boot up test patter is on scope, after while F appears in middle of scope for a moment. After initial
BIT finishes indications disappear.
System runs periodical self tests in background. Pilot can initiate manual Self Test.
POWER Button Power ups system
ALTITUDE Button Selects low alt thread threat table, L indication in middle of scope
SEARCH Button Shows search (S symbol) radars, S indication in middle of scope
ACT/PWR Lights Indicates system power and activity on scope
TGT SEP Button Separates overlapping contacts on scope
SYS TEST Button Initiates self test, if pressed and within 0.5 sec UNKNOWN button is pressed then it toggles naval mode
UNKNOWN Button Shows unknown contacts, U symbol flashes when there is filtered out unknown contacts
MODE Button Selects priority mode
LAUNCH Button Indicates launch, initiates launch light test when pressed
HANDOFF Button Select highest priority target for composite audio, held for selection browsing
Naval mode indication
Self Test Self test shows two test screens. If any fault is detected it will be indicated on second test screen with
flashing BAD text. Scope reverts to normal display with F in middle indicating fault.
Buttons and Light Mapping Mappings are not changed from default ones.
Raytheon (Litton) AN/ALR-93(V)1
C/D-band (0.5-2 GHz) and E through J band (2-20 GHz)
Direction-finding accuracy: 15 degrees (E through J band); omnidirectional (C/D band)
Operations System runs periodical self tests in background. Pilot can initiate manual Self Test.
On the top of scope are indications of CMDS mode and ECM state. On the bottom is possible ECM
interference indications (repeated on radar/TFR mfd and HUD). On the right side is ECM unavailable
indications.
POWER Button Power ups system
BIT Button Initiates self test, if fault detected FAULT light will be on
LIB SET Button Toggles normal and training libraries, normal one doesn’t contain search radars
PRIORITY Button Selects priority mode

Buttons and Light Mapping
Thales Airborne Systems Carapace
C through K band (0.5 to 40 GHz)
Direction-finding accuracy: 1 degree (C through K band);
Operations System runs periodical self tests in background. Pilot can initiate manual Self Test.
After power up, female voice informs about faults. Same voice is present on manual Self Test. Small FAIL
light indicates fault as well. This can be cleared only by power off/on cycle.
FAIL Light Indicates fault
EXP Button Separates overlapping contacts on scope, double click within 1ses initiates Self Test indicated by BIT light
PRIO Button Selects priority mode
MODE Button Toggles libraries, when AI indicator is on search radars are included
EDS AUTO Light Indicates CMDS AUTO MODE
MAN ON Light Indicates CMDS MANUAL MODE
PWR Button Power ups system
