RWR antenna SUB assemblies job

A

convert millimeter wave band RF signals to microwave bands (K)

it also acts as a pass through for E/J bands (since they’re already microwave)

40
Q

PTO -1
CMDS
When the cabin dispense switch is pressed, where is it sending the flare dispense command to?

A

CMWS ECU

41
Q

PTO -1
What does the JETTISON switch manual dispense?

A

All flares

42
Q

PTO -1
CHAFF LOW Advisory

A

Chaff inventory is below nine

43
Q

PTO -1
FLARE LOW Advisory

A

Flare inventory is below nine

44
Q

PTO - 1
What does BYPASS MODE in the CMDS/CMWS Operation do?

A

Bypasses CMWS ECU. The sequencers ignore any commands from the CMWS ECU and independently monitor the cyclic countermeasures mode switch and cabin switches for commands.
Dispensing is now controlled by the programs that were uploaded to the sequencers from the UDM/RDM by the CMWS ECU during systems initialization. (Defaults)
Used in the event of a system failure.
