1.2.2.4 CMDS panel
The CMDS panel is part of the EWS suite and mainly manages all
countermeasures. It is used in conjunction with the CMS switch on the
sidestick (see stick section on the right console).
The RWR and JMR switches are two state toggle switches that control
automatic dispensing of chaff and flares. The RWR switch must be ON
for the SEMI and AUTO modes to function. The JMR switch needs to be
ON for the EWS to be able to release countermeasures coordinated with
the use of the Jammer pod.
The MWS switch is not implemented in the USAF latest block inventory jets and this is therefore not
implemented in BMS.
The panel provides four categories of expendables, only two are supported in the F-16. They are on
the right side of the panel and labelled CH for chaff and FL for flares. Category 01 & 02 are not
implemented and can remain OFF. When the switch is OFF the display above remains blank.
Needless to say both the CH and FL switches need to be ON for chaff and flares to be released. The
above indicator displays the number of expendables remaining and when bingo level is reached (set
through the DTC or UFC) LO is displayed with the number remaining. When a category is exhausted 0
is displayed.
The MODE knob selects the CMDS operating mode: OFF, STBY, MAN, SEMI, AUTO and BYP.
Depending on the mode selected the countermeasures released correspond to the selected program
(position of the PRGM knob).
OFF - the CMDS is not powered and countermeasures cannot be released.
STBY - the release parameters and programming can be manually changed using the UFC. It is the
only mode allowing reprogramming. The CMDS cannot release countermeasures in this mode.
MAN - only programs 1 to 5 can be released manually by the pilot by using the CMS on the sidestick.
CMS forward releases whatever program is selected (1 to 4) through the PRGM knob. Program 5 can
also be released with the slap switch on the left side panel.
SEMI - release is not automatic but the EWS will prompt the pilot through the VMS
(“COUNTER”)
whenever the system feels countermeasures should be employed. The pilot then can give consent to
release by depressing CMS aft. The selected program will be then released once. If the threat persists
the EWS will prompt for consent again (
“COUNTER”). Consent must be given each time. Please note
that for the SEMI mode to work the RWR switch on the CMDS panel needs to be ON.
AUTO - Consent must be given once (CMS aft) and is assumed until it is explicitly cancelled with a
CMS right. Deployment of countermeasures is thus automatic and can deplete your stores very fast
depending on the program selected.
BYP - is a Bypass mode and is used when the CMDS fails. BYP allows the pilot to release one chaff &
one flare only at each CMS forward command. BYP is always manual; no SEMI or AUTO functions
are active while in BYP.
The PRGM knob allows the pilot to select one of the 4 pre-programmed countermeasure sequences.
When CMS forward is depressed the selected program is activated. There are a total of 6 programs
but only 1
– 4 can be selected through the PRGM knob. PRG 5 is always activated by the slap switch
on the left sidewall and PRG 6 is always activated by depressing CMS left. All 6 programs can be
programmed through DTC, or the UFC whenever the CMDS mode in is STBY.
The BIT position is the CMDS self-test and is not implemented in BMS.
