Hi Ido, CMDS is a abbreviation for "Countermeasures Dispenser System". More details you found on my site under http://www.xflight.de/f16/pe_org_par_lxc_chaffflare.htm. In all modern F-16C models you find this panel. This panel replace the old ALE-40 CCU Chaff/Flare panel. Best wishes Martin "Pegasus"
