The informal group on camera-monitor systems (CMS) produced a proposal to enable the use of CMS as an alternative to conventional mirrors (document GRSG/2011/23/Rev.1). A decision on this proposal has been pending while the Forum awaits the establishment of an ISO standard on CMS. Since the ISO standard is now in its final stages, Germany proposes to reactivate the CMS informal group in order to prepare an updated regulatory proposal for these systems.
