This update, ED-155 MOPS for lightweight flight recording systems published in July 2009, is primarily expected to ensure that the main goal of providing a low-weigh and low- cost recorder system can be achieved. The preliminary review of the current standard has identified ED155 requires additions and updates addressing provisions for testing, airborne image recordings, cockpit voice recordings, electrically powered aircraft, installations, flight data transmissions, deviations from ED-155 introduced through ETSOs/TSOs, flight crew interactions, and general updates such as, missing charts and the alignment of language with ED112B.
