The quick development of the Electronic Flight Bags (EFBs) use over the last years was such that they became a very common and important tool for flight operations and have replaced paper in most cockpits. Increasingly present, EFBs also feature more and more advanced functions that depart from the simple replacement of paper while offering new possibilities to enhance flight operations and information available to the flight crew. Consequently, EFB applications and their hosted functions become more complex to evaluate and to approve for use in operations by the national aviation authorities. This industry standard provides a systematic and comprehensive means to address the design, development, evaluation and validation of the EFB applications proportionally to the safety risk of their intended use in flight operations.
