Boeing is working on modifications to a controversial software linked to both crashes, the maneuvring augmentation characteristics system, MCAS. Boeing chief executive Dennis Muilenburg tweeted on April 16 that the company was making steady progress towards certification of the software and related training changes. The company had just completed the last official engineering test flight of the updated software prior to a certification flight with the FAA. Muilenburg said this had involved 120 MAX flights totalling more than 203 hours of flying time. He had completed a demonstration flight and had seen first hand the software in its final form “operating as designed across a range of flight conditions”. However, potential differences emerged between Canada and the US on whether training for the new software should be in a simulator or be computer-based.
