ligne de vol, acceleration verticale
Like you, I was puzzled by the fact that, in contrast with the rest of the report, that last bullet of the Findings is so poorly worded. Was it hastily re-edited at the last minute? I guess it was probably meant to say something like:
- based on that fact, and on visual examination of various elements, it would appear that the airplane was not destroyed in flight, that it was essentially aligned with its flight path at impact, and that impact forces resulted in high values of acceleration along the airplane’s vertical axis.
I researched Wikipedia for "en ligne de vol" and got 4 rsults, including the BEA Interim Report. The best I can make of those results is "flight attitude" or "aligned with flight path"
