The mention made was well for a loss of indicated altitude (under reading) and not a loss of altitude display.
So many questions on the FD during the presentation ...
So little answers ...
And so little in the report too ...
It has been central in the BEA work ... but they won't share the details.
BTW where is the FD/AP Vertical Mode Trace ... ???
