After reviewing the thread and other web descriptions of MCAS, it is not clear (to me) what effect the flap configuration has on an erroneous AoA input.

The most recent AD does not refer to flap (nor thrust or any other Air data inputs); thus ‘failed’ MCAS nose down trim could be active immediately after take off.
Is the flap configuration an input which could influence the conditions of the failure?
Is the lack of reference in the AD an oversight; or have I misread, or misunderstood some important aspect?

Is there any definitive description of the ‘MCAS’, purpose and operation, either from the manufacturer or the FAA?

Good points Jim #70
