Salute!
No , infrequent.
Many pilots are not saying MCAS does not honor pilot trim cmds from the wheel. And further....
The data traces clearly show all the pilot trim cmds and they are correlated one for one with Hal stopping and waiting 5 seconds and re-applying nose down trim. The AoA rules the MCAS, not STS system.
Something different happened about 30 seconds before the dive. Power application, diversion of control forces, 4+ degrees of stab position. Would be nice to see gee and best of all, the cvr. Maybe the trim wheel has been recorded, and that could explain a few things, as well.
Gums sends...
