b1lanc post # 356 said " The MCAS function becomes active when the airplane Angle of Attack exceeds a threshold based on airspeed and altitude. Stabilizer incremental commands are limited to 2.5 degrees and are provided at a rate of 0.27 degrees per second."
Thats about 9.3 seconds for 2.5 degrees. How many turns of the trim wheel - probably about 25 ? if as previously posted 5 degrees takes about 50 turns?
25 turns in 10 seconds = about 150 rom !!
How long to electric retrim to ' zero" or where plane" started " re trim/elevator ?
how long if power cut and revert to manual ?
The manual effort required on the trim wheel is not insignficant. I don't see how any crew could recover at low altitude with aggressive manual re-trim if they don't stay on top of the MCAS trim increments as they occur.
