Hi OK465,
Thanks for your detailed, hands-on sim reports. Just to pick up on one:
"The jam engine accels or decels seem to cause the largest AOA variations (both below and above depending) from the stabilized alphamax value, but still resulting in no more than a couple knots above Valphamax on the thrust increases or dipping a couple of knots into the red band on rapid thrust reductions before the available FCS actuated elevator (and AOA control) gets things back under control at Valphamax."
You describe the IAS as varying above or below Valpha-max by "no more than a couple of knots". But did you notice whether the Valpha-max itself remains constant, or if it varies slightly with load factor and/or FPA?
Quote from CONF_iture:
"For the PF to maintain full back stick for a while is not of all comfort. If he wants to concentrate outside, I find it practicable for the PNF to stay inside and manage thrust versus v/s."
So, starting from straight-and-level at alpha-max, let's look at the control of the flight path:
the PF controls bank and can initiate a descent (intentionally or accidentally), but not reverse it;
the PNF controls climb and descent, provided the PF doesn't interfere.
Interesting work-share arrangement, 100ft above the ground. I suppose it might have worked.
