My sincere apologies to rudderrudderat for not attributing my quote in #407 to him, in 406.
PEI_3721 :

"With the lack of an airspeed display, a FBW aircraft has no backup of sensed trimmed position as with a conventional aircraft (no stick-force for trim speed error), thus it is important to look at the physical trim indication and be aware of the need to null any stick input when the desired flight path is achieved."

I was not focused on Stick force, per se, but on the lack of awareness PF had of his Pitch... To lower the NOSE, he has to overcome the springs, even though the a/c cooperates fully, (or would) in his command for descent(s)? IOW, and this sounds disrespectful of him, but is he "mistaking neutral for level?"

One assumes he was better treated in ROLL, as he seems to have sussed DIRECT LAW re: ROLL rather quickly. How is it his inputs were fundamentally on in correction angle, (only in rate did they alarm, and that soon settled out).

So, unfamiliar with "miss twitchy", he does a splendid job (DW, PJ2). (I disagree, ROLL remained a serious issue). Yet in PITCH, g controlled, he screws up quickly and chronically..... Do his actions, that result in "Level" (though climbing) emanate from sussing a "new normal" each time he lets up on Back Stick?

What are the two looking at, if they had attitude, how in GOD's name do either one not see the Nose well into blue? And what do you make of the conversation re: trend? I cannot figure what they refer to as trend, does "going up?" mean positive ROC? Or does it mean "inputting a command for climb?"

I think the allusion to ab initio (or medial) reversion is sound. He is a glider pilot, and cannot fly 330 as a Schweizer....
