"I'm curious why the ND is in the PLAN MODE and the standby altitude indicates 36880 level in cruise, presumably at 370 (maybe that's within tolerance for the STBY, don't recall). Turbulence ? Hand flown ?"

Afraid I know so little about the B737NG that I had foolishly mistaken that S/B flight display for the PFD... But, apart from the ND being in PLAN mode, it looks like a routine cruise regime, including the engine parameters.

Apart from the AoA, the parameter that I don't understand on the DFDAU display is the STAB angle of 5.8, which taken on face value would probably be 5.8 degrees nose-up trim (i.e., minus 5.8 degrees aerodynamically). That's more than double what I would have expected at cruise speed (clean).
