For the sake of within-subject correlation, a linear mixed model was used to detect the differences of variables including ACD, ACV, ACAW, IOP, and vault between time points.
Mean ACV was 193.28 [+ or -] 29.15 [mm.sub.3], mean ACD was 3.15 [+ or -] 0.23 mm, and mean ACAW was 36.51 [+ or -] 6.54 degree before operation; they, respectively, decreased to 112.48 [+ or -] 17.01 [mm.sup.3], 2.99 [+ or -] 0.23 mm, and 22.54 [+ or -] 5.27 degree at 2 years (p = 0.0008, 0.008, and 0.0003, resp.).
No significant relationship was found between postoperative and preoperative ACAW (r = 0.21, p = 0.10).

As the starburst sound was heard by all crewmembers, it was odd not to hear from one of the most opinionated members of the crew, our chatty copilot, until the radar operator (RO) noted on the advisory caution and warning system (ACAWS
) readout that we were seeing multiple "FC ACO-CP" and "FC CP-ACO" messages.
The advisory, caution, and warning system (ACAWS) on head-down display (HDD) No.
However, rather than prepare for an engine shutdown, my copilot casually pressed the annunciator switch light to silence the warning, as the crew chief nonchalantly noted that the ACAWS was erroneous.
We do this because pitch-control-unit (PCU) sensor faults are a common issue that routinely result in a "LO PITCH STOP FAIL" ACAWS. If we always ensure a good overspeed test before each takeoff, then we never have to shut down an engine for this ACAWS according to the interim flight clearance.
