I restate my position :
IMO, the procedure for UAS in cruise phase should clearly mention to adopt the usual parameters for such phase of flight :
1.PF Maintain 2.5 degrees of pitch
2.PNF Set the thrust parameters as they are usually in CRZ
3.Wait for improvement
"Do nothing" has been my position since July 30th 2009 in a response to Stepwilk, (Post #3990), and I have consistently maintained this position in the face of considerable opposition since.

HN39's work shows the effects of a slight increase in pitch, (2.5deg increase) and while slightly destabilizing, are benign in the short term. The point has always been, when in already-stable flight, why bother? It adds work, complexity as you say, and clearly most crews ignored the drill.

In my view, the opposition is primarily because the UAS drill and checklist is indeed confusing even to trained crews and was to this point that I have continually addressed myself, even re-designing the drill. Reverting to the simplest solution is also the safest one - do nothing - maintain pitch and power, remain calm and get out the books; even the video to which you provided a link now says this, yet the BEA maintains a position now at odds with this thinking from an ordinary A330 line pilot. What is to be done?

We're arguing the same point.
