Broadening the discussion: what opinions about the use of full or partial speed brake application? I know the recommendation is often full or nothing. Sometimes I found full caused too much rumbling; and having sat amongst nervous pax it felt un-nerving. Thus I usually used up to the rumble strip deflection. Other scenarios were when I was high approaching the GP from above I used SpdBk to give me a ROD to reach GP intercept at correct speed and ALT without any level off, and in a smooth manner. The diversity of reactions was interesting including those of 'plain wrong'. One company had an SOP for everything and there it was written all or nothing. I used to hate those straight-jacket restrictions that left no option for technique/finesse & best for the moment decisions.
