Spitfire II Pilot's Notes on diving: (http://www.scribd.com/doc/4598146/Pi...lin-XII-Engine)

DIVING
21. The Maximum permissible diving speed is 450 m.p.h. A.S.I.
Note the following:

(iii) The aeroplane should be trimmed in the dive, i.e. the trimming tab control should be set to give no load on the elevator. This will lessen the possibility of excessive "g" being induced in easing out of the dive particularly if the pilot should ease his hold on the stick owing to "blacking out" or any other reasons. No difficulty in easing out of the dive will be experienced even if the aircraft is trimmed in the dive as the elevator control is comparatively light and recovery from the dive is not resisted by excessive stability in pitch. Elevator tabs may be used, very carefully, as in para. 14.
