Itīs been three years since Iīve flown the Mad Dog, but in my old books Iīve found a table for the rudder limits (AOM part 2 chapter 9 "flight controls" page 3 ). I tried to scan the page and post it here, but somehow I canīt put attachments to my post. So here it goes:
Rudder travel unrestricted light
MD 81/82 off above max. 181 KIAS
on below min. 148 KIAS
MD 87 off above max. 192 KIAS
on below min. 159 KIAS
MD 83 off above max. 201 KIAS
on below min. 165 KIAS
Hope this helps.
