Re. the stick shaker margin...
As far as memory serves me, the shaker has to be installed when the
buffet margin to stall is less than 7%. This would fit nicely with a range of shaker activation of 1,09 to 1,07 * Vs. Will see if I'm able to find an FCOM reference on it.
BOAC - your experience of not being able to achieve Vs with flight idle when decel. at 1 kt/sec. because you'd run out of up-autority - could that be the reason why no pusher is required to be installed???
