"In that case, I wonder how accurate the stick shaker would be with taped over static ports ?"
Sorry, Mike, I'll have to leave this one to the physicists and design engineers to comment on (I only fix 'em)
Also, Boeing probably keep the finer details of air data signal processing in the Stall Warning Computer to themselves.
A good engineer/aircraft cleaner should leave a long, red (or other highly visible colour) streamer attached to any temporary pitot static system cover.
Regards.
