Put the tail strike attitude on the display
Some PFDs show a pitch limit indicator for the stall.
On the ground or close to it, the pitch limit indicator should display the tailstrike attitude.
All the engineers have to do is decide the radar altitude where the pitch limit indicator switches between tailstrike and stall modes.
And it would be a good idea to use different colors or some other change in symbology as you do want to know if the mode is off.
