ZBMAN: Maybe we are talking about different things,as I don't know the definitions for the Bus,but regarding Boeing , alpha floor,and speed limits you may find some info's in FCOM2 (737) ,command speed limiting and reversion modes:
" The AFS provides speed,pitch and thrust commands to avoid exceeding the following limit speeds: Vmo/Mmo ,wing flap placard,ldg gear placard,minimum speed.
Minimum speed is based on angle of attack and is approx 1.3 Vs for the current flap configuration.It is sensed by AOA vanes,one on either side of the fwd fuselage....
Either pitch or thrust,whichever is engaged in a speed mode ,attempts to hold the limit speed....
During some flight situations,speed control by the AFDS or A/T alone could be insufficient to prevent exceeding a limit speed.If this occurs,AFDS or A/T modes automatically revert to a more effective combination.The reversion modes are placard limit speed reversion and minimum speed reversion....
The AFS commands a speed 5 knots greater than minimum spped.Reaching a speed 5 kt greater than minimum speed reactivates normal MCP speed selection control....."
If you are talking about the fact that the AP won't intervene in case you are flying manually,with the A/T OFF...well it is true,it is not a FBW airplane...you can stall it if you wish...but only if you're manually flying...
So,are we talking about the same thing?..(limit speeds,alpha floor..)
