Thrust- TOGA
FMA- A FLOOR
-alpha floor is inhibited when TCAS mode is engaged on current generation A320 aircraft
Can a pilot override an automatic pull-up as a result of high speed protection activation?
No
-the override of sidestick nose down orders continues until aircraft airspeed decreases below Vmo/Mmo
How does high speed protection operate?
If Vmo/Mmo plus a predetermined factor is exceeded, the system induces a pitch up input to limit aircraft speed.
-sidestick nose down authority is progressively reduced when responding to a high speed protection recovery
What is alpha max?
The maximum angle of attack possible in normal law, indicated by the tip of the red strip on the airspeed scale.
-high AOA protection enables the PF to pull the sidestick full aft in dangerous situations

-alpha floor protection is available from lift off until the aircraft reaches 100ft RA on approach
Alpha floor protection is a function of what system?
A/THR
Requires operative A/THR to operate
-in CONF3 and CONF FULL, the threshold for Alpha floor decreases as a function of the aircraft deceleration rate
