F , S & green dot speed on A320
If i fly an A320 at F speed , how can i find the maximum allowable bank at this speed and what will be the margin with Vs ?
Same question with S speed and green dot speed
Thanks for your help

BANK ANGLE PROTECTION
Bank angle protection prevents that any major upset, or PF mishandling, causes the aircraft to be in a high-bank situation (wherein aircraft recovery is complex,due to the difficulty to properly assess such a situation and readily react). Bank
angle protection provides the PF with full authority to efficiently achieve any required roll maneuver.
The maximum achievable bank angle is plus or minus:
. 67 degrees, within the Normal Flight envelope (2.5 g level flight)
. 45 degrees, in high Speed protection (to prevent spiral dive)
further:
F : Minimum speed at which the flaps may be retracted at takeoff.
In approach, used as a target speed when the aircraft is in CONF 2 or CONF 3.
Represented by "F" on the PFD speed scale. Equal to about 1.23 VS of CONF 1 + F
S : Minimum speed at which the slats may be retracted at takeoff.
In approach, used as a target speed when the aircraft is in CONF 1.
Represented by "S" on the PFD airspeed scale.
Equal to about 1.29 VS of clean configuration.
