A320 Characteristic Speeds
On few A320 CEO's The characteristic speeds displayed on the PFD are computed by the Flight Augmentation Computer (FAC), according to the FMS weight data (for PFD/MCDU display consistency and accuracy purposes), and aerodynamic data as a backup.
While on some A320 CEO's
The characteristic speeds displayed on the PFD are computed by the Flight Augmentation Computer (FAC), according to aerodynamic data.
However for the A320 NEO's
The characteristic speeds displayed on the PFD are computed by the Flight Augmentation Computer (FAC), according to the FMS weight data (for PFD/MCDU display consistency and accuracy purposes). Why No Aerodynamic Data here ?
What aerodynamic data are they referring to?
Also why on the A320 NEO
In landing configurations (CONF 3 and FULL) VLS is always equal to, or greater than,VMCL.
