Speedwinner
Vls is not g dependant it varies with weight. Valpha prot and Valpha max are current AOA measured by two active valid AOA probes and averaged. It is converted to speed and shown on PFD. They are load factor sensitive so vary with load factor. So when you bank or increase the load factor the alphaprot (at high altitude) may catch up to vls and cover the Vls. The difference between current speed and Valphaprot (or Valphamax) represents the actual margin between alpha prot and alpha max.
