| Vs1g corresponds to maximum lift coefficient i.e. Clmax. Clmax is the condition when angle of attack is maximum and load factor is equal to one. | Vs corresponds to conventional stall condition. This is the time when lift suddenly collapses and load factor is less than one. Vs is less than Vs1g.
V = 0.94 Vs1g |
Vsr stands for reference stall speed selected by manufacturer for regulatory purposes. Vsr can not be less than Vs1 so for all practical purposes Vsr is equal to Vs1g. |
