Module 12. Helicopter aerodynamics, structures and systems
The stalling speed of an helicopter blade
•  does not change.
•  is increased when the helicopter is heavier.
•  is increased when the helicopter is lighter.

YukonGhetto asking:
•  Blade stall is more likely when the HC is heavier. Does that not mean that the stalling speed of the blade is increased when the HC is lighter and will stall at a lower speed when the HC is heavier? Just getting ready for my A3 and this is confusing me!
