Just to clarify a common error that I have seen in the GS mini story.
What you see on your PFD is not the GS mini but the IAS Target . The GS mini will never appear anywhere and is internally calculated and never shown to the pilot .
I think everyone knows PFD never shows GS even in cruise. So there's no misunderstanding on that. Yes the shifting managed IAS target on PFD makes pilot aware that GS mini is active. Ground speed(not GS mini) is always shown on ND. However on approach in HW the GS displayed on ND is roughly the GS mini. I wasn't able to locate the reference that minimum HW component for GS mini calculation is 10kts. I am thankful to FD for that. Rest of GS mini theory I am aware off.
