In GA and military AC the pointer points in the correct direction.
Oh dear, here we go again.
IF you look in nearly
any GA airplane in the USA (where GA airplanes outnumber nearly all other countries, combined), you are quite unlikely to find a 'ground pointer'...only a sky pointer, to indicate bank angle.
That 'ground pointer' baloney is utter nonsense...and as we might suspect, it generally originates from... the land where refrigerators were recently discovered...the UK.
