"---think about it why no stall during the top of a loop or the summit of a hammerhead [near zero on the ASI sometimes]" ?

No Takers? OK then,

---because, the flightpath of the aeroplane has been adjusted to 'keep up' with the relative wind'---so at no time is the stall AoA achieved

...which also results in the airplane being in a near-zero-G (ballistic) state, thus wing loading is very low.

In a hammerhead, the wingtip on the inside of the turn may actually be flying backwards, if only for a second.

Dan Winterland and Barit1 that's the other correct way to see it---now the COMPLETE perspective has been elucidate---I love discussing the stall !

Fangio: Thank you very much for the info- interesting

the discussion much appreciated Gentlemen!
