However, part 23/25 certification states a maximum permissible wing drop and lateral and directional control may be used to contain it.
Whilst I agree that is what the regulations say, I can't say I'm a great fan of seeing the skill of a highly experienced handling test pilot used to create a beneficial outcome that would not be seen if the event was encountered by an average line pilot, with their likely training and reaction times.
There have been issues in the past with commercial operation when recovery at stall warning did not stress the need to reduce AoA and had procedures that were akin to a wind shear recovery or a go-around.
Indeed, exacerbated, as I indicated above, by the use of training aeroplanes with exceptionally benign handling characteristics, not necessarily representative of the characteristics of aeroplanes that trainee pilots may fly later.
