You are right, franzl. In the case of alternate law because of air data issues it would not help to minimize the speed drop. When I was writing the example I had the critics in mind that alternate law is somehow confusing and the plane would be better off if alternate law would be skipped and the transition would go directly from normal to direct law.

Unfortunately you prooved it yourself, that it can get confusing, even when sitting in an armchair and not in the pointy end at FL350 over the ITC. And you made my other point, that some rely too much on protections without knowing what kind protections are available under what kind of law. In the A330 only ALT LAW is communicated by the ECAM, although ALT2B is latched. And i fear, that it is not en vogue to know too much details about systems and possible systems malfunctions, when flying an aircraft which performs almost all tasks on its own.
