Test stalled sure - but at or close to service ceiling? With a simulated full load, an imperfect trim with rearward CoG and perhaps some loss of situational awareness? (ie in a thunderstorm at night, rather than a clear day).
I fully appreciate the economics and the "tombstone imperative", however there are a growing number of the latter and what is clear from this thread is that there are few if any with any clear idea of what happens when a FBW aircraft enters coffin corner and then finds the corner. The sim is no help if its working with duff data. Passing a sim check or even playing with the sim in some rare free sim time is no bloody good if the real thing is different.
