The "Something Wicked" F117 (Vega 31) shot down during the Kosovo war can be considered as a result of a "control design fail"?
The intensity of the missile proximity fuse detonation made the system fail.
And what´s the threshold?
OK, cute, but not relevant to AF447.
What´s the threshold of a WX condition to an a/c?
Not sure quite what you are implying. Why have an aircraft that could handle the worst weather it might encounter enroute except the flight control system can't hack it (but could if it was told how to)?
The System faced an UAS (like other 37 cases since 2003). The System simply cannot afford loose some very basic inputs, like air speed.
UAS is an
assumed causal factor by BEA but not yet proven. Depending on what came first in the loss of AF447, it might still be the
result of a departure, not the cause. But I will absolutely agree that they need a better system to provide airspeed. The control design is too dependent on it as presently structured.
