Investigating a line of thought:
Can you operate the A321 with the APU running in the air to supply a generator (in the case of one generator inop?)
The line of thinking is that if the above is possible, what are the odds a catastrophic failure of the APU causing VS and HS damage to the point of them separating or controlling the steep climb?
