The high rate is always a problem. When receiving a level off RA , you disconnect A/P and if you do this close to the selected altitude your chances or overshooting a few 100 feet is very high .
This is one of the cases where the incident is in fact caused by having TCAS . No TCAS and the A300 would have most probably leveled off at FL210 as cleared by ATC and (hopefully) selected in the FD by the crew . The RA changed that a bit . But TCAS assume the intruder will not level off , In fact it is there to cover you for the " most probably" and the "hopefully" which is a good thing.
We just have to live with those once in a while.
Doesn't that depend entirely on the crew's "personality" when flying ? For instance, they could "overreact" and push hard on their stick, get a +0.25G in the cabin, and level off almost instantly, or they could push very gently, more gently than the AP, and overshoot.
But it should really depend on how they manual-fly, shouldn't it ?
