Arearadar, there is nothing wrong with allowing the FMS/FMGC to fly a missed approach. That's why we brief exactly what "the glass" is going to do and compare it to the paper version. Allowing the autos to do it whilst being carefully monitored is probably preferable to trying to handfly the go-around when a) out of practice and b) in busy airspace with a high workload.
What concerns me here is that there is regular evidence of guys just not understanding what their aircraft is about to do and they're left hanging on by the fingernails. This is simply unacceptable from today's crews in the busy airspace we fly in.
Automation complacency? Too lazy to study? Training deficiency? Take your pick.
