Dear PJW and Peter

May I ask a silly question about AWS? I was wondering why we allow the AWS to be intervened by human? Any benefit for it?
If human cannot intervene AWS, then it would be safer, right? and it will not have a SPAD, unlike TPWS.

Thanks in advance for helping me out.

Best regards
Arnut
