The Software for the
control system is
specialist and can cost
alot of money to be
developed
If the computer
beaks or stops
working the software
won't work.
The software can't react to
unexpected events that
could happen
It can only do what it has
been programed to do
It won't work if there is a
power cut
People might want to
have a human expert to
do it instead although
computer control
softwares can do the job
just as well
e.g
Pilot
