</div>The entire purpose of the inspection is to certify that various parts,<br>
including instruments and controls in the cockpit, are functional. The<br>
only way to not notice the bear is to have not done the inspection, in<br>
which case you have no business signing the certificate. There is no<br>
point in automating the bear check because your primary duty of<br>
inspecting the instruments and controls is not automated and you can't<br>
do that inspection without noticing the bear.<br>
