You need people not only typed but also VERY familiar with the way a specific company operates their airplanes and how their airplanes are configured.
Long ago, when I got my FE ticket, I was schooled on on Delta procedures and the inspector had worked with Eastern. Their electrical systems were configured differently and until I showed him the manual in answer to one of his questions, he had said I was wrong and I had failed the oral.
Recently, an FAA guy rode jumpseat with a check-airman I know at airline X. The crew used a proscribed procedure to navigate to the final course in an ILS. The FAA inspector said, "Glad you didn't use LNAV to do that or I would have busted you."
First, the 'bust' attitude shows the type guy on the jumpseat and second, using LNAV to intercept the final approach course is not only acceptable, it is the preferred method.
This is just more of the residual Oberstar circus a few weeks ago. Election year antics. Little more...
