Ahhh man, I had a long response I was eloquently penning.
What threw me with your questioning was you referring to 'PIs'. It wasn't until this paragraph that you quoted the section regarding Evaluators.

Just so we're on the same sheet of music, there is no such thing as 'PI' or 'Standards Captain' anymore. Within the schoolhouse, as it pertains to Section 23, you're either an FIA 'I' (with different levels of quals and/or signoffs i.e. Validation, ETOPS, etc...) which determine your override or you're an 'E' (Evaluator). If you're an FIA - you're a First Officer when you fly and are paid as such by the department. Again, has no bearing on what someone holds on paper or where they show up in staffing. Evaluators are all Captains, and they are subject to the pay and section you quoted.

Both schoolhouses just interviewed and hired a massive number of 'I' only. I'm not aware of any 'E' positions, but there have been several LCA openings in various bases, particularly on the 756/76T.

If I only made things worse with my attempt to make sense of all that, drop me a PM. Cheers.
