Gs award and pay doesnt wrk that way.

052 pilots have their good deals. Double pumps. Ot. And substantial schedule flexibility....as noted here.

And as far as i know.....duties in 052 are outside of any FAR 117 overlay for legalities to fly line trips at premium pay.

Is it fair a line pilot isnt available to award a gs due to block hour limits...while a 052 instructor is... even if that instructor has worked a full sim schedule plus OT sim periods?

You ask whats the big deal?

First you have non-operations pilots flying line pilot trips when their assigned dept and duties are elsewhere.

Second you allow management a defacto reserve pool of pilots instead of hiring and staffing enough line pilots as reserves.
