One proposed solution was the A team, B team and C team. A team is your fully qualified players - NIs, SWTIs, guys who are being groomed for the FRS, etc. They keep their quals and flight time and train the B team. The B team consists of the people who are preparing to deploy and need to be fully qualified for their mission sets. They fly enough to get qualified just in time to deploy. The C team is new PQMs, 2Ps who are returning from deployment and post-cruise HACs that aren't players. They fly whenever there are extra hours or an FCF needs to happen and there aren't enough A and B team people free.
This was HS in the early 90's. Only 2-3 JO's got Phase 3 qual (mission qual, equate to Level 3 now). With that qual came greater flight time since you were now part of the CSAR crew.
Much animosity developed among the JO's trying to position themselves to get the quals.
(There was no overwater quals at the time, so you were either a Phase 3 (low light missions qual) guy or you were not. Phase 2 (highlight missions qual) guys were limited in when they could fly, so if you weren't Phase 3, you weren't given as many flights.)
Some squadrons picked who got to CSAR Ground School (the doorway to Phase quals) by lineral number. Some squadrons picked their favorites (Please see MB's previous post as to how that worked out)
Please see the HS-15 mishap from 1996 to read more about the fracturing of a wardroom due to some getting quals and others not. Pilots, crewmembers and a SEAL are dead, the CO was relieved and the decision as to who got quals and who didn't was a significant causal factor in the AMB findings.
It was a bad idea then, it's a bad idea now.
