My father was a WWII Navy primary flight instructor. I have his training syllabus from February 1943 complete with his notes. According to the preamble, Navy flight training was overhauled at that time to improve its effectiveness. It's a loose leaf binder along with a number of training pamphlets that were handed out to students when that particular subject area was to be covered. I haven't counted but it's probably about 100 double sided typed pages plus all of the pamphlets.
Bear in mind, this is the primary syllabus, not advanced or OTU.
Pilots returning from fleet deployment in 1940 / 41 could have wound up being primary instructors, but as far as I know, not after the war started. Combat experience wasn't wasted there, they would go to OTU or become cadre for newly forming squadrons. Primary instructors were trained as instructors under a special program (usually somewhat older civilian pilots who joined the Navy Reserves) or held back from graduating pilot classes.
