VTNA is year round 'flying club' type stuff. Powered Flight is run by VTNA in the summer training blocks.
they really seem to have ramped up the "aviation screener" aspect of the program. 150 page FTI, week of ground school with daily tests and followed by verbal checklist and EP tests and a blindfold cockpit test before ever getting airborne. failure on any single test results is a Training Review Board, and two failures can get you removed. all the flights are graded on each required Maneuver Item
Seems like overkill, but it gives them a good sense of what flight school feels like - firehose, pressure, etc
Probably a better idea of what you're getting into in regard to flight school. And for the people at USNA who are selecting who gets Aviation, I would guess it must be a decent predictor of performance in primary
EDIT - just realized this is an NROTC thread, so not relevant
