The requirement to get pilot is to have the required scores on the ASTB and pass the flight physical. I had tons of friends who never did aviation cruises but went pilot, but they were all USNA guys so training options are different. They will look at your grades, your evals, your LT's endorsement, etc. Remember they look at the whole package to make an evaluation. An aviation cruise wouldn't hurt as it increases your knowledge to the aviation world, how it works and could give you some good marks on a summer eval from cruise.
