Currently, all USN WSOs begin their training as student naval flight officers (SNFO) at NAS Pensacola, Florida. Training begins with Introductory Flight Screening, where the WSO flies a Cessna 172 or Piper PA-28 variant to show he/she is competent enough in aviation to continue the rigorous training ahead. Then the SNFO starts the U.S. Navy indoctrination course called Aviation Preflight Indoctrination (API) with his/her student naval aviator (pilot) counterparts. After six weeks of ground school and basic water survival training during API, future SWSOs (Student WSOs), at that point known as student naval flight officers (SNFO) check into the primary Training Squadron for SNFOs, the VT-10 Wildcats.
