Which option correctly identifies the MOS code 7599?

• A. Flight Instructor.
• B. Piloting Officer.
• C. Naval Aviator Candidate.
• D. Flight Student.

Answer: (D)

In naval aviation, codes like 7599 are used to show a person’s status in the aviation pipeline. The first two digits signal an aviation-related context, while the last two digits indicate status within that path. The ending 99 is used for someone who hasn’t yet been assigned a specific flight specialty, i.e., a Flight Student. That makes Flight Student the best fit for a code reading 7599, since it represents someone actively in flight training rather than someone who has already become an instructor, a designated aircrew member, or a candidate on a different path. The other roles describe positions you achieve after completing training, so they don’t align with the trainee designation that 7599 conveys.
